Abstract

PURPOSE: To perform tool replacing operation smoothly by a machine tool with a function of replacing a tool, by deciding upon the stable region and unstable region of a position control system by using a resolver of a two-phase output type for position detection.
CONSTITUTION: In tool-replacing operation, speed control system SCS is changed over to position control system PCS, which provides the orientation (ORI) operation of spindle 2. Output E2 of resolver 7A is converted into decision signal voltage E3 by decision signal forming circuit 7E. When the control system is within the stable region (E3=0), contact 10 is made to alternate the ORI speed control system with the ORI position control system. The position of the spindle at that time is converted by resolver 7A into electric signal E1 to turn motor 5C to a stable point and the spindle is stopped. The ORI operation is in effect only within the stable region, tool replacing operation can smoothly be performed.
