Inspecting with CMMs 361

Inspecting with CMMs provides a comprehensive overview of the functions and mechanics of the coordinate measuring machine, or CMM. A CMM’s probe contacts the various features on a workpiece and records their Cartesian coordinate locations with software. CMMs measure using either contact or noncontact methods and can be used in a lab or on the production floor. CMMs use either manual operation, joystick, or DCC to guide components. As long as the operator is trained in its use, the CMM provides high accuracy measurements with minimum human influence in a very short amount of time. This allows the operator to respond to machining errors and reduce scrap. After this class, users should be able to describe best practices for using the CMM to inspect parts.
