中文摘要 | 以高速加工機具執行端銑切削已廣泛應用於精密機械產業各種產品的生產加工,解決生產高精度、低成本及外形變化複雜模具之加工問題,為維持模具產業競爭力的關鍵技術之一。然而加工產品的可靠度取決於各種工程參數的設定,所以高速加工過程中加工條件及環境的設定與掌控,自然成為精密機械加工的重要課題之一。面對全球市場的國際化競爭壓力,如何制定提高產能、降低成本、掌控產品品質及減少不良率等可行策略,一直是產業維持成長與競爭力的努力目標。 本文依據加工表面狀況及尺寸精度於圓弧銑削加工時,使用田口分析法之品質工程規劃法找出一組昀佳化加工條件。實驗使用機械設備為楊鐵 MV-3A CNC銑床,粗銑端銑刀24,精銑端銑刀10,在 6061鋁合金材料上做 R20的1 4圓弧精銑削。本研究利用直交表先規劃相關實驗項目之數據,經由信號雜音比 S/N計算與變異數分析等過程來進行田囗分析,以獲得不同加工因子對目標品質的影響,進而求得 MV-3A於銑削圓弧時昀佳化加工參數。實驗結果證實利用昀佳化加工參數可有效提升加工品質 20%~50%,降低成本,減少加工損失並獲得昀佳表面狀況與尺寸精度。 |
英文摘要 | End milling with high speed machining is widely used to the production of different products of precision machinery industry. In order to maintain the mould industry's competitiveness, a process program with high accuracy, low cost and the shortening of finishing time is an important key technology to the manufacturing of the complicated mould. The reliability of the processing products depends on many parameters and engineering decisions. Therefore, the cutting condition and environment control in the high-speed machining naturally become one of the precision machinery important subjects. The present study aims to establish optimal cutting conditions of three-axis machine tools in end milling using Taguchi method. In the experiment, four parameters of cutting conditions are considered. The objects of quality include surface toughness, dimensional accuracy, roundness and cutting time. Various set of objects can be acquired in different cutting conditions. Therefore, the optimal cutting conditions can be obtained by using the analysis of variance procedure. The benefits of this experiment were verified. |
