ABSTRACT:
A method for synchronously interlocking feed axes of a lathe is disclosed. In particular, a numerical controller (NC) controls the operation of a lathe by sending position command signals to servo amplifiers. The lathe turns a long workpiece chucked by two opposed headstocks which are driven synchronously. The servo amplifiers send signals to corresponding directional servo motors for moving the headstocks in respective directions. The present invention overcomes the problems of mechanical and workpiece displacement developed as loads on the servo motors by compensating for the positions of the feed axes by means of position offset values determined from the displacement of the machine or workpiece. Specifically, the displacements are detected in accordance with a difference between the torque of the two feed axes to be controlled for synchronous interlocking. In this manner, the displacement of the machine or workpiece is compensated for by moving the headstocks, which are synchronized in the corrected positions.
