摘　　要：快速原型技术和逆向工程相结合可以提高柴油机进排气道的模具和铸件的精度,缩短模具开发周期。利用数字化测量设备获取实体点云数据,在CATIA环境下对这些点云数据进行拟合,构建一个完整的CAD模型,然后采用Pro/E软件设计进排气道的模具,在MasterCAM环境下生成其模具数控加工程序。The processing integrated reverse engineering and rapid prototyping can improve the precision of toolings and castings of inlet and exhaust ports of desel engines, and shorten toolings development duration. The digital measure equipment can be used to acquire the discrete date also called point cloud. The surface is fitted from these obtained data in the condition of CATIA software. In this way, gain the solid model that rapid pro- totyping requires. And then mould are designed by adopting Pro/E software. At last, NC machining of the toolings of manufacture was conducted by adopting MasterCAM system.
