抄録

The dynamic characteristics of an NC Turret Punching Press has been evaluated by using the transfer function between the input command and the resultant carriage motion measured directly. The transfer function is decomposed into two units : one is control system, the other is mechanical one. Next, a new control method for the carriage motion has been developed by using the experimental transfer function. This method is based on the idea that an input-output relation between a control command and the resultant carriage motion can be described in a linearized form constructed by the transfer function measured at a representative position of a carriage. The control input which realizes a carriage motion to move with the desired trajectory and the rapid motion has been easily calculated by our method. The experimental results showed considerable surpression of the over shoot and the vibratory motion.
