Description
CNC operators set up and operate machines that cut and form parts from all types of metal, plastic and other materials. Set up usually involves loading a computer program into the machine’s controls, but operators may also work from blueprints, layouts or other instructions. They use micrometers, gauges, and other precision measuring instruments, adjusting speed, feed and other variables as needed. CNC operators may compare the completed work with specified tolerance limits.
Working environment
CNC operators usually work in an enclosed manufacturing facility where numerous other machine tools are set up for manufacturing parts and assemblies. Most manufacturing facilities today are relatively clean, well lit and ventilated. Many computer-controlled machines are partially or totally enclosed, minimizing exposure to noise, debris and lubricants. However, working around machine tools presents certain dangers, and workers must follow safety precautions such as using safety glasses and earplugs. Because they must work where the machine tools are located, CNC operators cannot work from home. Full-time CNC operators work an average of 40 hours a week. Depending on the business, CNC operators may work a day, swing or graveyard shift. Most manufacturing facilities prefer to hire full-time workers, and they frequently offer overtime. Travel is usually not required in this position.
