Abstract
A method for controlling a wire electrical discharge machining (WEDM) process, in which the wire traveling speed VW is adapted in-process, while cutting. The method includes, determining the size of the crater occurring at each said determined position of each discharge along the engagement line of a wire and a work piece, and the current wire traveling speed; and continuously comparing the wire wearing model with one or more wire wearing limits, and adjusting the wire traveling speed according to the comparison of the actual wire wearing model and the one or more wire wearing limits. The wire electrical discharge machining process is conducted with reduced wire consumption, safely, efficiently and profitably.
