Problems solved by technology

However, there is a problem that once the wire is long, it is easy to loosen, it is difficult to effectively control the short circuit, and the possibility of wire breakage is high.
In addition, in wire electric discharge machining, the surface accuracy and machining accuracy of the machined surface are important, but such machining accuracy has not been considered in the past

Abstract

A wire electric discharge machining device capable of machining a work under specified working conditions by using working fluid provided in a clearance between a wire and the work, comprising a machining condition storage means for holding machining conditions, a means for storing the relation between a nozzle height and a machining energy amount, a machining energy determination means for determining, for example, the machining energy amount in a rough machining based on the relation, and a machining condition alteration means for altering the machining conditions according to the machining energy amount, wherein the work is machined under the altered machining conditions, whereby a damage to the wire can be prevented and the accuracy of a machined surface can be increased.

Description

technical field [0001] The present invention relates to a wire electric discharge machining device. Background technique [0002] Generally, wire electric discharge machining is divided into rough machining, intermediate machining, intermediate finishing machining, and finishing machining, and machining is performed in three to seven steps while sequentially switching machining conditions from high energy to low energy. Its purpose is to shorten the processing time by gradually improving the smoothness of the processed surface, and to improve the straightness of the processed surface. Furthermore, as we all know, in wire electric discharge machining, the machining produces discharge repulsion, electrostatic force, etc., which cause the wire to vibrate, so that the wire part facing the center of the workpiece is depressed or swells, that is, it becomes "bulging". shape". In addition, in the wire electric discharge machining, the machining state is completely different in th...
