Design of Cutting Test Analysis System Based on Multi Parameter Information Fusion
[Purposes]In order to improve the accuracy and stability of workpiece machining quality,a cut-ting test system based on multi-parameter information fusion of cutting force and cutting temperature sig-nals was designed,so as to optimize cutting parameters and improve the overall machining efficiency.[Methods]Firstly,the empirical model of cutting force and cutting temperature was analyzed,and the three factors of cutting depth,cutting speed and feed rate are selected to study the degree of influence on cutting force and cutting temperature.Then,the sum of squares of deviation of variance analysis(SS)and the sum of mean squares of deviation(MS)were selected to analyze and evaluate the data of orthogonal test.Finally,the experimental analysis was carried out.[Findings]The analysis results show that the in-fluence degree of these three factors on cutting force and cutting temperature was from large to small,in order of back cutting quantity,feed quantity and cutting speed.[Conclusions]Therefore,in the actual machining process,the cutting parameters can be reasonably interposed according to the influence of these three cutting factors on the cutting force and cutting temperature,and the cutting efficiency can be improved.
