摘　　要：金属模铸造研发过程中,在只有铸件实物情况下,铸件尺寸特征的精确获取是制定工艺方案和模具设计基本要求。本文用三维扫描仪对金属模铸件进行三维扫描获取了铸件点云,用计算机辅助测量软件对铸件和零件数模进行了三维比较分析。获取了铸件三维尺寸偏差、壁厚分布、加工余量、拔模斜度等重要信息。为金属模铸造工艺和模具设计提供了重要参考数据。In the R ＆ D process of metal mould casting, in the case of only having a physical casting, to exactly obtain the characteristics of casting size is a basic requirement in developing technology programs and designing casting mould using three-dimensional scanner to scan point clouds of the castings, the castings and the obtained part date were compared and analyzed by computer-aided measurement software. The three-dimension deviations of the casting, the thickness distribution, the important information allowance, the draft angle and so on were obtained, which could provide an important reference data for metal mould casting process and mould design.
