TABLE ROTATING CONTROL DEVICE AND METHOD OF MACHINING CENTER

摘要

According to the present invention, when the numerical value control part of the machining center has the most advanced command of the table, the workpiece fixed to the table can be rotated to the maximum by reading the current position of the table and controlling the table to move to the center on the horizontal axis of the table. The present invention relates to a table rotation control device of a machining center and a control method thereof, which allow rotation without interference even when the radius is exceeded. An operation panel 31 for giving a rotation command of the table 30 and a servo motor 32 for table rotation are provided. In the table rotation control apparatus of a machining center composed of a motor driver unit 33 for driving a large workpiece, a large workpiece discrimination means 34 for detecting whether or not a large workpiece is applied, and from the large workpiece discrimination means 34. Input interface circuit 35 for receiving the input signal through the input and output port and the large workpiece discrimination means 34 When a large workpiece is detected by a signal input from the table, the table 30 is moved to the center of the table horizontal feed axis X2, and then the table rotation servo motor 32 is rotated to rotate the table 30 to an initial position. It is composed of a numerical control unit 40 to return to.
