摘要：
A copying-speed control method for an NTC copying which performs profile control of one axis and numerical control of the other two axes. In the servo loop of the numerical control axis, an override control circuit (23) is provided between an error counter (22) and a D/A converter (16x). When a displacement changes abruptly the override value of the override control circuit is changed to stop or reduce the servomotor output of an error quantity in the error counter (22). Thereby, the biting at sudden changing parts of a model is reduced.
