摘　　要：针对双端面磨削中高精度与高效率难以同时实现的问题,以上砂轮磨削面形貌为研究对象,建立了修整后的上砂轮磨削面坐标方程,分析了工件磨除量在磨削区内的分布。分别建立了下砂轮坐标系、修整坐标系和上砂轮坐标系,通过空间几何坐标变换和MATLAB软件仿真,绘制了上砂轮磨削面的Z向坐标沿砂轮半径方向的变化曲线、上砂轮磨削面内任意点到下砂轮磨削面的距离随工件转角的变化曲线,分析了上砂轮磨削面的不同形貌对双端面磨削加工精度及精度保持性的影响。实验结果与计算分析吻合,验证了计算分析的正确性。Precision and efficiency can＇ t be both high in double disc grinding, regarded the upper grinding wheel surface topography as the research object, established the coordinate equation of grinding surface of the upper grinding wheel after dressing, analysed the distribution of machining allowance in grinding zone. With the simulation of MATLAB, presented the curve of topography profile about radius, the curve of the distance between the grinding surfaces of grinding wheels in the workpiece moving track. Analysed the effects of different topography on precision and the ability to maintain precision of double disc grinding machining. The experimental datas are conformed to the results of MATLAB simulation, verified the correctness of analysis results.
