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。
Metal mold casting R & D process, casting only in the case of physical conditions, the exact size of the casting is to develop process planning and design of the basic requirements of the mold. In this paper, a three-dimensional scanning of the metal mold casting was carried out using a three-dimensional scanner to obtain the point cloud of the casting, and the three-dimensional comparative analysis of the casting and the part number and mold was carried out by computer-aided measurement software. Obtained the casting dimensional deviation, wall thickness distribution, allowance, draft and other important information. For the metal mold casting process and mold design provides an important reference data.
