These machines are programmed to make parts out of metal or plastic pieces. The computer-controlled machine tools cut, shape, drill, or otherwise change the metal or plastic. NC machine operators install the tools the machines need. NC machine operators may tend several machines. They may write, test, and correct programs.
Operators examine the finished products for problems.
They may use rulers or gauges when checking the workpieces. Increasingly the CNC machine tools will inspect the final product. Operators act as troubleshooters and monitor the CNC machines. Numerical Control Machine Operators is in the Manufacturing and Processing Career Cluster. Work Setting Numerical control machine operators work indoors.
