Abstract

PURPOSE:To eliminate a machining error, when a linear tool performs cutting, by detecting flexion of the linear tool due to its machining reaction force and correcting a machining feed amount by the amount of said flexion. CONSTITUTION:In cutting work by a linear tool at wire cut electric discharge machining, abrasive grain wire machining, etc., a wire 2 is flexed by machining reaction force by a flexion amount t. Flexion of the wire 2 is detected by flexion detectors 7, 8. The flexion detectors 7, 8 are, for instance, optically constituted in such a manner that parellel beams of light are irradiated to the wire 2 from each direction X, Y, and the displacement is detected by a photocell unit 6. From this detection, the flexion amount t is calculated, and a machining table is corrected its machining feed amount by the flexion amount t, thus a machining error can be eliminated.
