Our ISO 9001 compliant quality management system (QMS) features up-to-date calibrated inspection equipment. Our exceptionally skilled metrology personnel combined with precise inspection tools ensure that our customers are receiving products that are within the specified tolerances and comply with geometric dimensioning and tolerancing (GD&T) requirements. Using ANOVA repeatability and reproducibility (R&R) with our QMS, we check the precision of the gages that we manufacture.
Coordinate Measuring Machines
A coordinate measuring machine (CMM) is a common tool that's used to accurately measure the geometrical dimensions of an object. CMMs are used to inspect a part to ensure that it's within the specified tolerances. A probe is attached to a movable arm (axis) which takes the x, y, and z coordinates down to a micrometer or less. They are also used to reverse engineer objects, as well as provide the necessary coordinates to create a solid 3D model in a CAD program.
Scales such as Rockwell, Vickers, Shore, and Knoop are used to measure the indentation hardness of metal. This test is commonly used to determine the hardness of an object to ensure that it complies with the specified hardness rating or after it has been heat treated. A load is applied to the surface of the metal with an indenter, and the depth of indentation is measured to produce a hardness number. The benefits of this nondestructive hardness testing is speed, reliability, and small area of indentation which won't affect the function of the object.
An optical comparator operates by displaying a silhouette of an object on a large screen with the ability to measure the dimensions (including angles) and geometries. Graduations are shown on the screen to line up the feature of the object and a digital readout is used to show the dimension. Despite this metrology tool being dated, it is still used to quickly and accurately measure complex geometries that are unable to be measured using conventional methods.
