WIRE ELECTRIC DISCHARGE MACHINE AND MACHINING PASS GENERATING APPARATUS FOR WIRE ELECTRIC DISCHARGE MACHINE

摘要

A key groove is cut in the center along a machining route with a wire electrode and machined to a key bottom surface of the key groove. When the machining reaches the key bottom surface of the key groove, the key groove bottom surface is machined to the left in the figure. When the machining reaches a key groove side surface, the key groove side surface is machined toward a key groove inlet. Subsequently, the key groove is cut in the center along a machining route to be machined to the key groove bottom surface of the key groove. When the machining reaches the key groove bottom surface of the key groove, the key groove bottom surface is machined to the right in the figure. When the machining reaches a key groove side surface, the key groove side surface is machined toward the key groove inlet.

主权项

1. A machining pass generating apparatus for a wire electric discharge machine configured to generate a machining pass for machining a key groove on a side surface of a round hole,
the machining pass generating apparatus comprising: a key groove defining unit configured to define a shape of the key groove to be machined; a hole diameter designating unit configured to designate a diameter of the round hole; a hole position designating unit configured to designate a position of the round hole; and a machining pass generating unit configured to generate a machining pass, the pass suppresses an opening of the key groove from being narrowed.
