摘　　要：为使弧面凸轮机构在设计过程中具有修改柔性,设计周期短和高效等优点,利用NX Open C经典应用编程接口与Microsoft visual studio(VS)实现连接,用户可通过NX Open应用程序开发菜单、工具条、对话框等工具实现交互设计,对话框通过调用回调函数激活相应控件,应用程序(回调函数)通过相应的编程语言与NX Open API进行编码。基于NX软件二次开发功能,结合VS开发一款适用于弧面分度凸轮机构快速建模的参数化设计系统,可实现可视化交互设计。结果表明,参数化设计后的系统极大地缩短了设计时间和减少了繁琐的重复劳动。In order to make the globoidal CAM mechanism in the design process has the modification flexibility,the design cycle being short and efficient and so on,this paper uses NX Open C classic application programming interfaces(apis)and Microsoft visual studio(VS)to realize the connection,so that the user can employ the NX Open application development menus,toolbar,dialog boxes,such as tools to implement and interaction design,dialog box by calling the callback function to activate the corresponding controls,application(callback function)through the appropriate programming language and NX code Open API.Based on the secondary development function of NX computer software,a parameterization system suitable for rapid modeling of globoidal indexing CAM mechanism was developed in combination with VS to realize visual interaction design and global optimization.The results show that the system with parameterization design greatly shortens the design time and reduces the tedious repetitive work.
