X-Y平面联动的平面研磨轨迹分析与研磨实验
Experimental Study of X-Y Linkage Plane Lapping Track

针对传统研磨方法的研磨轨迹覆盖均匀性等问题，开展了X-Y联动的平面研磨轨迹仿真与实验研究。建立了该X-Y联动的平面研磨轨迹运动模型，仿真分析了初始向径、初始相位角、转速比、X-Y联动轨迹等参数对研磨轨迹的影响规律；在自主研发的样机平台上开展了研磨实验研究。对试件研磨表面的平面度与粗糙度进行检测，验证了研磨轨迹曲线仿真方法的有效性，表明良好的研磨组合参数是提升研磨表面质量的必要因素。
Some problems of coverage uniformity last for a long time in the traditional plane lapping, simulation and experiments are carried out to investigate the X-Y linkage plane lapping track, whose motion model is established. Effects of four parameters on the lapping trajectory are simulated, including initial diameter, the phase angle of initial point, speed ratio and X-Y linkage plane lapping track. Then, experiments on the plane lapping are conducted for a self-developed plane lapping machine tool. The flatness and roughness of its lapping surface are measured. The experimental results ensure the effectiveness of the lapping trajectory simulation method and show that the reasonable combination of lapping parameters is an essential factor for improving the surface quality
