摘要
为获得理想的高温合金GH4169铣削力、表面残余应力以及表面粗糙度,提出了面向多目标的铣削工艺参数优选区间划分方法,设计了四因素四水平铣削正交试验;根据试验结果标准差计算了工艺参数对各优化目标影响的权重系数,并将多优化目标变换为综合优化目标;通过趋势图分析了各个优化目标随工艺参数增大的变化机理及趋势;按照所提方法确定了工艺参数优选区间,并通过实验进一步验证了优选区间的可靠性。
In order to obtain ideal milling force,surface residual stress and surface roughness of superalloy GH4169,a multi-objective optimal interval division method for milling process parameters was proposed,and four-factor four-level milling orthogonal test was designed;according to the standard deviation of the test results,the influence weight coefficients of process parameters on the optimization objectives were calculated,and multiple optimization objectives were transformed into a comprehensive optimization objective;the change mechanisms and trends of the optimization objectives with the increasing values of process parameters were analyzed via the tendency chart;the optimal interval of process parameters was determined through the proposed method,and its reliability was further verified through an experiment.
