摘　　要：超声研磨能有效提高研磨效率,使工件获得较高的尺寸精度和微观几何形状精度。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优选工艺参数和经验公式,得出了各工艺参数对研磨压力的影响主次顺序,并分析了各工艺参数对研磨压力的影响规律。结果表明:超声研磨所获得的研磨压力低于普通研磨,且轴向研磨压力要小于切向研磨,超声复合研磨是适合工程陶瓷等硬脆材料的一种高效加工方法。Ultrasonic vibration lapping can effectively improve the lapping efficiency and obtain higher dimension and micro-geometry precision. Based on the contrast experiment on common lapping and ultrasonic lapping with dif- ferent vibration models and lapping parameters, the empirical formulas for calculating ultrasonic lapping pressure were derived by means of orthogonal regression analysis, the optimal processing parameters were put forward, and the important or less important influence and the order of influence of parameters on lapping pressure were presen- ted. Moreover, the influence of different lapping parameters on lapping pressure was analyzed. The experimental results show that the lapping pressure exerted by ultrasonic vibration lapping is less than that by common lapping and that the axial pressure is minimum. Therefore, ultrasonic vibration lapping is a highly efficient processing method suitable for hard and brittle materials.
