Wire electric discharge machine and automatic programming device for wire electric discharge machine

摘要

In a wire electric discharge machine or an automatic programming device for a wire electric discharge machine, in which a core is held with a workpiece base material by attaching brass contained in a wire electrode to the machining groove during machining, an attachment/deposition region where machining chips containing brass produced during machining are attached and deposited to the workpiece is set based on a machining shape obtained from a machining program and the machining chips containing brass produced during machining are attached and deposited according to the set attachment/deposition region.

主权项

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.
