Inspection and Measuring Equipment includes all of the tools and devices that are used to verify that a part’s dimensions all conform to the tolerances required by the part’s design. Included are various hand-held gages such as calipers and micrometers, as well as more simple gage blocks or plug gages. However, inspection and measurement in most shops also goes beyond hand-held gages to include coordinate measuring machines (CMMs), the measurement machine tools able to execute programmed measurement routines. Also included in this category are devices such as profilometers that measure the finish of machined surfaces.
