Title:
ELECTRIC DISCHARGE MACHINING METHOD AND DEVICE
Document Type and Number:
Japanese Patent JP3808544
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To prevent a work from being strongly pressed by an electrode by performing electric discharge machining for a work by a pipe-like electrode, and stopping the feed of the electrode on detecting that the electrode is brought into contact with an insulator to stop electric discharge machining.
SOLUTION: When feed is given to an electrode 19, the electrode 19 is bent while being rotated, and a little bent to a V-shaped notch part 31 side in an oscillation preventing member 27 to come into contact with a sensor 35 of the inside edge. When the electrode 19 comes into contact with the sensor 35, the lower end part of the electrode 19 is brought into contact with an insulator WI to be detected as the occurrence of bending in the electrode 19, and the feed for the electrode by a servo motor 5 is stopped to stop electric discharge machining. Accordingly, it is possible to prevent the electrode 19 from being largely bent to be broken.
