Abstract
A feed control method for wire cutting electrochemical discharge machining is disclosed. The method determines whether a contact event has occurred using a wire electrode, based on variations in wire tension when being cut. A wire is cut with an ideal feed speed when the wire electrode is not in contact with a workpiece.
