NC machine controller for N=axis control of machine tool - has multiple processors to handle specific functions of NC controlled machine tool

摘要

A numerically controlled machine tool system with n' axis capability has a central processor (4) that performs interpretation of the entered commands rebuting to the put programme, while another processor (5) interprets the data to generate incrementate commands to control the actuators of the system. The keyboard (2) and display (1) are controlled by a separator processor (3). Each axis (9) has a coupled position transducer (10) witha conditioning circuit (11) that generates square wave signals that are processed (12) with phase displaced commands to generate as analogue signal to control the servo drive motors the processor circuit for the phase shift operator is based upon counting stages.
