【摘要】 针对型孔尺寸精度、表面粗糙度及型孔分布圆轴心线与工件外圆柱面轴心线的同轴度有较高要求的多型孔零件,从切割路线及切割次数的安排、电极丝偏移量的计算、穿丝孔位置及切入切出方式的确定、工作液及电参数的选择、工件装夹与调整、程序编制、加工及检验等方面进行研究,形成了完整的型孔加工工艺和检验方法,实践证明效果良好。更多还原

【Abstract】 After studying the parts with which demand high dimension precision,surface roughness,the Coaxial degree of part outline with location of the seed cells,as well as considering arrange of incise routine,incise times,calculation of eccentric traveling distance for electrode-wire on WEDM,determination of location for wire hole and way for cut-in and cut-out,choice of coolant and electric parameters,adjustment and workpiece configuration,programming,processing test,the processing technics and test measurement were come into being at last,and it turns out works well practically.更多还原
