What is a control system for machine tools?
Following the invention of Computer Numerical Control (CNC) in the early 1970s, many companies started to develop their control systems for machine tools. The control system typically includes motors, amplifiers, switches, and the controller.
How does a CNC cutting tool controller work?
After this origin is located, the zero position is communicated to the machine tool operator for the cutting tool to be moved under manual control to some target point on the worktable, where the tool can be easily and accurately positioned. The most basic function of any CNC controller is automatic, precise, and consistent motion control.
What is a CNC machine control unit (MCU)?
In today鈥檚 CNC technology, the machine control unit (MCU) consists of some kinds of computers with related control hardware that store and sequentially execute the program of instructions by converting each command into mechanical actions of the processing equipment. The general configuration of the MCU in a CNC system is illustrated in Fig. 4.13.
