摘要
为提高多头螺杆转子的加工质量,文章探究了外包络铣削工艺参数对表面粗糙度和硬度的影响,并对工艺参数进行优化.以主轴转速、间歇进给量及加工倍率作为因素进行正交试验,试验结果表明:加工倍率是影响表面粗糙度值最主要的因素,间歇进给量是影响显微硬度值最主要的因素.采用多目标优化算法对工艺参数进行优化,得到最优工艺参数组合如下:主轴转速为 191 r/min,间歇进给量为 3.1 mm,加工倍率为 15%.用该组参数加工可使表面粗糙度值降低 17.15%,显微硬度值提高 7.60%.文章提出的方法可为工艺参数的优化提供参考.
Abstract
In order to improve the machining quality of multi-head screw rotors,this paper explores the influence of outer envelope milling parameters on surface roughness and hardness was investigated,and the parameters were optimized.Orthogonal tests were carried out with spindle speed,intermittent feed rate and machining rate as factors.The results show that machining rate is the most important factor affecting surface roughness value,and intermittent feed is the most important factor affecting microhardness value.The multi-objective optimization algorithm was used to optimize the process parameters,and the optimal combination of process parameters was obtained as follows:the spindle speed was 191 r/min,the intermittent feed rate was 3.1 mm,and the machining rate was 15%.The surface roughness value can be reduced by 17.15%and the microhardness value can be increased by 7.60%.The method presented in this paper can provide reference for the optimization of process parameters.
