回转体零件CAD／CAM集成系统采用特征造型技术建立统一的产品信息模型，实现CAD／CAPP／CAM的高度集成。CAD模块用特征造型方法完成零件的设计，建立零件的特征模型。CAPP模块根据零件的特征模型自动生成零件毛坯，制订工艺路线。CAM模块完成加工路线的规划、刀夹具的选择、切削参数的确定。API模块生成NC代码。仿真模块模拟毛坯的加工过程、检测干涉和NC代码的正确性；NC编辑模块完成对NC代码的编辑和修改。 Rotary body parts CAD / CAM integrated system using feature modeling technology to establish a unified product information model to achieve a high degree of integration of CAD / CAPP / CAM. CAD module uses the method of feature modeling to complete the design of the part and build the feature model of the part. The CAPP module automatically generates part blanks based on the feature model of the part and formulates the routing. CAM module to complete the processing route planning, tool holder selection, cutting parameters to determine. The API module generates the NC code. The simulation module simulates the machining process of the blank to detect the interference and the correctness of the NC code. The NC editing module completes the editing and modification of the NC code.
