为了解决非圆曲面零件的自适应磨削加工问题,在磨削力测量机理研究的基础上设计了一种基于模糊控制算法的自适应磨削机,采用力反馈模块和STM32控制器模块作为主控硬件,在Keil uVision 5环境下进行模糊控制程序的开发.样机磨削对比实验表明,在对非圆曲面零件如凸轮类零件进行打磨中,采用模糊控制能使磨削力保持稳定,利用三维表面形貌仪进一步实验分析表明,使用该自适应磨削机可有效的提高零件表面的加工经济精度,表面粗糙度较传统的打磨方法降低,是一种自动化磨削机可行有效的实现方法.%In order to solve the problem of adaptive grinding for non-circular curved surface parts,an adap-tive grinding machine based on fuzzy control algorithm is designed after the research on the measuring mech-anism of grinding force. The STM32 controller module and the grinding force feedback module are adopted as the main hardware,and the fuzzy control program is developed in the environment of Keil uVision 5. The prototype grinding contrast experiments show that the adaptive grinding machine can be effectively used to improve grinding precision parts of the surface and keep the grinding force steady in the grinding experiment on non-circular curved surface parts such as cam parts. The three dimensional surface topography analyzer is used to further analyze the results which shows the adaptive grinding machine can effectively improve the machining economic accuracy of the parts surface and the the surface roughness is lower than the traditional grinding method,and it is a feasible and effective method to realize the automatic grinding machine.
