What is the role of the CNC control system?

The CNC control system is essential for the operation of CNC machines because it interprets the program code that dictates how the machine should behave. This includes translating instructions from computer-generated code (usually G-code) into precise movements and actions of the machine components. The control system manages the axes movement, spindle speeds, and tool changes, ensuring that the machining process is executed accurately according to the specified design.

The other options describe important functions but do not capture the primary purpose of the CNC control system. While managing the supply of raw material is crucial for production efficiency, this task does not fall under the control system's responsibilities. Providing power to machine components is a fundamental aspect of machine design rather than a specific function of the control system itself. Similarly, the installation of cutting tools is typically a manual process handled by operators and does not involve the control system's main function. Thus, the interpretation of program code and the direct control of machine operations are indeed the core responsibilities of the CNC control system.
