摘要
为研究新型高韧性奥氏体高锰钢材料的切削加工性能,使用涂层硬质合金钻头,在正交统计试验设计方法指导下,进行了切削抗力特征规律试验研究,获得了钻削抗力(扭矩和轴向力)与切削用量之间的特征规律,得到了高置信度的回归经验公式。研究得出如下结论:进给速度对切削抗力的影响为对数线性正增关系;主轴转速对切削抗力的影响呈对数非线性关系;在满足切削抗力约束条件下,实现切削效率的最大化的切削用量组合,可以通过统计试验设计指导下的切削试验予以确定。
Aiming to study the maehininability of a new austenite manganese steel, by using of uniform design, the dependence of drilling resistances （torque and axis force） on cutting parameters were withdrawn. It is concluded that the relationship between cutting resistances and spindle speed shows a nonlinear trend;feed rate has a significant influence on cutting resistances ;the uniform experimental design method could be used to determine the optimum drilling parameters.
