ABSTRACT:
A wire-cutting electric discharge machining device comprises a process precision detection device. The process precision detection device detects process error by measuring spacings between the wire electrode, which will be moved along a predetermined measurement path, and a processed edge of the workpiece, in which the measurement path is set substantially a parallel to a processed edge of the product. The process precision detection device measures the spacing between the wire electrode and the processed edge of the product by moving the wire electrode from a measurement point on the measurement path to the edge of the product while detecting electrical voltage between the wire electrode and the product.
