Referring to human relations, my father advised me always to "save the surface," which is something like "don’t burn your bridges," only more subtle. The connection between the homilies becomes literal in the paint industry: You must save the surface of an iron bridge to avoid burning…

The pipette is a reliable precision instrument that has been used and trusted for many years. However, as with many forms of instrumentation, a pipette performs only as well as the operator’s technique allows. Differences in technique—some more than others—can alter delivery volumes and affect data…

No, this isn’t about promises you made on New Year’s Eve and broke the next day. It’s about measurement resolution—the number of decimal places to which a measured value is calculated and presented. The measurement can be of any parameter—voltage, distance, weight, temperature, whatever. The…

Many people know about William Tell shooting the apple on his son’s head. What can this archery event teach us about accuracy and precision? What do these words mean? When are they equal, and when are they not? “Accuracy,” “precision” and “resolution” are sometimes misunderstood or…

Measurements add value to the parts you manufacture. That may not be a widely accepted position, because the act of measuring is an additional step in the manufacturing sequence, and every step has a cost associated with it. With pressure to reduce costs and improve productivity, some might think…

Metrology is the science of measurement. It’s a very broad topic because so much is measured. In manufacturing, the need to verify and validate dimensions of parts is crucial. These dimensional measurements are done at many stages in the manufacturing process with a range of devices, from simple…

Machine tool and manufacturing system builders have been producing increasingly intelligent equipment for more than 50 years, and today’s computer numeric controlled (CNC) machines and systems are marvels of technology. However, they still need intensive human supervision and…
The need to measure things inspired some of the earliest tools invented by man. Basic measurements were needed for constructing dwellings of an appropriate size and shape, fashioning clothing, or bartering food or raw materials. Understandably, early man turned first to parts of his…

When purchasing material test equipment for tensile, fatigue or other test modes, managers of test labs may want to compare new and used test equipment due to budget constraints or other factors. The problem is that there’s currently no easy way to determine if a particular used test…
Laser scanning makes it easy to keep older military equipment running by enabling companies to create spare parts that perfectly duplicate the originals at a reasonable cost. Manufacturers of weapons systems are taking advantage of new technologies, particularly the ModelMaker laser scanning…

Switching from a coordinate measuring machine (CMM) to a laser scanner has helped the National Aeronautics and Space Administration, Langley Research Center, increase the accuracy of models used to evaluate proposed spacecraft designs in wind tunnels. Accuracy is critical for the 6- to 12-in. scale…

Laser scanning keeps older military equipment running by enabling the creation of spare parts that perfectly duplicate the originals at a reasonable cost. MILPARTS and other companies are taking advantage of new technologies, particularly the ModelMaker laser scanning system, which make it possible…

What is calibration anyway? Many people do a field comparison check of two meters, and call them “calibrated” if they give the same reading. This isn’t calibration. It’s simply a field check. It can show you if there’s a problem, but it can’t show you which meter is right. If both meters are out…

Foam Design Inc. of Lexington, Kentucky, builds a wide range of foam parts, including inserts for headliners used to protect against injuries in the event of a collision. Inspecting these components with a CMM was a tedious and error-prone process because of the difficulty involved in making…

By adding a laser probe to a coordinate measuring machine (CMM), Sonaca, a large Belgian aerospace-structures supplier, has greatly increased the completeness of its inspections, obtaining full documentation of every component’s geometry. When the company inspected sheet metal components in the…
Pressure decay has been the most widely used method of leak testing in manufacturing production lines for decades. The process is uncomplicated, inexpensive and easily automated. Air is simply injected into a test object and any decrease in air pressure over time signifies a leak. However, the…

So you have a great product, and there’s a great demand for it. You’ve addressed how to quickly produce it, and now you need to ensure the quality—fast. You can’t afford delays and need to keep costs down. One way to accomplish this is with fixture gaging, a simple, easy-to-use quality control…

As industry standards increase, so too does the demand for flexibility in specialized gaging procedures. Because there’s no room for error, choosing the right contact point or styli is paramount in conforming to the organization’s high quality standards. Accuracy can be jeopardized by any number of…
Many customers come to Hobson & Motzer seeking a solution for what others have claimed is impossible. Established in 1912 and based in Durham, Connecticut, Hobson & Motzer engineers manufacturing processes and designs tooling to produce seemingly impossible parts for companies worldwide.…
Test and measurement equipment (T&ME) must be periodically calibrated to ensure it’s operating within its specified parameters. Of course, the uncertainty of the system used to calibrate the equipment shouldn’t add appreciable error to this process.Test and measurement equipment (T&ME) must…

Shortwave infrared (SWIR) imaging is quietly earning a growing place in industrial machine vision for quality inspection. SWIR imagers, sometimes also referred to as NIR imagers, can see objects and events that vision and thermal cameras cannot. Moreover, they’re’ smaller and lighter than all…

How many dimensional data points are enough to accurately describe a part feature? The key to answering this question is understanding the stability of the manufacturing process. In general, components should be measured only as often as required to ensure the stability of manufacturing processes.…

Coordinate measuring machines gather data by means of a probe or sensor. Conventional CMMs equipped with touch-trigger probes can use a stitch-scanning method to record point streams from part surfaces. In stitch scanning, the CMM lifts the probe head from the surface of the part, moves it slightly…
