Title:
ELECTRICAL DISCHARGE MACHINING APPARATUS AND ELECTRICAL DISCHARGE MACHINING METHOD
Document Type and Number:
WIPO Patent Application WO/2011/125656
Kind Code:
A1
Abstract:
Disclosed is an electrical discharge machining apparatus provided with a machining electrode (2) consisting of a wire which is wound around an assembly comprising a plurality of guide rollers (7a - 7d), thereby having a plurality of facing sections (2a - 2j) with respect to an article being machined (1); drive means (3, 6) which change the relative distance between the article being machined (1) and the facing sections (2a - 2j); and a plurality of pulse generation means (4a - 4j) which separately apply electrical discharge machining pulses between the article being machined (1) and the facing sections (2a - 2j). The plurality of pulse generation means (4a - 4j) are controlled so that the start time for the applying of electrical discharge machining pulses will not be the same for any two adjacent facing sections among the facing sections (2a - 2j).
