摘　　要：用三维扫描仪对实型铸件进行三维扫描,获取了铸件点云,用计算机辅助测量软件对铸件和CAD模型进行了3D和2D比较分析。结果发现,实型铸件存在内腔外胀、整体偏移、壁厚不够、孔位偏移等缺陷。结合三维检测结果,进行了工艺分析并提出了对应措施。The point cloud of the expendable pattern castings was picked out with the three dimension scanner. Three dimension and two dimension comparison between the castings and the final CAD model was conducted by a computer aided inspection software. The results reveal that there exists cavity dwell- ing, pattern shift and wall-thickness lass as well as hole position shifting. Based on 3D inspection, the count-measures were suggested.
