  • Method for adaptive feed rate regulation on numerically controlled machine tools
    Patent number: 7346423
    Abstract: In a method for the adaptive feed rate regulation on a numerically controlled machine tool, which is used for the metal-removing processing of workpieces using a tool rotating on a spindle according to the specification of an NC program, the input power of the spindle is held as constant as possible by the influence of a tool feed rate established in the NC program for the motion between the tool and the workpiece. The method for the adaptive feed rate regulation is activated by a command of the NC program that initiates the processing of the workpiece, and is deactivated by a command of the NC program that terminates the processing of the workpiece.
