碩士 === 國立虎尾科技大學 === 機械與電腦輔助工程系碩士班 === 107 === 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.
