The power sensor was used to monitor machine processing power which was more practical and of no influence on the cutting process in comparison with conventional sensors such as force and AE.For the collected power signal,based on the analysis of signal features,a Re-processing Sparse Bayesian Learning(RP-SBL) with Non-dominated Sorting Genetic Algorithm Ⅱ(NSGA-Ⅱ)approach was proposed to achieve the tool wear prediction.First,the features re-processing was applied to eliminating impacts caused by power fluc...
