摘要

提出了一种基于粗糙集模糊控制的微孔钻削在线监测的方法。克服了当模糊系统输入维数高时，系统模糊规则过多，计算过于复杂的缺点。在MATLAB环境下，应用构造好的模糊系统对主轴电机三相电流信号进行实时数据处理，获取隐含微细钻头磨损状态的信息值，对微孔钻削过程进行在线监测实验，结果表明，适当选择监测阈值，可以有效避免微细钻头的折断。

Abstract

For online monitoring micro-size drilling

a rough set-based fuzzy control method was developed. The method gets rid of the disadvantages of over many fuzzy rule numbers and complicated calculations toward high-dimensional input fuzzy system. On the MATLAB platform

spindle motor’s 3-phase current signal data were on-line produced. Then connotative wear state information of micro-size drill was obtained and on-line monitoring to micro-size drilling process was performed. Results show that when monitoring threshold value is properly selected

the breakage of micro-size drill will be effectively avoided.
