CNC Cutting Machine Practice Test

The correct response is that programming software is not counted among the six major components of a CNC machine. Generally, the six main components of a CNC machine are the part program, machine control unit, drive system, feedback system, power supply, and the machine itself (which includes the mechanical components). Programming software, while essential for creating the part program and facilitating operations, serves more as a tool for users rather than a fundamental hardware or structural component of the CNC machine. The part program specifies the exact movements and operations the machine will perform, while the machine control unit processes this information to direct the machine's movements. The drive system provides the necessary power and actuation, completing the loop of operation.
