1、ee基于IMAGEWARE少齿数齿轮逆向工程与制造ee（ee）指导教师:ee[摘要]少数齿轮的CAD模型常常需要由一个实体来构建。这个过程称为逆向工程，它是通过对齿轮使用三坐标扫描仪进行空间数字化来实现CAD造型。空间数字化产生齿轮的点云数据，这就是在surfacer中构建曲线的基本特征。在surfacer中对点云进行去除杂点，摆正，切片分层，最后拟合出曲线。然后将拟合出的曲线导入Pro/E/软件，使用Pro/E/软件中的曲线曲面建构命令做出三维实体，设计出其注塑模具。利用MASTERCAM软件对模具进行数控仿真加工，生成加工程序代码。该过程包括了逆向
2、工程、点云处理、曲线拟合、曲面构建、实体生成和模具设计与制造以及IMAGEWARE公司surfacer软件、PTC公司pro/E软件和CNCsoftwareNC公司的MASTERCAM软件的操作使用。本文介绍了少数齿轮的设计开发流程，利用先进设计与制造技术来快速实现少数齿轮生产。[关键词]：少数齿轮；逆向工程；点云；曲线拟合；曲面构建；实体建模；模具设计；仿真加工；CAD/CAMlocatedintheTomb,DongShenJiabang,deferthenextdayfocusedontheassassination.Linping,Zhejia
