Preferred Parameter Intervals for High-Speed Milling of A100 Steel Considering Interactions
In order to obtain the ideal milling force and milling temperature for high-speed milling of A100 steel,a method of optimizing the value interval of milling process parameters considering the interaction is proposed.Taking the milling force and milling temperature as the response variables and as the optimization objectives,a four-factor,four-level orthogonal simulation test was designed to obtain the influence of each process parameter on the response variables.The weight coefficients of each response variable were ob-tained by using the entropy weight method,and multiple optimization objectives were transformed into a comprehensive optimization objective by combining the theory of gray correlation analysis.The preferred interval of the process parameters for high-speed milling of A100 steel was obtained through the main effect diagram of the extreme difference analysis of the comprehensive optimization objective,and the variation range of the optimization objective value was obtained by using the enumeration method,and after compa-ring with the response value in the orthogonal table,the results show that the maximum value of the ob-tained optimization objective is smaller than the average value of the orthogonal test results,which meets the optimization expectations.
