高温合金GH3039铣削力实验研究

Experimental study on superalloy GH3039 milling force

由于高温合金材料GH3039的切削加工性差,选取背吃刀量、铣削速度、每齿进给量等参数,研究其对高温合金数控铣削力的影响。利用线性回归方法建立了铣削力经验公式,并通过铣削实验得到了切削参数与铣削力的变化曲线。实证表明切削参数的选择在GH3039加工过程中的重要性。

Aimed at improving the poor machining of superalloy GH3039,this paper identifies the effect of the axial depth,cutting speed and feed per tooth on the superalloy GH3039 milling force.The milling force experience formula is established by means of regression analysis.The experiment gives the curve of cutting parameters and milling force.The demonstration shows that the selection of cutting parameters is important in machining this kind of superalloy.
