WIRE ELECTRICAL DISCHARGE MACHINING APPARATUS AND WIRE POSITION DETECTION METHOD

摘要

A wire electrical discharge machining apparatus (100) determines the position of a wire electrode (1) with respect to a workpiece (2) on the basis of the relationship of the inter-electrode distance, between the wire electrode (1) and the workpiece (2), with electrical data that changes according to the inter-electrode distance, and electrical data measured at a given inter-electrode distance.
