| Abstract: |
| Objective To study and analyze the surface roughness characteristics of sn-bi alloy to improve its surface pro-cessing quality. Methods The orthogonal test method was adopted, and the minimum surface roughness was used as the test index. The precision milling test was carried out with spindle speed, milling depth, feed rate and milling width as influencing factors. Results The ANOVA analysis confirmed that the feed rate was the most important factor in the roughness of tin-bismuth alloy milling. Based on the optimization of Taguchi method, the optimal combination of tin-bismuth alloy processing technology was obtained. Conclusion The Taguchi method is effective in optimizing the milling process of tin-bismuth alloy, which reduces the surface roughness and improves the surface quality of the work-piece. |
