摘　　要：研磨轨迹的均匀性决定球体的质量。应用图形坐标变换的方法,建立了四轴球体研磨机的轨迹数学解析方程,轨迹方程由24个方程组成。借助Matlab软件对研磨轨迹进行了模拟,轨迹模拟结果为包络整个球面。提出了用均匀度评价轨迹均匀性,均匀度与时间呈线性关系。为实际研磨的工艺参数选择提供重要理论依据。The lapping track uniformity decided the spherical quality. Four axis spherical lapping machine track mathematical analysis equation,the equation maded up of 24,is established using the graphic coordinate transformation method. Lapping track simulated using Matlab software ,trajectory simulation resulting in enveloping the entire spherical envelope. The track uniformity evaluation method proposed using evenness,to simulate a 20-minute evenness to 0.11,the uniformity of time and linear relation of evenness and time. The theoretical basis of actual lapping process parameters is provided.
