Title:
WIRE ELECTRO-DISCHARGE MACHINING DEVICE
Document Type and Number:
WIPO Patent Application WO/2011/049101
Kind Code:
A1
Abstract:
Disclosed is a wire electro-discharge machining device which uses a wire electrode (8) to machine a workpiece (7) into a product, the workpiece (7) having varying thickness. The wire electrode (8) moves on a tool path (Q) where a product profile (P) is offset in an offset direction. The wire electro-discharge machining device comprises a step position estimation means (21) for performing an operation wherein a step position where the thickness of the workpiece (7) changes abruptly is estimated on the basis of three-dimensional shape data of the product, resulting in an estimated step position (Ps) being generated. Furthermore, the wire electro-discharge machining device comprises a step position detection means (37) for detecting the actual step position (Qs) of the workpiece (7) during machining of the workpiece (7), and a step position correction means (38) for correcting the estimated step position on the basis of the actual step position.
