Adaptive Control of CNC Machining Parameters Based on Fuzzy Control Theory

针对数控加工参数对整个加工过程的重要性,阐述了一种基于模糊控制理论的数控加工参数自适应控制方法。根据建立的控制模型和模糊控制原理,编写C++源程序,并模拟实验数据进行验证程序的可行性,最后通过VC++可视化软件,将源程序嵌入到现有的数控系统中,实现了加工过程自适应控制的动态显示。结果表明了自适应控制模型的有效性,使数控机床在加工过程中保持良好的稳定性。

For the importance of NC machining parameters on the machining process, the adaptive control method of NC machining parameters is elaborated based on fuzzy control theory. According to the established control model and the fuzzy control principle, this paper compiled C++ source procedure, and simulated the experimental data to verify the feasibility of procedures, and finally, embedded the procedures into the existing numerical control system by the VC++ visual software, achieved the dynamic display of adaptive control processing. The results showed the effectiveness of the adaptive control model and made NC machine maintain the good stability in the whole machining process.
