In order to realize feed rate of 20 m/min for cutting operation of medium and large size machine tools, a new high speed and high accuracy feed drive system which has a servo motor and ballscrew combined with a hydraulic actuator has been developed. The previous paper made clear that this system is possible to drive ten times as fast as conventional rate with considerably good accuracy. This paper describes a method for determining optimal PI control parameters of the electric servo motor and PD control parameters of the hydraulic actuator. In order to make the best use of the hydraulic actuator a new function which compare the force of electric servo motor with that of hydraulic actuator is proposed. The experimental results show that the controlling parameters determined by this method reduce motor power and the method is proved to be effective.
