ABSTRACT:
In an electrical discharge machining apparatus having a nose guide (12) and an electrode datum (26) movable relative to one another, a cartridge (14) movable relative to the nose guide, a plurality of substantially parallel electrodes (16) supported by the nose guide (12) and the cartridge (14) and a cartridge clamp (32) engageable to prevent relative motion between the electrodes (16) and the cartridge (14), a method of refeeding and realigning the electrodes between machining operations compensates for erosion. In this method, the separation of the datum (26) from the nose guide (12) and cartridge (14) is decreased while protruding electrodes that engage the datum are received back into the cartridge. Because the nose guide and cartridge remain in fixed relation at that stage there is no need for a friction pad between the cartridge (14) and the electrodes (16). The electrode datum may be a surface of the workpiece that is to be machined.
