A new method of intelligent identification of grinding burn and wheel wear in grinding process based on Rough Set Theory is studied in this paper. The grinding chips flow thermal signal by an infrared detector is used as the original signal source for analysis, and Rough Set Theory is applied to acquire rules and finally to realize intelligent identification in grinding process. The experimental results show that the new method is feasible. The new method using Rough Set Theory can be applied to the production pattern of large variety and small batch.
