摘要: 基于电致塑性效应和滑动电接触原理,电脉冲辅助切削能够改善金属材料的塑性变形行为和摩擦学状态,而螺旋铣孔作为一种高效制孔工艺,能够一次成形大直径孔。针对钛合金高效钻孔需求,提出电脉冲辅助螺旋铣孔加工方法,对比研究了有无电脉冲辅助的螺旋铣孔刀具磨损与加工性能,揭示了脉冲电流参数对切削力、切削温度、表面粗糙度和孔径精度的影响规律。试验结果表明,电脉冲辅助螺旋铣孔表面粗糙度比普通螺旋铣孔降低了23.1%,刀具磨损下降了大约20%,孔径的精度也大幅度提升。证实了电脉冲辅助螺旋铣孔能够有效用于钛合金高效钻孔加工。

Abstract: Electric pulse assisted cutting can improve the plastic deformation behavior and tribological state of metal materials based on electroplastic effect and sliding electric contact principle. As a efficient technique for making holes, helical milling can form large aperture holes. An electric pulse assisted helical milling method is proposed aiming at the requirement of high efficiency drilling of titanium alloy, the tool wear and machining performance of the helical milling with and without electric pulse assisted are compared, and the influences of pulse current parameters on cutting forces, cutting temperature, workpiece surface roughness and aperture accuracy are revealed. The results show that the workpiece surface roughness of electric pulse assisted helical milling is reduced by 23.1% compared with ordinary helical milling, the tool wear is reduced by about 20%, the aperture accuracy is also greatly improved, it is proved that electropulse assisted helical milling can be used for high efficiency drilling of titanium alloy.

Key words: electric pulse assisted helical milling, titanium alloy, large aperture hole, tool wear, aperture accuracy
