摘要： PROBLEM TO BE SOLVED: To provide an electrical discharge cutting device which is simple in structure and improved in working efficiency of electrical discharge cutting.
SOLUTION: In implementation of the electrical discharge cutting, an inter pole voltage between an electrode and a workpiece to be cut is measured, and if the measured inter pole voltage is equal to or smaller than a predetermined value, the electrode is retreated (S5), followed by measuring a retreated distance of the electrode. If the measured retreated distance of the electrode is smaller than a predetermined value, retreat of the electrode is stopped (S7), and the retreat of the electrode is halted over a predetermined time (S8). Thereafter the inter pole voltage of the electrode is measured again, and if the re-measured inter-pole voltage is larger than the predetermined value, the electrode is moved forward. On the other hand if the re-measured bathvoltage is equal to or smaller than the predetermined value, the electrode is further retreated (S9). In this manner a retreating distance of the electrode is minimized, and an electrical discharge cutting period of the workpiece to be cut is minimized, to thereby improve the working efficiency of the electrical discharge cutting.
