Abstract

PURPOSE:To make it possible to highly accurately perform the measurement of the work configuration and the position inspection by a method wherein the working electrode or the inspection electrode is made to face to the workpiece, a microvibration is applied to one, thereof, power is supplied therebetween in order to detect the contact state change at the gap control is so effected that said detection signal is constant at all times, and the vibration output is recorded or displayed. CONSTITUTION:A wire electrode 1 is vibrated by a vibrator 8. An inspection voltage is applied to the gap between the wire electrode 1 and a workpiece 11 by a power source 16, and the nearly contact state between the wire electrode 1 and the workpiece 11 is detected by a resistor 17 as a voltage signal. While the number of the vibrations N or energy E of the vibrator is being controlled by a control circuit 18 so that said voltage signal is kept constant, motors 13 and 14 are driven by an NC apparatus 15 in order to apply the relative movement control according to the configuration similar to that in machining between the wire electrode 1 and the workpiece 11. Said contact resistance is detected, and the signal of the result is applied to a head 20 to record it on a recording paper by means of a recording pen 21 for inspection of the machining position and accuracy.
