摘　　要：以数控凸轮磨床的磨削过程为研究对象,建立了凸轮磨削过程的磨削力数学模型,研究了磨削力的间接检测和控制方法,并在此基础上提出一种基于模糊策略的适应控制方法对凸轮磨削过程的磨削力给予控制,采用MATALAB进行了控制器的设计和磨削加工的仿真验证,结果表明该方法能有效地解决凸轮磨削过程中的磨削力的波动问题,控制器具有良好的动态特性,实现了磨削过程中的最优金属切除率的目的,提高了凸轮磨削的表面质量。Taking the grinding process of numerical control cam grinding machine as research subject,the grinding force mathematical model is built,the indirect testing and control measures are researched and an adaptive control method based on fuzzy strategy is proposed and applied to the grinding force control of the cam grinding process.At last,the controller is designed and the grinding simulation is performed with MATLAB,which proved that the system can solve the fluctuation of grinding force during the process of cam grinding and the controller is equipped with good dynamic characteristic.The results indicate that the method can realize the purpose of optimal metal removal rate and enhance the grinding quality of cams.
