摘　　要：以轿车差速器直齿圆锥齿轮为研究对象,借助UG的二次开发工具UG/OPEN中的API,UIStyler,MenuScript和集成开发环境Visual C++6.0,开发出基于UG的汽车差速器直齿圆锥齿轮CAD/CAM系统。该系统利用参数化建模技术实现了齿轮的三维参数化造型,提高了设计质量和设计效率;采用UGWAVE技术实现了部件间关联建模;使用数据库技术体现了加工参数数值的稳定性;同时使加工性能得到保证;运用UG内部调用DLL(动态链接库)功能实现和UG界面的无缝集成;最后的数控加工模块对齿轮凹模进行模拟加工并生成刀具加工的轨迹G代码。A specialized CAD/CAM system of bevel gear for car differential mechanism is developed by using the secondary development tools of UG/Open API,UG/Open UIStyler and UG/Open MenuScript,and integrated development environment Visual C++ 6.0.The system utilizes parameterized modeling technology to obtain a 3D gear model,and improve the design quality and design efficiency.The correlation modes between components are realized with UG WAVE technology.The use of database technique ensures the stability of values of parameters and the attribute during processing.The system realizes the integration of UG system by means of the function for the internal call DLL(Dynamic Link Library).At last the machining process of gear die is simulated in the numerical control module and the G code of the machining tool path is generated.
