高速走丝线切割机床改造及多次切割加工试验研究

Research on multi-cutting in HSWEDM

利用模具钢Cr12样件,用高速走丝线切割机床进行多次切割试验研究,结果表明,采用多次切割能提高切割精度和表面质量。同时提出高速走丝线切割机床进行多次切割工艺时存在的问题和前提条件,并阐述了多次切割的理想工艺参数。

Did many experiments for multi-cutting in High Speed Wire EDM （HSWEDM） and molding tool steel Cr12. It ex- pressed that multi-cutting can raise the cutting accuracy and surface quality. And put forward that the problems and prior condi- tions of HSWEDM, and elaborated that the idea pulse parameters for HSWEDM.
