A CMM Operator is in charge of operating a coordinate measuring machine. They use a coordinate measuring machine to measure parts, prototypes, and check dimensions against a blueprint. They typically measure products that companies manufacture and document their specifications. The duties of a CMM operator are to inspect fixtures, check for certification, and communicate any issues. Other responsibilities include keeping a record of inventory and maintaining the machine’s software capabilities. Qualifications to become a CMM operator often include an associate’s degree or certificate as well as some experience in manufacturing. A bachelor’s degree may be required to advance in the field.
