考虑交互作用的A100钢高速铣削参数区间优选

Preferred Parameter Intervals for High-Speed Milling of A100 Steel Considering Interactions

为获得理想的高速铣削A100钢的铣削力和铣削温度,提出了一种考虑交互作用的铣削工艺参数取值区间的优选方法。以铣削力和铣削温度为响应变量并作为优化目标,设计了四因素四水平的正交仿真试验,得到了各工艺参数对响应变量的影响规律。利用熵权法得到了各响应变量的权重系数,结合灰色关联度分析理论将多个优化目标转化为一个综合优化目标。通过综合优化目标极差分析的主效应图得到了A100钢高速铣削工艺参数的优选区间,并利用枚举法得到了优化目标值的变化范围,经过与正交表中的响应值进行对比,结果表明所得优化目标的最大值均小于正交试验结果的平均值,满足优化预期。

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 obtained 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 comparing with the response value in the orthogonal table,the results show that the maximum value of the obtained optimization objective is smaller than the average value of the orthogonal test results,which meets the optimization expectations.
