摘要


本研究以灰關聯分析探討高速端銑SKD61模具鋼精加工製程時以表面粗糙度及表面波紋為性能指標之切削參數最適選擇。首先以直交表規劃實驗。接著,結合灰關聯分析法將多重品質特性值客觀轉換為單一性能指標,即灰關聯度。將分析所得灰關聯度值經由變異數分析與因子分析,找出一組滿足多重品質特性的切削參數最佳解。驗證結果顯示,本研究所得到的切削參數最佳水準組合,確實能夠同時有效改善加工件之表面粗糙度與表面波紋。

並列摘要


This study aims at producing an optimal cutting-parameter design for a finishing process for high-speed end milling using the grey relational analysis. The workpiece materials is SKD61 tool steel.The major performance indices chosen to evaluate the workpiece quality are surface roughness and surface waviness. The Taguchi method was used to produce parameter design for all experimental trials and the multiple performance characteristics(MPC)were evaluated using S/N ratio. The grey relational analysis was then used to convert the MPC into a single performance index. The Optimum design can be found by the analysis of variance and control factors response table on the single performance index. The confirmation results show that the surface roughness and surface waviness were significantly improved by the optimum design predicted by the grey relational analysis.
