ABSTRACT:
A method of calculating an amount of offset for a wire electrode in a wire cut electric discharge machining operations. The offset amount for each of machining steps from coarse machining to finish machining are calculated with reference to a data table including a plurality of offset data each including a combination of a first machining margin to be removed by the wire electrode per se and a second machining margin to be removed by an electric discharge. The method is capable of reducing the number of data required for determination of the offset amounts for plural machining steps.
