In fact, setting a dial bore gage using a micrometer may be the most common method used. However, doing so can be tricky when you are doing so alone and have only your two hands at your disposal. When in this position, a vise can come in very handy. You can use a vise as a means of holding the micrometer steady. It is advised that you wrap the micrometer in a towel if the vise you are using is not padded in order to protect your tool. Additionally, you can switch this method around and stabilize the dial bore gage in the vise while holding the micrometer in your hand. What these tricks do is allow you to have more freedom with your hands to do the actual setting. It will still be a bit tricky to accurately hold the gage extension to the micrometer spindle, but it will be much easier than trying to hold both tools steady at the same time.

Calipers are used to measure the distance between two opposing sides of an object in a variety of ways. These great devices come in a range of types, with three very common versions—Vernier caliper, digital caliper, and dial caliper. A Vernier caliper is the most common of all, and the most precise. A Vernier caliper includes a built in Vernier scale, which is a visual aid that indicates specific gradations between measurement marks. Utilizing a Vernier scale for measurement allows for an incredible degree of accuracy. A digital caliper is distinguished by the digital readout screen that displays the final measurement after the caliper has been adjusted appropriately.

Finally, a dial caliper is built with a small dial in place of the Vernier scale. The dial is rotated when taking a measurement and the final number will be in millimeters or inches, as read along the manual scale provided.

There are two main references to set when using a height gage: the internal zero and the ball diameter. A couple of key checks to run initially when setting these references are very important. First make sure that the surface plate used to set the internal zero is completely clean of any debris or dust; same goes for the ball. Second, make sure that both the surface plate and the ball are securely attached to the height gage and not at all loose. Both of these could interfere with the precision of your measurements. In order to set the internal zero of the surface plate, lower the sensing head and touch it to the plate. This will then be your baseline zero for any further measurements. Setting the reference of the diameter of the ball is equally important. The standardized text fixture and routine that accompanies your height gage should be utilized to set this reference point. As an extra precaution, the process of setting each of these reference points could be repeated a few times to ensure precision.
V-blocks are called v-blocks because their v-shaped design is central to how they function. A v-block is built with a v-shaped groove in the center of the tool where you place the cylindrical part with which you are working. This channel, or groove, is designed to be a 90-degree space located at a 45-degree rotation from both sides of the block. Positioned at evenly-spaced distances from each side as well as the base of the v-block, the groove is built to completely center and balance the cylindrical part you are drilling, milling, cutting, or inspecting. Cylindrical workpieces are difficult to work with in precision measurement tasks because of their shape. The precise design of the v-block is intended to solve this issue by making cylindrical parts stable during work.
Once you know the conformance standards and specifications that your caliper is supposed to align with, it is important for you to verify that conformance. One way to test the partial surface contact error conformance of your caliper gage uses gage blocks, a caliper checker, or another reference tool. Using at least three and at most five testing points, you will want to cover a minimum of 90% of the measurement range of the tool and to locate the reference standard tool along different positions of the caliper gage measurement faces. Testing the scale shift error conformance on a caliper gage similarly uses a caliper checker or gage blocks, but may also be done with a ring gage or surface face. What reference standard you use will vary depending on whether you are checking step, depth, or inside measurements. For guidance on choosing test points when calibrating and verifying your caliper gage, refer to the ASME B89.1.14. When doing this process with a used instead of a new caliper gage, just be sure to also check for wear and damage.
The technology behind the laser scan micrometer involves elements of simple optics. An object or part of interest is placed between the source of the laser beam and the receiving end on the micrometer. Then, a rotating optical element reflects or refracts the laser beam across the middle measurement area where the object or part is located. As the laser travels across this path, it is obstructed by the object or part, thus resulting in a shadow on the receiving end which is proportional in size and timing to the object or part being measured. The amount of the laser beam that successfully travels to the receiving end is collected and focused onto a photocell, where it is analyzed to detect the precise size and timing, which can then be converted into the final measurement.
The fundamental component of every Mitutoyo laser micrometer is the laser beam itself. The beam is directed toward a polygonal mirror that rotates within the device at a high speed while synchronizing with regular and stale pulses from a system clock. Once the beam is reflected, it rotates clockwise while sweeping across the input surface on a lens. The beam always changes direction in order to be horizontal following the lens exit surface. The horizontal laser beam enters the open workspace where a part may be placed. Should there be no interfering part being measured, the beam reaches a receiver through a condensing lens, thereby producing an output signal. The time during a sweep when the laser beam is interrupted by a part is indicated by the pulsing clock where the receiver signal is absent. This time is proportional to the part dimension in the downward direction. The edge is defined as each of the transitions between the receiver detecting the beam and then not detecting the beam. The edge marks the start or end of the measuring sections, allowing the differences in position of each edge to define the length of each section. These edges and sections are numbered sequentially and result in the eventual dimensional data output.
A telescopic bore gage measures the size of a bore through indirect methods. Essentially, the telescopic bore gage is used to take the size of a bore, and then an external tool, such as a caliper or a micrometer, is used to measure the output of the gage. The head of the bore gage is extended at an angle within the bore and locked into place. The extended head is the part that is measured to get the final output. Very similar to inside calipers, which can also be used to measure bore diameter, telescopic bore gages have the added advantage of being able to be locked in place during the measurement process, thus ensuring higher accuracy. Telescopic bore gages are used by mechanics and anyone in metrology that needs to find the interior diameter, radius, or circumferences of a pipe or a hole.
Given the global economy of today, parts and tools are made and shipped all over the world. That there are different methods of measurement in various countries will have a serious impact on trade, and requires an agreed upon method of measurement or conversion. Consider a manufacturer in Europe ships a part to a North American warehouse. They may have checked surface roughness originally in Europe and cleared the part using Rz, but a check at a North American location later will likely use Ra resulting in a different number. Quality control engineers must use this information and make decisions regarding whether to accept or reject parts. There are methods of converting Rz measurements to Ra measurements and vice versa. Luckily, the Mahr surface roughness testers are able to provide measurements using both Rz and Ra algorithms, thus simplifying the process of conversion and re-testing.

The Vyndicator Wireless Test Indicator consists of a transmitter and a receiver. The transmitter uses an attached stylus to send signals back to the receiver through a microprocessor connected to a sensor. Another microprocessor is located in the receiver, which decodes the signals sent from the transmitter. All of these relayed messages contain information regarding any movement of the stylus. The receiver then displays decoded information on its OLED display in regard to these movements, allowing the operator to complete necessary adjustments. A horizontal bar across the bottom of the receiver display represents the amount of distance the stylus moves, supplementing the numerical information provided.

Hardness, strength, and toughness are very similar concepts, but come with important distinctions. Hardness is simply the degree of resistance to deformation. Alternatively, strength refers to the amount of elasticity and plasticity of a material. In other words, how much can a material temporarily change shape (elasticity) and how much can a material permanently change shape without any damage (plasticity). These qualities in combination make strength. Toughness, then, is the greatest amount of energy that a material is able to absorb before breaking. This is distinct from hardness because hardness references the amount of force that can be applied before a change in structure. Toughness has to do with how much energy can be taken in by the material before a fracture occurs, and is sort of the opposing feature to hardness.
There are no set of rules or regulations that exist defining how often a gage needs to be calibrated. Ultimately, the frequency of gage calibration is up to the company or facility owner or manager. While some believe that annual calibration is a good rule to live by, there are resources at stake that must be considered. Calibrating one gage or multiple gages too often will waste a large amount of time and money. However, on the other hand, not calibrating a gage that needs it will result in poor accuracy. Calibration should definitely be done in regular intervals, but the definition of regular will vary based on the drift and use of a particular machine. Using historical trend analysis can help determine what gages require more frequent calibration and when to expect that they will need to be calibrated.
The MF-U series of Mitutoyo measuring microscope stands out from the other designs with its clear observation image and its incredible detection of microscopic flaws and asperities. Top-notch color quality, ultra-long working distance, and an apochromatic design that eliminates any chromatic aberration makes the MF-U an excellent choice. Additionally, these microscopes go above and beyond the standard availability of bright-field observation to also include the options of differential interference observation, simple polarized observation, and dark-field observation. The available polarization unit that comes with the MF-U series Mitutoyo measuring microscope increases image contrast when using a low-magnification lens.
Yes, granite is a far superior material for a surface plate than its comparators cast iron, glass, or metal. Granite comes with a number of advantages that overall allow your surface plate to last longer and to provide more reliable measurements. Granite does not rust or corrode overtime and it is almost impossible for granite to warp. Only under rare and extreme environmental circumstances would granite suffer the same damage that cast iron, glass, or metal might. When granite does get nicked or chipped, there is no compensatory hump. Granite has a longer wear life, a greater degree of precision, smoother overall action, a low maintenance cost, and a low coefficient of thermal expansion. Finally, there is no magnetic quality to granite with makes granite surface plates safer in the presence of multiple other materials.

No. Accuracy is different from resolution and in precision measurement it is important to know what they both are. The resolution of a gage is the degree to which the output of measurement can be broken down, whether in decimal places, parts, divisions, or counts. The smaller degree to which a gage is capable of making a measurement, the higher its resolution. Alternatively, accuracy is how close the output of a measurement is to the actual true value of the measurement. In other words, the less error there is in a particular measurement, the higher the accuracy of that measurement. A high functioning gage requires both resolution and accuracy—you need one to have the other.

No. Precision is different from resolution, just as accuracy is. The resolution of a gage is the degree to which the output of measurement can be broken down, whether in decimal places, parts, divisions, or counts. Precision relates to the resolution, but takes it a step further. The precision of a gage is the smallest (resolution), true (accuracy) measurement that can be taken repeatedly and reliably. The more precise a gage is, the greater its ability to take finely-tuned and accurate measurements again and again. While a gage might take the perfect measurement once, what you really want is to be confident that the gage will take as close to the perfect measurement as possible, every time—this is precision.

Yes, there are many kinds of micrometers out there. Some are basic micrometers, while others are specialized micrometers for particular jobs or measurements. What makes each micrometer unique is the kind of measurement purpose it serves. Universal micrometers are built with parts that can be swapped out depending on the job at hand. Blade micrometers, pitch-diameter micrometers, bore micrometers, tube micrometers, and bail micrometers are just few examples of micrometers with specialized parts that identify them for particular measurement goals. Digit micrometers use mechanical digit markers that roll and tell the measurement, whereas digital micrometers have an internal encoder that reports the measurement on a readable screen.

There are a number of different types of micrometers that you can buy to increase the versatility of your measurement workshop. While the more basic types of micrometer (inside, outside, and depth) will cover a number of measurements that you might be making, having a wider range of micrometers available will increase your measurement accuracy. Different micrometer types are built to specifically measure particular areas of a part, such as a screw thread, the dimensions of a groove, the various depths of holes, circles, tolerance limits, tubes and pipes, and much more. In measurement, precision and accuracy are key. The more specialized set micrometers you have, the higher levels of precision and accuracy you will achieve with your measurements.

It is completely normal for a micrometer to become un-calibrated. This is easily fixed by just recalibrating it. Often, you will be able to zero a micrometer by using a small pin spanner that adjusts the sleeve in order to realign its zero line with the zero line on the thimble. Once this adjustment has been made, you can double-check the accuracy of your micrometer by adjusting it such that the anvil and the spindle faces are touching, and seeing that the micrometer reads zero. Another way in which to test the accuracy of your micrometer is to measure a standardized item, like a gauge block or rod, for which you already know the exact measurement.

The resolution of your gage is pivotal to respectable measurement. In today’s world, technology is advancing at lightning speed. While there are bigger, more obvious ways in which this impacts the field of measurement, it also has a great impact on the smaller things too. The modern gage can be built to have an incredible degree of resolution. While a gage is used to conduct precision measurement on both small- and large-scale projects, this high resolution should never be sacrificed. The resolution of your gage is important in every practical setting because it directly impacts the accuracy of your measurement. Every project and measurement you take part in ought to value accuracy, and having high resolution is how this is done. No matter how basic the application, the technological advances that allow for incredibly precise measurement capabilities ought to be taken advantage of by all.

A go ring gage is made with the high limit of the part tolerance as well as a unilateral minus tolerance. Used in direct gaging, a go ring gage tests whether a part is oversized and therefore will not go through the ring. A no-go ring gage is built with the low limit of the part tolerance as well as a unilateral plus tolerance. The no-go gage tests whether a part is undersized by seeing if it passes through the ring and is also used in direct methods of gaging. A setting ring gage, or a master ring, is made to be used in methods of indirect gaging and serves as a comparator for other instruments which will then be used to test parts.
As a very common tool, you are likely to find a caliper gage under almost any precision measurement company brand name. Different brands may specialize in different caliper gage designs or sizes.

The main advantages of the Fowler QuadraTest Electronic Test Indicator over older dial style indicators relate to the way in which the measurement data is recorded, stored, and transmitted. From the initial step of taking the measurement, the electronic indicator will give a precise measurement without risk of a human misreading the dial. That data point can then be transmitted electronically, further removing any possible error made by a person reading the number and transcribing it incorrectly. All of the data points measured by the electronic indicator are easily sent and stored on a computer, formatted for any analysis that will occur. All of this results in much faster measurements, guaranteed to be more exact. Finally, the Fowler QuadraTest Electronic Test Indicator has the capability to switch back and forth between metric and inch units. This prevents error and enormously speeds of the process of changing or updating the data. Overall, the digital test indicators exhibit an increased amount of control over the measurement process.

Vernier calipers have been a staple in metrology tool sets for decades. These traditional tools provide extreme precision and accuracy in the measurements they take. Very adaptable, Vernier calipers can be used to measure inside and outside dimensions of a part as well as depth dimensions. Vernier calipers come with twin scales such that a main scale can be used with the secondary scale when measuring, thus eliminating the need for any external device like a ruler. Built using stainless steel, these tools are incredibly durable and made to last a lifetime by being resistant to damage and corrosion. Finally, since Vernier calipers are commonly used, they are also commonly made, which makes pricing competitive and low.
The Mitutoyo laser micrometers are incredibly versatile devices with numerous applications. Some of the potential measurement applications of these micrometers include in-line glass fiber or fine wire diameter, X- and Y-axis electric cables and fibers, film sheet thickness, disk head movement, thickness of film and sheet, outer diameter of opaque or transparent cylinders, outer diameter and roundness of cylinder, spacing of IC chip leads, gap between rollers, tape width, outer diameter of optical connector and ferrule, dual system for measuring a large outside diameter, as well as taper and form. The Mitutoyo laser micrometers come in a number of different models, each with varying measurement ranges, allowing for specification depending on your measurement needs.
Each of the series of Mitutoyo microscopes come with a range of optional accessories. The standard vision unit works to reduce the variation while improving efficiency in each measurement, and simplifies reporting and data storage. The vision unit dedicated software (QSPAK) allows for both simple and universal mode switching, editing of the measurement program, edge detection functions, simplified multi-point measurement, graphics, and quick navigation. Other adaptable software packages are also available. A few of the other available accessories for the Mitutoyo measuring microscopes include: calibration chart, C-mount adaptor, 0.5x TV adaptor, 2-dimensional data processing unit, foot switch, eyepieces, optical tubes, reticles, rotary table, stage adaptor, holder with clamp, v-block with clamp, swivel center support, vibration damping stand, mounting stand, illumination filter, ring light, dual swan-neck light pipe, and more.
Hardness can be measured in a number of ways, and often you will want to choose a particular measurement tool or scale based on the type of hardness you need to assess. We will review a few of the more commonly used tests. The Brinell Hardness Test applies a hard metal ball to the material being tested from a vertical angle, using a known amount of force, for a specified amount of time. The degree of hardness is determined from the pressure diameter and the force applied. The Vickers Hardness Test uses a pyramid-shaped diamond indenter to make an indentation on the test material. Hardness is then measured using the diagonals of the resulting indentation. The Rockwell Hardness Test uses a diamond cone or steel ball to make an indentation on the material being tested. A number is then calculated using the resulting depth.

Before the invention of the Vyndicator Wireless Test Indicator there were a number of cumbersome and dangerous jobs that can now be accomplished by this amazing measurement tool. These indicators can be used for standard quality control functions, to make sure that machines are well aligned. Beam deflections and shaft alignment can also be tackled by the Vyndicator Wireless Test Indicator. Machine debugging and repeatability, milling machine centering operations, and deep hole boring operations each come much easier with this useful tool available. Finally, the Vyndicator Wireless Test Indicator can even serve the purpose of replacing coaxial indicators.

Indicators are used in a number of different industries including machining, manufacturing, fabricating, and science. A Fowler QuadraTest Electronic Test Indicator might be used to assess run-out of an automotive disc brake, when working to fit a new disc. These indicators can be used to run quality checks regarding consistency and accuracy in manufacturing projects. Another application is initial or re-calibration of a machine before use in a production line, or testing accuracy of a tool in a tool production company. Also, many physics experiments and projects require the precise measurements offered by electronic test indicators.

Beyond the basic inside, outside, and depth micrometers, there are a number of specialized micrometers built for different jobs. Tube micrometers are utilized to measure the thickness of a pipe or tube, v-anvil micrometers can make evenly-spaced measurements around a circle, and universal micrometers are made to have interchangeable anvils in order to complete a wide range of potential measurements. Groove micrometers are put to use when you need to measure either the external or internal dimension of a groove, pitch-diameter micrometers are used to measure the height of the thread on a screw, and limit micrometers can ensure that a part is within the bounds of a particular tolerance. Finally, laser micrometers provide incredibly quick and precise measurements.
Taking care of your surface plate well is incredibly useful when it comes to getting your money’s worth and making it last. You want to make sure that you keep your granite surface plate clean. Airborne particles like dust, water, grease, and other abrasive substances that are present in the manufacturing workplace can wear out your surface plate over time. Relatedly, whenever you are not using your granite surface plate keep it covered to help protect it. Rotating the plate periodically can also help ensure that no one area is being used more than another, resulting in more equally dispersed wearing. Perhaps most importantly, do not use your granite surface plate for purposes other than its intended use. It is not a table or workbench and you can avoid unnecessary damage by not using it as one.
If you are using an electronic height gage, it will be capable of transmitting measurement information to a computer. However, some height gages go beyond this maneuver and are hooked up to the computer through a wireless connection. For a successful wireless set up with your height gage, you need a transmitter and a receiver, just like you do for wireless internet. The major advantage of wireless communication with height gages is that it eliminates the nuisance of having a wire connecting the tool to the computer and getting in the way of the operator. One potential risk of working with a wireless height gage is that there may be signal interference, or a problem with the transmission of the measurement information. However, the modern wireless height gage is advanced to handle this risk and is well-equipped to protect against any interference. Additionally, wireless transmission eliminates possible transcription errors, keyboard mistakes, missing data, and any number of other manual issues with data coding.
The newer ultralight calipers are superior to traditional Vernier calipers in a number of ways. Built using hollow aluminum with steel reinforcement, these tools are extremely lightweight, making them simpler to use and easier to transport. The model makes sure that the tools can be well-guided in measurement and ensures protection from shock. Additionally, the ultralight caliper has consistent pressure control during measurement, which makes the force involved both stable and parallel across both jaws of the tool. This feature is very advantageous because it improves repeatability when measuring larger diameters. The ultralight calipers are made with a titanium coating on surfaces exposed to other parts, helping protect from corrosion and scratching. These tools also come with a digital measurement readout. In general, ultralight calipers allow for the same or greater levels of precision and accuracy as Vernier calipers, with the added advantages of being simpler to use and having much more reliability.
The biggest benefit of using a caliper gage in precision measurement is the versatility of the tool. Caliper gages can measure any number of points of contact on a part or object, and has a much wider measurement range that similar tools. These great devices are able to be so flexible in measurement capability because of the hinged geometry technology used to build them. The jaws on a caliper gage have movement based on a gear within the pivot point, which can be re-enlarged by the same degree on the face of the tool. As long as a consistent 10:1 ration is maintained, you can adjust the jaws on a caliper gage to be almost any shape or size that you need. This allows the caliper gage to be used to measure distances, angled holes, flanges, curves, and hard-to-reach areas. While taking accurate and precise measurements using a caliper gage requires experience and practice, once you are well-versed in using these tools you can use them across so many different types of measurements. Having the skill to use a caliper gage is very useful to any metrologist.
The available models of the Mitutoyo laser micrometers and their corresponding measurement ranges are: LSM-500S (0.0002” - 0.08”), LSM-501S (0.002” - 0.4”), LSM-503S (0.012” – 1.18”), LSM-506S (0.04” – 2.36”), LSM-512S (0.04” – 4.72”), LSM-516S (0.04” – 6.30”). There is also a factory-set package for a complete measuring unit, the LSM-902/6900 which comes with a measurement range of 0.004” – 1.0”. The measuring unit with integrated display, or the LSM-9506 model has a measurement range of 0.02” – 2.36”. Finally, the display units themselves, in isolation, come in two different models. These include the LSM-6200 which is a multi-function version with a power supply of 100V – 240V AC and the LSM-5200 with is a compact version with a power supply of +24V DC.

The probes available as accessories to the TESA height gage by Brown & Sharpe include ball probes, disc probes, cone probes, shaft probes, cylindrical probes, and barrel probes. The most common type of probe used with height gages is the ball probe. These come prepackaged with each height gage. Typically used in order to complete bore measurements or to probe centering shoulders and grooves, disc probes are excellent to have around. Cone probes are made to position nicely at the center of a bore and can be used to find their location. Measuring grooves, blind bores, and centering shoulders can best be accomplished by shaft probes. Finally, probes that are cylindrical or barrel in shape are ideal when measuring elements that are more difficult to tackle using a standard ball-shaped probe.

The three models available for the Hi Cal Electronic Height Gage help you to customize your tool to the job you are completing. Each of these models comes with the same high quality and the same long list of amazing features.

Calipers are wonderfully simple tools used to measure the distance between two points on a part or object. Depending on the work piece, you might need to measure an interior distance, an exterior distance, a depth distance, or the distance from the side of the object to a particular point. All of these types of measurements can be accomplished using calipers. Overall, there are eight different caliper types today. The available varieties of caliper are the Vernier caliper, the dial caliper, the digital caliper, the inside caliper, the outside caliper, the divider caliper, the oddleg caliper, and the micrometer caliper. In fact, the micrometer caliper is the same tool as a micrometer, but using the full name.
The most important factor that impacts the accuracy of the measurement taken by a caliper is the skill of the operator. This is why it is important to choose the type of caliper that makes the most sense for the job at hand. If you choose a caliper that has more capabilities to complete an outside measurement, like a Vernier caliper, but do not know how to use it properly, you may negatively impact your accuracy. It is better to choose a caliper you know how to use in order to get a more precise and accurate measurement. Another factor to keep in mind is calibration. You want to make sure that if possible, your caliper is regularly calibrated. If you are working with an uncalibrated caliper (such as a one-purpose caliper like the inside caliper), then you will want to make sure that the measurement reference you are comparing it to is calibrated. Finally, to ensure accuracy of your caliper, you want to make sure that it always has a proper zero point. Mishandling of certain calipers can mess up the zero point as well as the eventual measurements.
Calipers are capable of measuring in four ways: 1) outside diameter, 2) inside diameter, 3) depth distance, and 4) step distance. Whether you have a Vernier, a digital, or a dial caliper, you will be able to complete all four of these potential measurements. Outside diameter measurement assesses the distance from one edge of an object to another using the outside dimensions. Inside diameter measurement looks at the distance between two inside points of a space or hole. Depth distance measurement provides the distance to the bottom of a space or hole. Finally, step distance measures the distance between an upper and lower step of an object. Calipers are incredibly useful because they can accomplish each of these different measurements. These highly adaptable tools are a great asset to any precision measurement workshop.
The grading system for granite surface plates is based on the degree of flatness and tolerance that is accomplished. The American Society of Mechanical Engineers (ASME) offers required specifications that go beyond the quality of flatness in order to standardize the use of granite surface plates. These additional qualities include: support point location, surface finish, methods of inspection, repeat measurement accuracy, material properties of granites, and more. However, the three main grades for standard granite surface plates follow the federal specifications for flatness tolerance. Those grades are: Laboratory Grade AA which means the plate has a flatness tolerance equal to (40 + diagonal squared/25) x .000001" (unilateral), Inspection Grade A which has a flatness tolerance equal to Laboratory Grade AA times two, and Tool Room Grade B which has a flatness tolerance equal to Laboratory Grade AA times four.
While there a couple of methods of setting a dial bore gage, no method is perfect, and choosing one will likely depend on preference and availability of tools. First, you can set your dial bore gage using a micrometer. By placing your gage between the spindle and anvil on the micrometer, and zeroing the indicator to the minimum reading provides your nominal size. Second, you can use a set of master rings in order to set a dial bore gage. This method is very precise, but can be costly depending on the number of master ring sizes you require. Third, you can use gage blocks to represent your desired nominal size and set your dial bore gage in this way. Gage blocks are often easily accessible, but this process takes a bit more time. Metrologists will likely have their own method of choice for setting a dial bore gage, but knowing how to use these multiple methods can come in handy depending on tool availability and the circumstances of the measurement.
There are three most basic categorizations of micrometers. Those types are inside, outside, and depth micrometers. The reason that these are known as the most basic types is that the majority of the measurements you may need to complete can be accomplished with these tools. An inside micrometer is used to measure the internal dimensions of an object, an outside micrometer is used to measure the external dimension of an object, and a depth micrometer is used to measure the depth of a hole. In fact, the outside micrometer is one of the most widely used precision measurement tools overall. These versatile micrometers are excellent devices to have on hand no matter what specific type of metrology you do.
The first level of electronic height gage functions very similarly to a mechanical height gage. They will have a comparable level of accuracy to a mechanical height gage. Additionally, these will include both a floating and an absolute zero, data output, and data unit conversion. The second level of electronic height gage builds upon the first group. This level will have an increased degree of accuracy, and might possibly come with more advanced features. Some of these features could include a tolerance setting, a maximum and minimum setting, TIR compensation, ID/OD measurement, or a probe compensation. Finally, the third level of electronic height gage contains all of the features of the first and second level, with higher accuracy and more features. The additional features you will likely see in this group are a motorized touch probe, a computer interface, air bearings, and the ability to store part programs.
Hardness in general is the amount of resistance a material has to any kind of deformation from an outside source. The three main types of hardness include: indentation hardness, scratch hardness, and rebound hardness. Indentation hardness is the resistance a material has to deformation from a consistently applied force. The higher the indentation hardness, the greater ability to not have any resulting deformation from applied compression. Scratch hardness is the degree of resistance one material has when it is subjected to friction caused by another material. Materials that are less impacted by this scratching will have higher scratch hardness. Finally, rebound hardness is the amount of bounce that occurs when an outside object is dropped on the material in question. Often tested with a diamond-tipped hammer, a material with higher rebound hardness will lead to a higher bounce when the hammer is dropped.
The two main types of measurement conducted by the Mitutoyo laser micrometer are diameter measurement and interval measurement. In diameter measurement, the object or part which you need to measure is placed centrally into the laser beam of the micrometer. Then on the central display device, the measurement of the diameter of the part can be read. Alternatively, with interval measurement, two parts or objects can be placed within the laser beam of the micrometer. The readout then provides the distance between the two parts. Furthermore, when using interval measurement, the furthest distance between the two parts can also be measured.
The overarching name given to the wide ranging software packages available through Wyler is wylerSOFT. Built within this greater program are a series of important subsets that can be combined or not to create an incredible suite of precision measurement software. WylerSPEC is a tool used for measurement tasks concerning the geometry of objects and machines, calculating measurements of flatness, parallelism, and squareness. WylerDYNAM samples and analyzes data in order to measure and display inclinations, profiles, and more for both stationary and moving objects. WylerCHART is based on wylerDYNAM but is preconfigured to launch standard applications right away, making it very simple to use. LabEXCEL CLINO displays the measurement values determined by the Clinotronic inclination measurement instruments. WylerINSERT reads values taken by the Wyler BlueSystem devices and inserts them into any other program that you are using. Finally, Wyler sells a software development kit that customers can use in order to develop their own software for analyzing data from Wyler instruments in order to better customize the tools to their needs.
Above and beyond the basic concept of the laser scan micrometer, these tools come in different varieties and with different accessories that help to specify their measurement capabilities. They can be purchased in different sizes and models. Additionally, you might need a laser scan micrometer with a separate display unit or an integrated display, both of which are available. The four main types of laser scan micrometer include the automatic (sometimes called the inline), the bench-top (sometimes called the floor), the handheld (sometimes called the portable), and the machine-mounted. The typical optional accessories that are available alongside laser scan micrometers include: a workstage or an adjustable workstage, a calibration gage set, a wire guiding pulley, extension relay cables, extension signal cables, air-screen covers, and air-blow covers.

In build and capability, a Vernier caliper, a dial caliper, and a digital caliper are all very similar. However, they also have important distinguishing features. All three of these caliper types are built with multiple functional measurement techniques. With inside jaws, outside jaws, and a depth probe, these calipers can complete almost all of the same measurements as the one-purpose calipers. One disadvantage of being multi-faceted is that these calipers may not be quite as flexible in range of distances as the one-purpose calipers, like an outside caliper. The central distinguishing feature of these calipers is the way in which the measurement readout functions. On a Vernier caliper, there is a Vernier scale with gradation marks that minimize operator error and improve interpolation. On a dial caliper, the readout is a simple dial face. These are good for completing differential measurements. Finally, on a digital caliper, the readout is a digital face. These allow for very precise measurements and may even be easily connected to a computer for data recording and collection.
Setting a dial bore gage refers to the process of aligning the gage to a required zero point. The zero point is the nominal size, or reference point, that you use when taking the measurement of a bore. There are a number of ways to set a dial bore gage, but the end goal is always to match the zero readout of the gage to the nominal size you are striving for. The outcome of a properly set dial bore gage is being able to easily read off the measurement of a bore as it compares to the zero point on your gage. Any variation away from the zero point is your final measurement. Setting your dial bore gage before each use is important to ensure accuracy in every measurement.

The TESA Micro-Hite height gage by Brown & Sharpe is used in all kinds of metrology and a number of different industries. Mainly, these include automobile, moulds and tooling, medical, or plasturgy industries. In the automobile industry, height gages might be used to measure injection systems, brake systems, or engine components to ensure quality and precise design. The complexity and exactitude involved in moulds and tooling requires an excellent machine such as the Brown & Sharpe height gage. These height gages are vital to measuring various molds and tools that are then used to create millions of copies of different foods, aeronautics, cosmetics, etc. The standards set within the medical field are very high, and the controlled nature of medical devices and tools is very strict, since their eventual use involves high risks and high rewards. Brown & Sharpe height gages are built for excellence, and come equipped with the high-level analytic capabilities, regulatory compliance, and measurement precision that are imperative to the medical industry. The variability of plastic development and the regularity of product within the plasturgy industry is the perfect place to see the Brown & Sharpe height gage shine. This tool has the validity and stability that is essential to all processes in working with plastics.

The zero error on a caliper has to do with the baseline point of the caliper. If properly cleaned and closed, a caliper ought to measure 0.00 exactly. Occasionally, this will not be the case and then you have a zero error. A zero error on a caliper can be positive or negative in direction. A positive zero error occurs when the caliper jaws are closed, but the readout has some positive value, whereas a negative zero error occurs when the caliper jaws are closed, but the readout has some negative value. This can occur when a caliper is not properly maintained, or after normal wear and tear from use. No matter the cause, a zero error occurs when the caliper is not properly calibrated to the zero point. Knowing if your caliper has a zero error is extremely important for the accuracy of your measurement. If there is any discrepancy in the calibration of your caliper, you must then account for it in your final measurement.
Average Roughness (Ra) is an algorithm used to measure the roughness of a particular surface. Ra is the most commonly used parameter of surface texture in North America, as opposed to Mean Roughness Depth (Rz), which is used most commonly in Europe. The average length between the valleys and peaks across a surface is found, and then the deviation from the mean surface line across the whole measured surface within the sampling length is determined. When using Ra, all extreme outlier points of measurement are neutralized in the calculations such that they do not have a significant impact on the final output. Ra is known for being a simple and consistent parameter of surface roughness. Each of the Mahr surface testers offers a readout for Average Roughness (Ra).
The process of direct gaging is when a ring gage is utilized as a means of checking the size and/or roundness of a part. When conducting direct gaging, the ring gage can either be a go ring gage or a no-go ring gage, sometimes known as a not-go ring gage. Direct gaging, or fixed-limit gaging works to establish a physical limit for the acceptable outer diameter of a part. Depending on the high limit (go gage) or low limit (no-go gage), it can be determined whether the part is oversized, undersized, or within an acceptable limit. Additionally, direct gaging is useful for testing the roundness of a part that might be missed when using a micrometer or some other tool as a comparator.
The process of indirect gaging involves using a ring gage as a reference point against which to set other measuring tools or instruments. Because the ring gage itself is not being used to test the final part, but rather to set another tool which will test the final part, this process is indirect. In essence, two tools are used in conjunction in order to assess the acceptableness of the part being measured. When conducting indirect gaging, the ring gage is known as the master ring or the setting ring. The unique feature of a setting ring is that it is built with a bilateral tolerance. A bilateral tolerance is defined as one half of the specified tolerance added and subtracted from the designated size. This measurement ought not to deviate any more than 0.00001in from the ring gage nominal size.
Mean Roughness Depth (Rz) is an algorithm that is used in order to measure the surface roughness of a part. Rz is the most commonly used parameter of surface texture in Europe, as opposed to Average Roughness (Ra), which is used most commonly in North America. The vertical distance between the lowest valley and the highest peak from five different sample lengths from the surface are found. These distances are then averaged. When using Rz, any extreme outliers have an enormous impact on the final measurement due to this method of averaging. Rz can be measured through three different calculations that have changed over the years, making it important to know which algorithm is being used. Each of the Mahr surface testers offers a readout for Mean Roughness Depth (Rz).

Measurement conflict resolution, sometimes called measurement dispute resolution, is when a suppler and a user disagree on the finite measurement of a gage or precision measurement instrument. Such conflicts can gravely impact relationships within the field. Most experts suggest that having methods in place ahead of time to resolve any measurement conflicts can lead to a quicker and more satisfactory resolution. Vermont Gage subscribes to the methods used by the American Measuring Tool Manufacturers Association (AMTMA). These methods include “The Referee Method” and “The Universal Standard Method.” The Referee Method involves an uninvolved third party taking a measurement of the disputed part or tool that will then serve as the agreed upon true measurement by both disputing parties. The Universal Standard Method involves focusing on uncertainty budgets of the involved parties. In this method it is up to the party questioning the validity of the measurement to present their uncertainty budget to the opposing party with the goal being to resolve that incorrect parts of one budget with the correct parts of the other.

While different experts in the field of metrology have differing opinions on how often gages need to be calibrated, one thing is agreed upon—there must be some sort of calibration schedule. One potential solution to regular gage calibration is to create a gage control program. Very simply, a gage control program is a systematized way to determine how often a gage requires recalibration. The central goal of a gage control program is to create a document that names each gage, records the intervals of calibration, and classifies the gage within a bigger system of groups defining when calibration will occur. This document then allows you to see when a particular gage was last calibrated, how often it has been calibrated over time, how frequently it is utilized, and who is charge of maintaining its use.

Small hole bore gages come in two main types: full-ball and half-ball bore gages. The terms full- and half-ball refer to the end of the bore gage that is inserted into the bore to complete the measurement. This end is typically opposite to the knurled knob used for setting the anvils. Full-ball small hole gages are generally simpler to set the anvils on and lock into place. More often than not, these bore gages will provide a more accurate and precise measurement of a bore. Half-ball gages are more prone to springing during measurement and require a more experienced user. Half-ball bore gages are more likely to result in an inaccurate measurement. However, some machinists prefer half-ball bore gages because they allow the user more control and leave room for adjustment in unusual measurement circumstances.

The total indicator reading (TIR), sometimes called total indicator run-out (TIR) mentioned for the Fowler QuadraTest Electronic Test Indicator refers to the difference between minimum and maximum measurement. In other words, the TIR measures the amount of deviation from whatever the targeted structure is (flatness, concentricity, cylindricity, roundness). The TIR is the value measured about a particular reference axis. TIR is highly important in preventing excessing stress, premature wear, and a failing system. This is because TIR assesses whether the central axis that is being measured is unequal in direction and/or angle.

Human error is unavoidable in any profession. Similarly, in precision measurement, the height gage operator is a crucial factor in its accuracy and success. This is particularly salient when an operator is working with a manual height gage. The speed and pressure with which a part is touched onto a height gage can significantly alter the outcome of the measurement and introduce variability. Due to this potential for error, operators must go through very regimented and precise training in order to properly learn how to operate a manual height gage. The icons on a height gage have been specifically developed to be intuitive and instructive for use in order to aid the operation of the height gage. Finally, the more electronic the height gage, the less pressure that falls onto the operator, resulting in the minimization of error in accuracy due to operator involvement.

Micrometers are certainly built to last, but that does not mean that you should skip these quick and simple steps to make them last even longer. First and foremost, take care to not drop your micrometer, or slam it down on any surface. This could impact its measurement accuracy. If you do accidentally drop it, make sure to recheck the calibration before using it for measurements. Another important habit to develop is to wipe down your micrometer on a regular basis. Particularly, you want to wipe the measurement faces in order to ensure that no dirt or build up impacts your measurement. Use a dry, lint-free cloth to do this. Also using a lint-free cloth, wipe your micrometer with a very small amount of oil after long periods of non-use or storage. This will help to avoid the build up of rust or other corrosive mater. When storing your micrometer, keep it in a place that is as close to room temperature as possible, with as low humidity as possible. This will help prevent warping of any sort. Finally, when your micrometer is not in use leave a gap between the anvil face and the spindle face. Prolonged contact between the two faces could lead to a less accurate measurement.

The broad categories of types of caliper gages include, digital caliper gage, dial caliper gage, external caliper gage, internal caliper gage, metric caliper gage, and inch caliper gage. Digital and dial calipers differ in build and output style. Some metrologists prefer to have more manual control over a measurement, and therefore may prefer a dial caliper gage that allows them to determine the output. Others might like the consistency offered by an electronic tool design and the digital output option. Internal and external caliper gages differ in what they are intended to measure. Internal caliper gages take inside measurements of an object, while external caliper gages take outside measurements. These calipers require gentle handling so as to avoid bending or damage during adjustment and positioning. Metric and inch caliper gages simply differ in the unit of measurement output. Most often, caliper gages are built as overlapping types rather than each one of these types being built independently. Caliper gages are commonly able to switch between metric and inch output and likely can manage both manual and digital measurements. Something to keep in mind when buying a caliper gage is that if you do not see a specific design feature that you have in mind, just ask. These tools come in a huge variety and there may be a way in which to create the specific caliper gage you are hoping for or to adjust another version to match the needs you have in mind.
A major benefit of laser scan micrometers is how versatile they are in terms of types of measurements they are able to complete. Due to this versatility, there are a range of measurements that fall under the domain of laser scan micrometers. These include, but are not limited to, in-line glass fiber or fine wire diameter, outer diameter and roundness of cylinders, thickness of film and sheet, gaps between rollers, film sheet thickness, taper and form, outer diameter of optical connector and ferrule, outer diameter of opaque or transparent cylinders, X- and Y-axis electric cables and fibers, spacing of IC chip leads, disk head movement, and tape width. Additionally, laser scan micrometers can be used in pairs, thus serving as a dual system for measuring a larger outside diameter of a part or object.

V-bocks are typically made out of either cast iron or steel and you will want to consider the types of materials you will be working with when choosing what material is best for your v-block design. When looking at v-blocks for purchase, you will notice two different grades, Grade A and Grade B. These are the two grades specified by IS: 2494-1964. Generally, v-blocks will have a bearing area of greater than or equal to 20%. The tolerance of a v-block is the maximum amount of distance separating two imaginary parallel places between the enclosed part. V-blocks are known to have symmetrization accuracy of 0.002 mm per 20 mm length in the vee groove and straightness accuracy is ±0.01 mm per 20 mm length. When shopping for a v-block, you will notice four faces: the flanks of the vees, the base end faces, the top, and the sides faces. V-blocks are usually sold in pairs matched in grade and size, allowing you to work with larger or longer cylindrical parts. Some v-blocks have two vees such that one is wider and deeper than the other. Another option when considering v-blocks are ones built with a 120-degree angle in order to check triangle effects or taps.
The TM series measuring microscope was released by Mitutoyo with an ergonomic design and newly enhanced features. The LED illuminator built into each microscope was newly designed for improved observation in the TM series. The base design of this microscope was modified with a lateral notch, built to make the tool easier to move around and carry. The optical camera adapter on this model also improved the microscopes design, as did the new AC adapter which was included to cover a wider range of voltages. Overall, the TM series measuring microscope was designed to be adaptable in high traffic work settings while having a smaller footprint on the environment. The TM series of Mitutoyo microscope is ideal for measuring machined metals, particularly when measuring dimensions and angles, or when checking gears or screws after attaching a reticle.

A man named William Gascoigne invented the very first micrometer in the 1600s. This micrometer was used to measure the distance between stars through a telescope, and to estimate the size of various celestial objects. Later, in the 1800s, Henry Maudslay upgraded the micrometer to a version built for mechanical use. This tool was made to be durable as well as accurate. Then, later in the 19th century, Jean Palmer created a handheld version of the micrometer, making it much more accessible and popular in industrial fields. The micrometer at the time represented an excellent pairing of technology and science. Today, the micrometer remains one of the most important tools in the industrial world, having many applications and reporting consistent and trusted measurements.

Due to their lightweight structure, ultralight calipers are easier to learn how to use than Vernier calipers. While they are known for having high levels of accuracy and precision, Vernier calipers are also notorious for not having great repeatability and for being difficult to learn how to use. Better measurements from a Vernier caliper require a high level of expertise for the operator. Alternatively, ultralight calipers are much easier to learn because they require less expert use and allow for clearer measurements. They are simpler to align properly and offer a digital measurement readout helping to assure reliability and accuracy.
Gage calibration can be done by the owner or facility manager him or herself, it can be outsourced to a commercial calibration service, or it can be done by the original manufacturer who built the gage. There are pros and cons to each. Doing the calibration in-house can be a huge investment to set up the facilities, but can also save time and money. Outsourcing can guarantee that specialists complete the calibration, but can lead to long turnaround time. Going back to the manufacturer ensures that the gage is in the same setting it was originally built and tested in, but can also add to the time or cost of moving the machine. Usually, gage owners will use a mix of these three options dependent upon the work that needs to be done and the speed with which it needs to be done.

The type of bore gage required will vary depending on the measurement job at hand, as well as on the preference of the user. Dial bore gages are often an excellent choice when needing to conduct a highly precise measurement of a bore. The biggest benefit of the dial bore gage is that it does not require the transferring of the measurement to another tool (micrometer or caliper), but rather has a built in mechanism so that a bore can be measured directly. In general, dial bore gages are both highly accurate and highly fast. Additionally, a dial bore gage comes in handy if the user needs to assess a bore for wearing or tapering that could impact the roundness and symmetry of the bore. Dial bore gages come with a very high resolution, usually reaching an accuracy of 1/100 of a millimeter or 5/10,000 of an inch.

The color of a granite surface plate reflects the material of which it is made. The most standard type of granite surface plate is made of black granite and will appear the color black. When other minerals are added to the granite, the surface plate will appear a different color and have different properties. For example, another common type of granite is pink granite which includes quartz. Depending on what you are utilizing your granite surface plate for, you will want to determine the specific make up you require. Each type of granite comes with slightly different properties.
