WIRE ELECTRICAL DISCHARGE MACHINE AND WIRE ELECTRICAL DISCHARGE METHOD FOR REDUCING MACHINING DAMAGE DURING CUTTING MACHINING AND ESCAPE MACHINING
First Claim
1. A wire electrical discharge machine which relatively moves a wire electrode with respect to a workpiece according to a machining program and machines the workpiece by discharge generated between the wire electrode and the workpiece, the wire electrical discharge machine comprising:
- an approach control unit for relatively moving the wire electrode with respect to the workpiece, while inclining the wire electrode within a plane parallel to the machining surface to which the wire electrode approaches, in an approach section where the wire electrode performs cutting machining on a machining surface of the workpiece.

Abstract
A wire electrical discharge machine includes an approach control unit. The approach control unit relatively moves a wire electrode with respect to a workpiece while inclining the wire electrode within a plane parallel to the machining surface to which the wire electrode approaches, in an approach section where the wire electrode performs cutting machining on the machining surface of the workpiece.
