Computer Numerically Controlled Tool Operators
CNC tool operators run computer-controlled machines that cut, shape, and finish parts from metal, plastic, wood, stone, and other materials. They work in manufacturing facilities, job shops, and production plants, where they follow programmed instructions to produce precise components. Some operators also set up machines and perform routine maintenance.

A day in the work
A typical week involves loading raw materials into machines, entering or loading CNC programs, and monitoring the machining process to ensure accuracy. Operators measure finished parts with gauges and calipers to verify they meet specifications. They troubleshoot problems when parts don't meet tolerances, make adjustments to machine settings, and perform cleaning and basic maintenance. The work requires attention to detail and the ability to read technical drawings and blueprints.
