摘要
Aiming at the problems of high cutting force, high cutting temperature and severe tool wear during the cutting process of GH4169 superalloy,electroplastic assisted milling experiments were performed to study the influence law of pulse current on average cutting force,cutting temperature and tool wear. The results show that pulse current can effectively reduce the average cutting force in the milling process, and the average cutting force along Z-axis direction changes significantly when the cutting depth is 0.2-0.4 mm. When the current density is 4.08 A?mm-2, the average cutting force along Z-axis direction is decreased by 29.2% compared with that without current. At a certain current density, the pulse current can effectively reduce the cutting temperature in the milling process; pulse current can effectively alleviate the speed of tool wear, when the current density increases from 4.08 A?mm-2 to 17.13 A?mm-2, the average wear width of rear tool surface is decreased by 15.5% and 38.1% respectively compared with that without current.
