What does a CNC machine operator do?

The job duties of a CNC machine operator involve working on the setup and operation of a computer numerical control machine. In this career, your responsibilities may also include the maintenance of equipment. CNC machine operators control operations by using geometric code (G-code) to program an automated task. Depending on the type of production process, you may need to plan logistics before programming the machine. Manufacturers use CNC machines for a variety of products and purposes, including metalwork and auto parts manufacturing. A machine operator may inspect the output during production to assess quality.
