利用电火花线切割机加工上下异形件的工艺研究

Technics Research of Using WEDM Tool to Machine Up and Down Abnormities Parts

为拓展快走丝数控线切割机床的加工范围,从电火花线切割机床的四轴双坐标面的运动控制描绘了切割电极丝倾斜运动的基本原理,认真探讨了复杂的上下异形工件在切割加工中的关键问题,摸索出影响异形件精度的2个重要参数的确定方法,细致介绍了上下异形件从编程至切割加工的主要过程。

For developing machining range high speed NC WEDM tool. The basie principle of eut electrode wire inclined is reflected through movement eontrol of four axles both eoordinates of WEDM tool, and the key problems of the up and down abnormities parts in eutting process is partieularly discussed, and caleulation means of affecting both important parameters of abnormities parts precision is groped. The main process of the up and down abnormities parts is partieularized from programming to eutting machining.
