基于Pro/Toolkit的实体模型尺寸信息的提取

Dimension Information Extracting of Solid Model based on Pro/Toolkit

针对零件几何信息的识别与提取 ,给出了基于Pro/Toolkit的实体模型尺寸信息的提取方法。在Pro/ENGINEER系统中创建了实体模型尺寸信息的“修改与提取”菜单 ,利用此菜单可以生成模型尺寸信息的数据文件 ,为实现CMM(三坐标测量机 )的自动检测提供了尺寸信息的来源 ,同时通过此菜单可以准确、快捷地对模型的尺寸数据进行实时动态地修改。通过实例验证了所开发的实体模型尺寸信息提取方法的正确性 ,对其它后续开发工作具有很好的指导意义。

The extracting method of dimension information of solid model based on the Pro/Toolkit is presented for the identifying and extracting of geometry information of parts. The modification and extraction menu of dimension information of solid model is established in the Pro/ENGINEER system, through which the model dimension information datum document can be created, which supplies the resource of dimension information for the inspecting automatization of CMM(coordinate measuring machine). At the same time, the model dimension datum can be modified correctly and rapidly in real time. The given example validated the developed extracting method of dimension information of solid model. It is very instructive for the future developing works.
