摘要: 
本研究為切削參數對車削球塞之加工效能之影響分析。本文所考慮主要的切削參數為進給率、切削深度、切削速度。而本文考慮之加工效能為表面粗糙度與體積移除率。

先根據切削理論分析各參數對加工效能之影響。再利用經驗參數建立實驗參數組合。經田口法實驗設計與驗證,據以瞭解各參數間的交互作用關係與各參數對加工效能之影響。

本實驗之變異數分析結果得知,在刀具幾何不變時,對於表面粗糙度之影響度,進給率影響最大,次高為切削深度,在固定進给率之下,切削速度的影響最小。增加切削深度,切削力會上升,會使表面粗糙度變差。以形成最佳表面粗糙度之進給率切削時,即使提高材料移除率而增加切削速度,仍可維持良好的表面粗糙度。另已磨耗刀具之切削也加入為考慮參數,得知刀具磨耗變大將使表面粗糙度變差。

This research is to analyze the effects of cutting parameters to cutting performance for ball valve shell turning. The cutting parameters are feed rate, depth of cut and cutting speed. The cutting performance is the measurements of surface roughness and material removal rate.

According to basic cutting principles, the influences of each parameter on cutting performance are analyzed. The arrangement of experimental parameters is then established using experienced parametric data. Through the design and verification of Taguchi method, the individual effects and interactive effects between parameters on machining performance are evaluated.

From the ANOVA Taguchi method for analyzing the results of the experiments, the effects of cutting parameters on machining performance show that feed rate has the most effects, depth of cut ranks next , and cutting speed has the least effect under a fixed feed rate. While increasing depth of cut, cutting force increases such that surface roughness worsens. At a feed rate with optimal surface roughness, although the cutting speed is increased to raise the material removal rate, the surface roughness can still remain in a good condition. Furthermore, tool wear is added as an influence parameter for cutting in this research, our experiment shows that an increase of tool wear worsens surface roughness.
