The reliability analysis of a thin-edge blade wear in the glass fiber cutting process

This study shows that the reliability analysis of a thin-edge blade plays an important role in cutting glass fiber and explores the main effect of three cutting factors: the cutting speed, the cutting load, and the cutting volume. The effect of each cutting factor on the thin-edge blade wear, as determined by long glass fiber weight, and exceeding a value of 1%, as specified in the customerʹs requirements, was investigated. According to the experimental results, the thin-edge blade wear distribution approximated to a Weibull distribution, and the cumulative probability could be determined after nine iterations. This study also finds that there is a large positive correlation among the various thin-edge blade-wear values at different cutting speeds. However, the correlation is negative for the various thin-edge blade-wear values when cutting at load, and when cutting at different cutting volumes. It was observed also that the optimum cutting speed with minimum thin-edge blade wear is 1.9 m/s. The successful deployment of this study will be a significant factor in improving the cutting process and cutting quality.
