Claim of US Patent No. 9,199,326

1. A wire electric discharge machine which relatively moves a wire electrode containing brass and a workpiece in accordance
with a machining program to machine the workpiece by electric discharge produced between the wire electrode and the workpiece,
the wire electric discharge machine configured to:
obtain a machining shape from the machining program;
calculate a position of a center of gravity of the machining shape and set an attachment/deposition region in which machining
chips containing brass produced during machining are attached and deposited to the workpiece at intersections of two orthogonal
straight lines, each passing through the position of the center of gravity of the machining shape, with the machining shape;
and

attach and deposit machining chips containing brass produced during machining to the workpiece according to the set attachment/deposition
region.
