主 题:Fault diagnosis tool condition monitoring REPTree decision tree statistical feature extraction
摘 要:Tool wear is inevitable in daily machining process since metal cutting process involves the chip rubbing the tool surface after it has been cut by the tool *** wear dominantly influences the deterioration of surface finish,geometric and dimensional tolerances of the ***,for complete utilization of cutting tools and reduction of machine downtime during the machining process,it becomes necessary to understand the develop-ment of tool wear and predict its status before *** this study,tool condition monitoring system was used to monitor the behavior of a single point cutting tool to predict flank wear.A uniaxial accelerometer was attached to a single point cutting tool under *** accelerometer acquires vibrational signals during turning operation on a lathe *** acquired signals were then used to extract statistical features such as standard error,variance,skewness,*** substantial features were recognized to reduce the utilization of computing *** were used to classify the signals as good and three different measures of flank wear by a decision tree *** domain features were also extracted and shown to be less effective in classification in comparison to statistical ***(Reduced Error Pruning Tree)algorithm was used in this *** decision tree algorithm achieved a maximum classification accuracy of 72.77%for all signals *** spindle speed and feed rate are considered as the variables the accuracy is about 86.25%.When spindle speed is the only variable parameter the accuracy is about 82.71%.When depth of cut,feed rate and speed of the spindle are considered as variable parameters,the accuracy of the decision tree is around 93.51%.This study demonstrates the performance of REPTree classifier in tool condition *** can be utilized for tool wear identification and thus improve surface finish,dimensional accuracy of the work piece and reduce machine *** add
