摘要

隨著電腦運算能力提升，CAM（Computer-aided manufacturing）系統在CNC工具機加工技術佔有的地位日漸重要，而CAM系統的附加功能所帶來之便利性，也是加工人員選用該系統的重要考量因素。本文將針對工序解析對話式CAM系統提出一套基於車削加工特徵辨識的擴展功能，在取得車削工件的圖檔後，解析其輪廓特徵並轉換成符合車削加工邏輯的工序規劃，最後匯入CAM系統中進行切削模擬與生成加工NC碼。透過本擴展功能得以大幅減少NC碼建置的時間、降低操作人員的專業背景門檻，顯著提升整體車削加工之產業效能。

As the computing power continuous to grow, the CAM (Computer-Aided Manufacturing) system plays an increasingly important role in CNC processing technology. The convenience brought by CAM system's additional functions is also an important consideration for users in choosing CAM software. This article will introduce a set of extended functions based on the feature recognition in the domestic developed turning process analysis dialog type CAM system. After obtaining the drawing of turning workpiece, its contour features will be analyzed and converted into a process plan that conforms to the turning processing logic, and finally imported into the CAM Cutting simulation software and generated NC codes. Through theses extended functions, the time required for NC code construction can be greatly reduced. As such, the threshold for the operator's professional background requirement will be lowered, and the industrial efficiency of the overall turning processing will be significantly improved.
