摘      要：Inconel718 was machined with the traditional micromilling(TMM)and ultrasonic vibration assisted micromilling(UVAMM)with the different technology parameters,whose surface quality and burrs formation were *** results show that TMM often forms pits,bumps and gullies in the size effect *** effectively improves the surface quality compared with *** surface defects are significantly reduced with the increase of feed per tooth(fz).When fz exceeds 4 lm,the effect of ultrasonic vibration on the surface quality is no longer *** minimum burr size on the down milling side and the up milling side are 50.23 lm and 36.57 lm,*** feasibility of vibration cutting in improving surface quality and suppressing burr size was *** effectively suppresses the formation of built-up edge,which can significantly improve the micromilling *** cutting force is obtained through simulation and *** are agreement in the change *** finite element simulation can be used to predict the cutting *** with TMM,feeding force(Fx),radial force(Fy)and axial force(Fz)of UVAMM decrease by 7.6%,11.5%and 1.3%,respectively.
