摘　　要：为降低传统快走丝线切割机加工表面粗糙度,对其采用旋转+往复直线运动的新型复合运丝工艺,通过分析快速旋转+往复直线运动的复合运丝形成的电火花磨削加工效应,将钼丝单边损耗转化为圆周损耗,降低了加工中钼丝偏移补偿量影响。使用电火花磨削加工工艺,改善了线切割加工中的排屑条件,消除了工件加工表面的换向条纹。试验结果表明,复合运丝工艺可明显提高加工精度并降低表面粗糙度。In order to reduce the surface roughness value of traditional fast wire cutting machine,a new composite wire conveying process is adopted for it.By analyzing the effect of EDM grinding formed by rapid rotation+linear wire conveying,the unilateral loss of molybdenum wire is changed into circumferential loss,and the effect of molybdenum wire offset compensation is reduced.Due to the use of the electric grinding process,the chip removal conditions in the processing are improved,and the reversing stripes on the workpiece surface are eliminated.The test results show that the composite wire handling can significantly improve the machining accuracy and reduce the surface roughness.
