In the digital processing of mould, this paper presents a new method to improve the accuracy of the edge of mould with optical scanners and three coordinate measuring machine. According to researching lots of IGES files of CAD/CAM systems, this paper presents a method for transforming reference point datum to IGES file. The processing system can transform the data measured in different coordinate systems into one coordinate system based on the theory that three datum points construct an orthogonal coordinate system. There is no distortion in mould because of the rigid transform. Also the processing quality is guaranteed.
