隨著機械與自動化產業發展,工具機是在其中佔據著舉足輕重的角色,而要做到高速、高精度則是非常艱鉅的挑戰。組成一台精密工具機則須包含許多部份,如前段機台的設計、電控配置、組裝方法及後端精度調校都會影響到整體的精密性,而機械設計則是其中的骨幹,如果設計不良時則需設變而造成成本的浪費,而電控配置會因機台的設計變更而有所變化,所以在設計初期就需要考慮到結構剛性及電控配置等。 現今業界設計的方式大多仍以經驗作為判斷而無一設計準則,沒有固定的流程及方法,常常會使新手無所適從,從而犯下錯誤,而經驗的傳承又不是一時能完成,這種現象造成現今機械設計人員的斷層。本論文旨在建立一完整設計流程並輔以精度設計理論、有限元素分析及機電整合等相關方法,並以CNC車床為藍本,使用3D CAD軟體建立實體模型,佐以精度設計理論進行工程圖的標註達到精密的配合,同時以有限元素分析法分析結構剛性及模態分析,判別結構強度是否足夠,再搭配電控系統將機械與電控整合完成一台高精度之數控工具機。 最後將整個設計過程整合為一CNC工具機設計之標準作業流程,讓初跨入機械領域的新手能依據此研究流程,迅速進入工具機開發的領域,以期可讓初期設計之學習過程縮短並將出錯率降至最低。
The paper aims to establish a complete set of Machine Tools's research process combined with precision design, finite element analysis,mechanical and electrical integration and other related theories, In this research using SolidWorks modeled the solid model of CNC lathe first, then using the finite element method and ANSYS to analyze structure of lathe and stiffness, to determine the deficiencies ,structural rigidity and resonance point , of strength not enough , returning the solid model to modify it until the the design requirements is given, finish the simlation ,the solid model will used the design process and designed by the precision design.The method of precision design are in accordance with the theory and engineering specifications, mark the compliant of the project view, and finally using the control systems, planning processes ,ladder diagram of PLC and sequential circuit with automatic tool change of control, so the mechanical and electrical control integrated into a complete machine tool that can actuated by system. Due to the mechanical design of the current approach still needs a lot of experience as a foundation, which will make a loss for beginners, thereby committing an error, the entire study will be integrated into a design process in this article, let the novice of mechanical design can design the machine correctly and finish the research in no more experience situation. Finally if design in accordance with the design process can minimize the error rate , it also can be considered early in the design to structural rigidity and electric control configuration.
