难加工材料的超声电火花线切割复合加工工艺研究

Study on the processing of difficult-to-machine matericals by combined technology of ultrasonic and WEDM

开发了一种超声电火花线切割复合加工装置。加工中电极丝可产生横向振动 ,且振动方向始终与切割方向一致。对难加工材料的切割实验表明 :复合工艺能较大幅度地提高加工效率 ,改善表面质量 ,降低断丝概率。

A new kind of device has been developed, by which hybrid technology of ultrasonic and WEDM is performed. In operation, the transverse vibration of wire takes place and it can trace the cutting direction. The cutting experiments for difficult to machine materials have shown that the cutting rate can be increased much more, the surface quality improved and the probability of wire breaking reduced.
