摘　　要：本文通过不同振动模式下的Al2O3工程陶瓷普通与超声研磨对比试验,利用正交回归分析方法获得了最优研磨参数,探讨了各研磨参数对工件表面粗糙度影响的主次顺序。并分析研究了工件转速、进给速度、油石粒度、研磨切深、发生器功率等不同研磨参数对表面粗糙度的影响规律。结果表明,超声振动研磨可明显减小表面粗糙度值,提高工件表面质量,是适合工程陶瓷等硬脆材料的一种高效加工方法。In this paper,conventional and ultrasonic lapping experiments of Al2O3 ceramics with different vibration models under different lapping parameters were conducted.By the method of orthogonal regression analysis,the optimum lapping parameters are obtained and the significance order of the influecing factors on surface roughness is presented.At the same time,the influence rule of such different lapping parameters as rotational speed,feed speed,oilstone grit,lapping depth and generator power on surface roughness is studied.Experimental results show that with ultrasonic vibration lapping,the surface roughness value can be obviously reduced and the surface quality of workpiece can be increased,therefore,ultrasonic vibration lapping is a high efficient processing method for hard-brittle materials.
