【摘要】 通过研究高速走丝电火花线切割机床电极丝动态特性对多次切割的影响,分析了干扰电极丝动态稳定性的各种不利因素。多次切割结果表明,在具备一定传动精度和辅助设施如恒张力、限幅器等改进型机床上,采用适当的切割工艺,多次切割是完全可行的。更多还原

【Abstract】 By studying the effects of the wire dynamic stability of WEDM-HS (Wire cut Electric Discharge Machine with High travelling Speed) on the state of multiple cut machining, the author comprehensively analysed the unfavourable factors affecting on wire dynamic stability. After some improvement measures taken in the expeiment the multiple cut results show that, by using suitable cutting technologie, smultiple cut is feasible on the machine with high precision and other supplementary equipments such as guide, wire tension unit, etc.更多还原
