Abstract

PURPOSE:To exactly correct a position of a moving body by a method wherein a measuring apparatus for measuring an expansion rate of the feed screw shaft is provided at one end of the feed shaft arranged in a vertical direction, whereby an extension caused by heat and expansion by a weight of the moving body are synthetically measured. CONSTITUTION:A ball screw shaft 1 regulated in moving in an axial direction at the top end of a carriage is pivotally rotatably supported in approximately vertical state. A tool rest 2 is moved up and down on the carriage by the rotation of the shaft 1. Further, the shaft 1 is coupled with an angle detector 5 by which a position of the tool rest 2 is detected, and the measuring apparatus 6 is mounted on the carriage relative to the bottom end of the shaft 1 and the displacement of the bottom end of the shaft 1 is measured to enable the extension of the shaft 1 to be measured. Accordingly, an electromotor is driven in such that an output of the detector 5 and an output of the measuring apparatus 6 are fed to an arithmetic unit 7 and a position command value of the carriage 2 fed from a command value resistor 8 to the arithmetic unit 7 is corrected to obtain the precise position of the carriage 2.
