Research on Fault Diagnosis iagnosis Based on BP BP-SOM Hybrid ybrid Algorithms lgorithms for NC machine

摘要

NC machines are more and more widely used in manufacturing industry. As the ke key equipments in the factory, NC machines should be closely monitored to avoid faults. Therefore, the research on multi multi-function diagnosis based on BP BP-SOM is discussed for NC machine in the paper paper. Taking the precision data as the basi basic data for diagnosis, t the research used BP and SOM algorithms he to build up diagnosis models. As a result, the research has accomplished the diagnosing process and acquires good simulation output, which resembles with the real fact.
