Claim of US Patent No. 9,085,037

1. A wire electrical discharge machine for machining a workpiece, the wire electrical discharge machine comprising:
at least one wire guide configured to move a wire electrode with respect to the workpiece to machine the workpiece by discharge
generated between the wire electrode and the workpiece; and

a numerical controller configured to cause the wire guide to relatively move the wire electrode with respect to the workpiece
while inclining the wire electrode within a plane parallel to a machining surface to which the wire electrode approaches in
an approach section, wherein

the wire electrode performs cutting machining on the machining surface of the workpiece, and
after the approach section, the numerical controller is configured to cause the wire guide to gradually reduce an inclination
of the wire electrode within the plane parallel to the machining surface for performing machining on the machining surface.
