Final answer:
The machine control unit executes part programs on an NC machine by interacting with components like PLCs and built-in machine memory.
Explanation:
Machine control unit is the device that executes part programs on an NC machine. It is responsible for processing and decision making in conjunction with components like microcontrollers and PLCs.
The program logic controller (PLC) is another essential component involved in executing part programs on NC machines. PLCs are commonly used in industrial automation for controlling machinery and processes.
Additionally, in the context of NC machines, the built-in machine memory plays a crucial role in storing the program instructions that are to be executed by the machine control unit.
