Inspecting a Cylindrical Part

A number of instruments have the right amount of sensitivity required to inspect most cylindrical parts, but a CMM is often the most accurate. Inspection starts by measuring each size dimension in two ways: the cross-sectional dimension, or actual local size, at one location along the part and the actual mating envelope (AME) along the part’s entire length. Cylindrical parts are also routinely inspected for certain geometric tolerances. The ways in which a part must be inspected is based largely upon its shape. Thus proper inspection of a cylindrical part requires an understanding of its basic dimensions and tolerances. After the class users should be able to describe best practices for inspecting the complete layout of a cylindrical part.
