Abstract

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
