分析带有凹面轮廓的凸轮轴（简称凹面凸轮轴）数控磨削加工难点，提出采用大砂轮与小砂轮复合数控成形磨削凹面凸轮轴新工艺。给出了小砂轮半径的计算公式，通过计算凹面轮廓的最小曲率半径，对比判断是否需要切换砂轮。详细分析了大砂轮与小砂轮复合数控成形磨削凹面凸轮轴新工艺过程，并在CNC8325B全数控凸轮轴超高速复合磨床上进行了高速磨削加工实验，实验结果表明，该工艺方法可以实现凹面凸轮轴轮廓的磨削成形加工，满足了加工精度要求。

By analyzing the difficulties about the concave contour of camshaft in CNC grinding ,a new grinding process that the concave camshaft is machined by two grinding wheels of different diameters was proposed .A calculation formula about the small wheel radius is given ,and calculating the minimum radius of curvature of the concave contour can help us decide whether it need to switch the grinding wheel .Analyzes in detail the profile grinding process with large size and small size grinding wheels .Be-sides,some experiments are also carried out on the CNC 8325B ultra high speed camshaft grinder .The experimental results show that the concave contour grinding of camshaft can be achieved by this new process and meet the machining accuracy require -ments.
