摘　　要：为了研究凸轮磨削加工过程中砂轮架导轨直线度误差对凸轮廓形精度的影响,首先建立了由于砂轮架导轨直线度误差引起的砂轮架中心位置坐标的偏移对凸轮磨削加工过程中引起的几何廓形误差数学模型,同时利用水平框式仪测量出砂轮架导轨在垂直度方向的直线误差偏移量,采用MATLAB8.0计算机软件编写相应的直线度误差和凸轮廓形廓形误差的计算程序,最后根据仿真结果分析砂轮导轨直线度误差对凸轮轮廓廓形误差的影响形式及大小。In order to study the influence of rail straightness error of grinding wheel rack guide on the accuracy of the profile shape of the cam in the process of cam grinding,the geometric profile error mathematical model is first established for the grinding wheel frame center coordinates offset caused by grinding wheel rack straightness error. At the same time,the level frame meter is applied to measure wheel frame rails in vertical direction of linear error offset,using MATLAB 8. 0 computer software programs to calculate the corresponding straightness error and the cam profile error. Finally, the influence in form and size of grinding wheel guide rail straightness error on cam profile error are analyzed based on the simulation result.
