技術說明

關鍵詞：龍門工具機、滑動導軌、鏟花、介面元素，耐磨襯墊 本計畫旨在探討貼附耐磨襯墊（Turcite B）滑軌之摩擦特性以及採用此類滑動導軌之工作 台之動靜態特性。在實務應用上，耐磨襯墊黏貼在滑動件或鞍座之滑動面後，須經鏟花處 理產生適當表面承班形貌，以提供滑動介面適當摩擦性質與潤滑效果。而鏟花加工參數則 是影響表面承班形貌之重要因素。為避免人工操作經驗或技巧之不足，影響接觸面之品質 與幾何精度，因此有必要藉助實驗量測與理論分析，以系統化方式來評估或建立耐磨襯墊 表面承班形貌、潤滑條件與滑動介面摩擦性質之間的相關性，提供往後滑軌鏟花施工的依 據。為能將上述結果實務性地應用在重型CNC龍門工具機，在具體化製造生產前，有必要針 對此種進給裝置之整體結構進行相關力學分析與實驗驗證。 因此，本計畫規劃分析項目包括(1)工作台導引裝置整體結構靜態剛性與動態特性分析（自 然振動頻率與振動模態）藉以評估工作台滑動介面鏟花之力學效應。(2)結構模態實驗，針 對整體結構進行振動分析，以瞭解結構自然振動頻率與振動模態。(3)工作台定位精度測 試，使用雷射干涉儀來量測前項實驗機台之定位精度。本計畫之執行可讓合作廠商突破傳 統技術對於人力經驗法則過於仰賴之知識障礙，進而在工具機相關領域具主導地位與國際 競爭力。 Keyword: Machine Tool, Slide guideway, Scarping, Interface element, Turcite B The purpose of this project is to investigate the friction characteristic of antifriction liner Turcite B and the mechanical performance of the guideway with sliding bearing. In practice of machine tool, the anti-wear liner bearing should be scrapped properly by hand operation after coated on the guideway to form a uniform surface bearing spots so that better contact geometry and lubrication condition can be kept for high precision positioning in machining. However, the less experience in scraping may result in poor surface roughness and hence positioning precision. To prevent such deficiencies for future application, the evaluation of effect of the scraping operation on the performance of the sliding guideway is therefore important and perquisites before practical application on the machine tool of heavy duty type. For this, a series of the friction tests will be performed on the sliders with different anti-friction bearings to evaluate the friction coefficients under different lubrications and loadings. After that a prototype of a sliding guideway with specified scraping pattern made on the sliding surface will be constructed for evaluating the dynamic characteristics and precision in positioning. The finite element method will be employed to analysis the static stiffness and dynamic characteristic of the machine structure under various operating conditions. Some conclusions will finally be drawn from the evaluation on the experimental results and numerical prediction on the structure design of the new system. It is believed that the proposed feed system can help the manufacturer to surmount the defects in machining of a traditional machine and enable them to develop the machine tool structure with excellent mechanical performance.
