摘　　要：针对三维超声辅助磨削加工方法的研究,建立砂轮磨粒切削运动模型,推导单颗磨粒切削轨迹方程,通过仿真分析二维和三维超声辅助磨削单颗磨粒切削轨迹,初步得出三维超声辅助磨削有望得到更优的表面质量。通过三维超声辅助磨削加工试验并观测陶瓷试件的表面粗糙度和微观形貌,证明三维超声辅助磨削的陶瓷表面粗糙度值相对较小,表面轮廓相对平整,三维超声辅助磨削能得到比二维超声辅助磨削更优的表面质量。Aiming at the research of three-dimensional ultrasound-assisted grinding method,a grinding wheel abrasive cutting motion model is established,and the equation of single abrasive cutting trajectory is deduced.Through simulation and analysis of two-dimensional and three-dimensional ultrasound-assisted grinding single abrasive cutting trajectory,it is preliminarily concluded that three-dimensional ultrasound-assisted grinding is expected to obtain better surface quality. The surface roughness and micro-morphology of ceramic specimens were observed and analyzed by three-dimensional ultrasound-assisted grinding. It was proved that the surface roughness value of three-dimensional ultrasound-assisted grinding was relatively small and the surface profile was relatively flat. Three-dimensional ultrasound-assisted grinding could obtain better surface quality than two-dimensional ultrasound-assisted grinding.
