三坐标扫描测量技术在模具设计和制造中的应用

The application of three coordinate scanning measuring technique in mold design and manufacture

简要介绍了接触式与非接触式扫描测量的特点和PC-DMIS软件中几种扫描物体的方法，并以闭线扫描法为主，基于SP600扫描测头对模具设计与制造中的实物进行了测绘应用，表明了接触式扫描测量在高精度测量应用中的优势。

The several ways of scaning in PC-DMIS was introduced briefly, the accuracy, speed and application range of touched and non-touched scanning technology are analysed and compared. Moreover, the application of touched scanning technology based on coordinate measuring machine（CMM） used for mould design and manufacture was presented with measurement example .
