摘　　要：讨论了大型轧钢机辊子工件外圆磨削提高形状精度问题。从原始形状误差的付里叶级数表达式入手,分析了固定支承配置方式,工件在磨削点处相对砂轮的移动规律,为确定余量计算了辊子廓形中心坐标及砂轮中心相对辊子中心的坐标,采用4种方案进行实验模拟,得出了当支承配置角φz=φy=45°,砂轮工件中心连线与水平线夹角φk=90°时,磨削后辊子形状误差最小,辊子修复时,φz=φy=105°,φk=55°,φy=15°为最佳磨削条件。The problem how to improve the round outside accuracy of the large mill roller has been discussed .The fixing sustain mode and the motion principle of the element relative to the grinding wheel have been obtained by using the contour error Fourier series. Roller contour centre coordinates and grinding wheel centre coordinates relative to roller centre have been computed in order to determine allowance .The condition for minimal roller contour error and the optimal grinding position have been concluded by four kinds of analog experiments.
