<p>A numerical control device for wire discharge machining equipped with a taper machining correction feature is provided so that accurate taper machining can be performed even when vertical displacement delta occurs in the effective support positions P1 and P2 of the wire guides 1 and 2 due to rigidity of the wire electrode 3. Theoretical wire inclination angle phi is calculated based on horizontal wire movement command u, and vertical displacement delta corresponding to the inclination angle phi is determined. Correction quantities necessary to eliminate displacement delta are determined, based on displacement delta and inclination angle phi , and correction quantities epsilon are distributively output to wire guides, thereby causing wire inclination angle to coincide with command inclination angle phi . <IMAGE></p> |
