摘　　要：为优化球轴承内圈沟道精密磨削过程,确定最优磨削参数组并构建表面粗糙度预测模型。研究通过沟道正交和单因素试验系统分析磨削深度、砂轮线速度和工件转速对表面质量的影响,根据极差和方差分析确定最优参数组,并利用多元回归经验公式拟合表面粗糙度预测模型。结果表明,表面粗糙度随磨削深度和工件转速的增加而增大,随砂轮线速度的增加而减小,影响程度为磨削深度>砂轮线速度>工件转速。确定最优参数组为磨削深度10μm、砂轮线速度46 m/s和工件转速300 r/min。为改善沟道表面形貌,应适当减小磨削深度和工件转速,同时避免砂轮线速度过高。此外,经误差检验验证后的表面粗糙度预测模型,可为沟道精密磨削参数优化和表面质量提高提供理论依据。To optimize the precision grinding process of the ball bearing inner ring groove,determine the optimal grinding parameter combination,and construct a surface roughness prediction model.The study systematically analyzes the effects of grinding depth,wheel linear velocity,and workpiece rotational speed on surface quality through orthogonal experiments and single-factor tests.Based on the results of range analyses and ANOVA the optimal grinding parameter combination is determined,and by multiple regression experience formulas to fit the surface roughness prediction model.The results indicate that the surface roughness increases with the increase of grinding depth and workpiece rotation speed and decreases with the increase of grinding wheel linear speed,and the influence degree is that the grinding depth is greater than the grinding wheel linear speed,followed by the workpiece rotational speed.The optimal parameter combination is determined to be a grinding depth of 10μm,a grinding wheel linear speed of 46 m/s,and a workpiece rotational speed of 300 r/min.To improve the surface morphology of the raceway groove,it is advisable to appropriately reduce the grinding depth and workpiece rotational speed,avoiding excessively high grinding wheel linear speed.In addition,the surface roughness prediction model verified by error test,while can provide the theoretical basis for the optimization of precision grinding parameters and the improvement of surface quality.
