中文摘要 | 針對不規則或複雜幾何曲面設計的不易及減少加工的因雞,發展了整 合電腦輔助設計及製造方法,並以加工參數選擇為基礎的銑削加工交談式專家系 統來增加效率。文中,在電腦輔助設計部份使用雙三次B樣條曲面法則及繪田 支援軟體產生加工元件之幾何形狀。其次,將基本加工參數輸入專家系統即可按 加工元件之幾何形狀,獲得適切的加工參數及刀具種頗,維之,在終端機按不同 參數方向進行下列三權加工模擬:(1)沿u軸單向加工,(2)沿v軸單向加工,(3)研u 及v軸迴旋加工,以找出適切的加工方式,並將其資料轉成NC加工碼進行加工。 最後,以鞍面曲面為例,由設計至製造的全程工作來驗證此系統之適用性。 |
英文摘要 | To improve the geometric design on irregular or complex surfaces and to reduce the difficulty in machining, an interactive expert system, which is based on the choosing of machiningparameters, is integrated with CAD/CAM system for more efficient milling machining. Theprocess of this integrating is as follows: First, use the bicubic B-spline surface modeling algorithm with the graphic supportingsoftware (GSS) in the CAD system to generate desired geometric models for machining parts.Second, input all the fundamental machining factors into the expert system. According to thedesigned geometric model, the proper machining parameters and suitable tool can be obtained.Third, test the machining tool path in turn in three ways:(l) cut along the staircase of the uaxis (2) cut along the staircase of the v-axis (3) cut rotationally along the u and v-axes. Afterfinding the best tool path through simulation, this information can be transferred to the NCcode for machining. Here we take a saddle surface for example to demonstrate the feasibilityof this system. |
