摘　　要：面向高速铣削中锡铋合金异形曲面表面粗糙度工艺参量优选控制,研究了多变铣削参量与表面粗糙度的影响规律,基于田口稳健优化设计原理优化了铣削参量,并分析了铣削参量对切屑形貌的影响。建立了以主轴转速、铣削深度、进给速度、铣削行距为主要研究因素的正交实验方案,通过信噪比分析得到铣削行距是影响加工质量最重要的工艺参数,其次为铣削深度、主轴转速,而进给速度影响较小;综合稳健优化原理和铣削环境确定了铣削参数优选组合;并辨识了切屑形貌与表面加工质量关系。该研究方法对提高锡铋合金异形面加工表面完整性提供了依据。In order to improve the surface quality of Tin-Bismuth alloy shaped surface, the influence law of surface roughness under multi-turn milling environment was studied, and the chip morphology in the corresponding environment was observed. The orthogonal experimental scheme with spindle speed, milling depth, feed speed and milling line spacing as the main research factors is established. The milling distance is the most important process parameter affecting the processing quality of tin-bismuth alloy, and the feed rate is different. Surface machining quality has the least impact. The experimental results were optimized based on the robust design optimization principle, and the optimal milling process parameters were determined. In addition, it was found that the chip shape has a certain correlation with the surface quality. It is provides a method for improving the surface integrity of the Tin-Bismuth Alloy.
