A CNC Machine Operator is someone that runs production parts in a machine shop. They load and sort parts on a CNC machine, whether it be a milling center, turning center, or other computer-controlled machine.
There are many jobs available for cnc operators because schooling is not necessarily required. A machine operator can get trained in by the CNC Machinist or shop foreman on how to do the required tasks. Any school that has a Machine manufacturing program will teach you how to run machines, make and inspect parts, and how to do well in the industry.
