Fuzzy neural hybrid system for condition monitoring

In manufacturing processes, it is very important that the condition of the cutting tool, particularly the indications as to when it should be changed, can be monitored. Cutting tool condition monitoring is a very complex process and thus sensor fusion techniques and artificial intelligence signal processing algorithms are employed in this study. The multi-sensor signals reflect the tool condition comprehensively. A unique fuzzy neural hybrid pattern recognition algorithm has been developed. The weighted approaching degree can measure the difference of signal features accurately and the neurofuzzy network combines the transparent representation of fuzzy system with the learning ability of neural networks. The algorithm has strong modelling and noise suppression ability. These leads to successful tool wear classification under a range of machining conditions.
