Abstract

PURPOSE:To carry out stop position servo with high precision by a method wherein positions of a working electrode are detected in digital amounts and stop positions for the working electrode are controlled on the basis of the digital amounts. CONSTITUTION:Displacements of a working electrode 1 are detected by the scale body 13 and the detecting head 14 on a digital measuring machine and input into a positional servo control circuit 15. This input signal is changed into pulses by a discriminating circuit 17 and the direction is discriminated and the pulses are counted by an arithmetic counter 18. The contents of the arithmetic counter 18 is converted into analog quantity by a D/A converter 19 and then amplified in an amplifying circuit 20 and transferred to a hydraulic servo valve 6. As a result, the current running through the hydraulic servo valve controls a hydraulic cylinder 5 so that the displacement of the working electrode 1 or the contents of the arithmetic counter 18 can take nothing.
