摘　　要：为改善砂轮的磨削性能,将有序排布理论引入到电镀砂轮磨粒排布中。分别探讨了叶序、错位、无序排布砂轮在不同磨削参数下对工件表面粗糙度的影响,同时建立叶序、错位、无序排布电镀砂轮磨削表面粗糙度数学模型,并利用MATLAB软件进行仿真。在砂轮缓进给磨削过程中,叶序排布砂轮所获得的工件表面粗糙度值低于其他排布方式的砂轮。且工件表面的粗糙度值随着磨削速度比的增大而减小,随着磨削厚度的增大而增大。这为实际磨削工件表面粗糙度分析提供了很好的辅助和验证方法。In order to improve the performance of grinding,the ordered theory was introduced into the design of the wheel.Meanwhile the mathematical model of grinding surface roughness was established. The influence of grinding wheel with phyllotactic,staggered and disordered pattern on surface roughness has been discussed in different parameters,and simulated by the MATLAB software. In the process of creep feed grinding,the phyllotactic parameters can obtain lower surface roughness value and better surface performance of workpiece compared with other patterns. The workpiece surface roughness values decrease with the increase of grinding speed ratio,and increase with the increase of grinding depth. It will provides a supplementary and supervised method for analyzing the surface roughness of workpiece.
