METHOD AND GENERATOR FOR ELECTRICAL DISCHARGE MACHINING

摘要

PROBLEM TO BE SOLVED: To provide a method and a generator for generating discharge pulses with various types of different waveforms. SOLUTION: This method and the generator for generating a time sequence of discharge pulses separated from each other by pulse pauses for electrical discharge machining. At least two pulse capacitors 22 are discharged each in the form of a partial pulse into the spark gap for forming together a discharge pulse. A discharge pulse having a predetermined waveform is selected from a plurality of discharge pulses having differing predetermined waveforms. The discharge of the at least two pulse capacitors 22 is controlled such that the selected discharge pulse is generated with the predetermined waveform. COPYRIGHT: (C)2007,JPO&INPIT
