Title:
NUMERICAL CONTROL SYSTEM
Document Type and Number:
Japanese Patent JPS5880706
Kind Code:
A
Abstract:
PURPOSE:To control plural control shafts by means of a servomotor and a servocontrol circuit, by providing a servomotor and a servocontrol circuit to each control shaft and then giving a control command from a position command part. CONSTITUTION:The servocontrol circuits 213-215 of X, Y and Z shafts are provided to the X, Y and Z shafts of a machine tool respectively. At the same time, a servocontrol circuit 216 common to U and W shafts is provided to the circuit 216. Then pulse train acceleration/deceleration circuits 210U and 210W are connected to the circuit 216 via a changeover switch 218. This switch 218 is controlled with the output of a U/W switching control circuit 219 which uses a command given from a manual control circuit 219 which uses a command given from a manual control board 205 as an input. The U and W shafts are switched by a motor 217UW. Thus the constitution is simplified for a numerical controller of a machine tool.
