Abstract

PURPOSE: To complete an unfinished portion of a work perfectly by a method wherein an electric discharge machining is effected by forcibly inserting an electrode into the work and the electrode is moved into a transversal direction thereof during a predetermined period of time after the electrode is arrived at a predetermined position.
CONSTITUTION: An electric discharge machining is effected by forcibly inserting an electrode 1 into a direction of a work 2. When the electrode 1 is forced into a predetermined position, an output of a differential transformer 13 becomes lower than a comparison voltage VB of a comparator 15 and an output of the comparator 15 becomes "1". Then, a monostable multivibrator 16 is operated during a predetermined period of time. A part of the work 2 remained without being worked yet is removed by the electrode 1 staying at a predetermined position and effecting a revolutional circular motion. When the staying time of the electrode 1 exceeds an operating time of the monostable multivibrator 16, an output of an AND gate 18 becomes "1" and is functioned to a pulse current generating device 3 as a signal indicating a finish of the working, thereby, a series of the operations is completed.
