CNC (Computer Numerical Control) Machine Operators are a pivital part of setting up, running, and reviewing CNC machine operations. After recieveing a blueprint from a CNC Programmer, a Machine Setter prepares the machine and runs a couple of test runs, the operator takes over. They may load the machine with metal or plastic and adjust the machine during production. During production, Machine Operators will periodically inspect the parts that are being created and adjust the machine's controls as needed. With the emergence of automation robots, Machine Operators may be running multiple machines at the same time. Requiring multitasking and attention to detail at the same time. Manufacturing companies typically have many CNC Machine Operators, working full time. To make production most efficient, the shifts may include nights, weekends, and frequent overtime.
