Fault diagnosis of numerical controlled machine based on comprehensive fuzzy method

摘要

To make up the shortcoming of numerical controlled machine fault diagnosis, a comprehensive fuzzy decision-making method is proposed in this paper. The new method combines fault phenomenon with fault reason. Based on the theory of fuzzy mathematics, the fuzzy relationship model between fault phenomenon and reason is established. And the comprehensive fuzzy diagnosis is realized with T-S model. Based on the experience of multi-experts, the proposed method improves the reliability of diagnosis, and provides convenient for practical repair of numerical controlled machine.
