中文摘要 | 本文使用反應曲面法之有效率流程於V 型彎曲過程中進行實驗設計與性能分析。 並針對其設計參數如衝頭半徑、模具寬度、模具彎角半徑與試件厚度等對回彈角度與 彎曲後厚度變化等彎曲特徵之影響加以探討。反應曲面法中標準設計法稱為中央組合 轉動設計法為本文實驗設計所採取用。經由變異數分析與實驗驗證後,本文所提出二 階模式非常適合於解釋與分析其設計參數對彎曲特徵之影響,而其獲得預測值非常接 近實驗值,且在95%信心指數範圍內。其設計參數之最佳值設定經由反應曲面法之二 階模式與連續近似最佳化法來獲得。其結果顯示為其模具寬度、模具彎角半徑與試件 厚度等參數於彎曲特徵評估上是顯著性因子,也是在提升其品質上重要的參數。經由 實驗證實本文所提出最佳設計參數之設定於V型彎曲過程中對於其彎曲特徵評估有很 大的改善。 |
英文摘要 | In this study, an effective procedure of response surface methodology (RSM) was utilized for experimental design and performance analysis of the V-die bending process. The punch radius, die width, die corner radius and blank thickness were selected as effective processing parameters to investigate the influences on the performance of spring-back angle and thickness variation in the bending process. A standard RSM design called the centered composite rotatable design (CCRD) was applied in this experimental plan. Based on the analysis of variance and verification experiments, the quadratic models proposed in this paper were adequate to explain and analysis the effects of processing parameters, and can be utilized to predict the experimental value within the 95% accurate interval. The optimal conditions were also determined using the proposed quadratic model and the sequential approximation optimization method (SAO). Results show that the significant factors on the bending performance evaluations are the die corner radius, die width and blank thickness, which are noticeable variable factors as the resources of increasing quality. The experimental results using the optimal setting were easily clarified that the effective procedure proposed in this study greatly improved the desired target of performance analysis in the V-die bending process. |
