在這個講求效率及準確度的時代，電腦輔助製造(CAM)已經漸漸取代傳統手寫NC程式，由軟體計算產生加工路徑，直接在電腦上預先模擬，能加工出較複雜或精度要求較高的零件。當操作CAM時會因為編製人員的主觀想法及本身的加工經驗，使用到不同的加工策略與細部的設定，導致公司難以規範與管理，此外，由於操作步驟過於繁雜，且受限於編製人員的經驗，而降低了編製加工路徑的效率。因此，精簡化操作步驟與重複性的流程、降低操作的門檻、有效提升編製加工路徑的效率是本研究要探討的重要課題。
本研究是根據車床的加工經驗與規則，利用德國Siemens公司開發的NX軟體進行二次開發，與Visual Studio C#配置二次開發環境，建構專用於NX二次開發的專案，藉由NX提供的API程式庫，將NXOpen組成的功能程式導入Visual Studio C#編寫，開發專用於車削CAM的整合系統，整合軟體內常用到的車削加工法，包括粗加工端面、粗加工外徑與內徑、精加工外徑與內徑、內徑切槽工法。於NX功能表建立自定義功能選單，作為執行本系統的入口並取代原先NX車削CAM各項工法的對話框介面，採用多頁面的設計並精簡化對話框內容，將各工法的對話框內容整合在同一個介面中操作，指定切削區域與輸入切削參數，確定後同時產生各工法的加工路徑，接著利用建立的車床後處理將NX產生的路徑資料匯出NC程式碼於Vericut模擬切削，最後實際上機切削零件驗證本系統生成的加工路徑是可行的且具有合理性。本論文所提出的系統應用參數化輸入及規格化加工策略的設計，使得編製車削CAM的過程更精簡化、縮短了編製的時間、減少人為設定上的疏失、降低操作的門檻。

Computer-aided manufacturing (CAM) has replaced the handwritten NC code gradually. The CAM software calculates to produce tool paths, and directly simulates on the computer. This software helps to manufacture complicated yet precise components. When an engineer operates the CAM system depending on his experience and subjective ideas to decide the cutting strategy, this situation could reflect some difficulties in standardization and management of manufacturing companies. In addition, manually designed operation steps maybe too complicated, leads to reduce the efficiency of tool path planning. Therefore, this study not only researched on how to simplify the operation steps and procedures but also reduced the operational threshold.
This thesis uses Siemens NX with Visual Studio C# to configure the secondary development environment. This study also adopts the API library provided by Siemens NX to import NXOpen function language into Visual Studio C# for program edition. For the development of a CAM-integrated turning system, this includes some common machine operations, such as the rough turning of the object’s surface, outer- and inner diameter, the finish turning of outer- and inner diameter, and the grooving of the inner diameter of an object. This integrated system is triggered by a custom menu in NX. The dialog interface of the system is designed to be multi-paged with streamlined content. All operations and parameter settings are integrated in the main interface. The path data generated by NX are exported into NC code with a novel lathe post-processor, which established in this study. Then, this NC code is imported into Vericut software for cutting simulation. Ultimately, the parts are practically cut using a CNC lathe machine. The actual cutting results verify that the tool paths generated in this system is feasible and reasonable. This study simplified the CAM turning process by parameterize the input of operations and standardize the processing strategy, thus increased the efficiency of tool path planning, and reduced human errors and operational thresholds.
