| 中文摘要 | 螺絲與螺栓屬常見的螺紋緊固機械零 件,一般會作為機構連接鎖固使用,方便多 個組件的組合,與 接不同,鎖固機構的功 能易於調整、易於拆卸。而螺紋切削製造主要 有車削、銑削、攻絲、套絲、磨削、研磨、旋風切 削及高效率的專用機滾壓成形,至於特殊之螺紋元 件,則以車床加工即可,但對大型工件的大口徑螺 紋及管牙內螺紋加工則因為工件無法架上車床加 工,則必須仰賴 CNC 三軸聯動銑削進行螺紋加工 如再配合五軸加工刀軸朝向的靈活變化度,則取得 了良好的效果以克服大型工件的大口徑螺紋及管牙 內螺紋各總朝向加工的困難度,本研究計畫以客戶 接單的飛機引擎測試架工件進行,內含大口徑螺紋 M56 x 5.5 深度 130mm 盲孔,M48 x 5.0 深度110mm 盲孔內螺紋加工及美制NPT2-11.5 (inch)管牙內螺 紋加工為目標,開發測試海德漢控制器 (Heidenhain) 複循環 NC 程式(cycle 262) 內螺旋 銑牙加工及電腦輔助製造(CAM)對錐度 1:16 NPT 管牙內螺紋的銑牙刀螺紋加工 NC 程式。 |
| 英文摘要 | Screws and bolts are common threaded fastening mechanical parts, which are generally used as mechanism connection locking, which is convenient for the combination of multiple components. The thread cutting manufacturing mainly includes turning, milling, tapping, threading, grinding, polishing, whirlwind cutting and high-efficiency special machine rolling forming. As for the special thread components, it can be processed by lathes, but for the large-diameter threads and pipe teeth internal thread processing of large work pieces, it must rely on CNC three-axis linkage milling for thread processing. In order to overcome the difficulty of machining the large diameter thread and the internal thread of the pipe tooth in each direction of the large work piece, this research plan is carried out on the work piece of the aircraft engine test frame, including the large diameter thread M56 x 5.5 depth 130mm blind hole, M48 x 5.0 depth 110mm blind hole internal threading and the American NPT2-11.5(inch) pipe tooth internal threading processing as the goal. Develop and test the internal thread milling with Heidenhain controller's Cycle 262 and Computer-Aided Manufacturing (CAM) NC program for thread milling for internal threads with a taper of 1:16 of NPT pipe tooth. |
