Abstract
Official abstract text for this publication.
The present invention includes drive units 7 a and 7 b that change a relative position between a wire electrode 12 and a workpiece 14 by moving a position of wire guide 8 a and 8 b , drive control units 6 a and 6 b that drive the drive units 7 a and 7 b based on a machining shape on the workpiece 14 , respectively, a correction-amount storage unit 3 that previously stores therein a position correction amount for the wire electrode 12 corresponding to a machining condition, a correction-amount reading unit 4 that reads the position correction amount corresponding to the machining condition from the correction-amount storage unit 3 , and a wire-position correction unit 5 that causes the drive control units 6 a and 6 b to correct a relative distance between the wire electrode 12 and the workpiece 14 based on the read position correction amount.
First claim
Opening claim text (preview).
The invention claimed is: 1. A wire electric discharge machining apparatus comprising: a first wire guide that supports a wire electrode at a first position and delivers the wire electrode to a side of a workpiece; a second wire guide that supports the wire electrode at a second position opposing the first position and rewinds the wire electrode delivered from the side of the workpiece; a first drive unit that changes a relative position between the wire electrode and the work…
