摘要
工业CT(显微计算机断层扫描系统)能够生成被检铸件的断层扫描图像,并通过VG Studio软件重建铸件的三维模型,能够对铸件内部缺陷的空间位置、尺寸大小、孔隙率等进行测量;可以将三维图纸与三维模型进行尺寸比对,并进行偏差分析;根据三维拟合模型,借助逆向生成软件,可以实现对铸件图纸的逆向生成。简要介绍了工业CT的工作原理、最优扫描参数设定的依据、几种常见的铸件内部缺陷以及三维尺寸比对应用的实例分析。
Industrial CT can produce the scanning images of the detected castings, Rebuild the casting 3D modelthrough VG Studio software, It can detect the space position of casting defect, Measure size and porosity. Industrial CTcan compare 3D drawings with 3D models and analysis deviation. According to the 3D model, in virtue of reversegenerated software, You can reverse engineer the drawing.This paper introduces briefly the imaging principle of IndustrialCT, The basis of optimal scanning parameter setting, Several common defects in castings, 3D size comparison caseanalysis.
