ワイヤ放電加工の加工シミュレーション -第1報 解析方法と解析例- Simulation of Wire EDM(1st Report) -Simlating Procedure and Examples-
Precisions of Wire-EDM are spoiled by a wire deflection and a wire vibration during the machining. Examples, these wire behaviors cause a smoothed corner or a smaller radius corner shape and a concave cut wall.<br>As well known, these wire behaviors are caused by a explosive pressure, a electrostatic force, a electromagnetic force by each discharge and a force caused by flushing of water during Wire-EDM.<br>In previous some papers, wire behaviors are measured and discussed. And other papers reported methods to solve problems of cutting precisions.<br>But in spite of these reports, wire behaviors and the influence of EDM conditions on them are not so cleared, also the relation between cutting accuracy and wire behaviors is not so well understood yet.<br>For these investigations, simulations of Wire-EDM will be useful. But the simulation of Wire-EDM is quite different from them of conventional EDM because all process and repetition from voltage supply to discharge, explosion, machining and wire movement should be considered.<br>In this report we mainly describe a simulating procedure and few nalyzed results of Wire-EDM.
