Abstract
Due to discontinuous cutting of the milling cutters operating at high rotational speed,the milling tools wear quickly with difficult monitoring,which seriously affect the machining precision and product quality.In order to solve the on-line prediction problems of high speed milling tool wear,a deep learning-based method for predicting tool wear state in high speed milling is proposed in this paper.Firstly,a wavelet based method was used to extract the energy distribution of cutting force at different frequency bands as the initial feature vectors;Secondly,an unsupervised learning method was employed to learn the features of the sparse auto-encoder network,and the single layer networks were stacked to construct the deep neural network;Finally,the whole deep learning network was fine-tuned by a supervised learning method,and the prediction model of tool wear state was established.The experimental results show that the prediction accuracy of the proposed method is 93.038%.关键词
