Claim Text:
1. A wire electric discharge machining method for moving a wire electrode relative to a workpiece according to a machining program and machining the workpiece into a desired target shape, the method comprising the steps of: analyzing the machining program; creating a target shape for the workpiece based on a result of analysis of the machining program; storing an amount of wire radius compensation for the wire electrode; setting a plurality of amounts of wire radius compensation adjustment by which the amount of wire radius compensation for the wire electrode is adjusted; storing the plurality of amounts of wire radius compensation adjustment that have been set; selecting one or more desired amounts of wire radius compensation adjustment from the stored amounts of wire radius compensation adjustment; computing an amount of wire radius compensation for machining route calculation by adding the selected amounts of wire radius compensation adjustment to the amount of wire radius compensation; creating a machining route which is offset from the created target shape by the computed amount of wire radius compensation for machining route calculation; and moving the wire electrode relative to the workpiece according to the created machining route.
