DELCAM的老用户可能都知道在PM最初的版本里面输入模型的时候会出现一个参数设置“三角化公差”。在3.0版本以前上述表格中的“模型输入公差数值为0.01”从PM3.1版本数值可以设置为0.001,我们注意what's new里面的相关解释“Tolerance Improvements
The default importation tolerance has been reduced from 0.01 (or 0.001 for imperial units) to 0.001 ( or 0.00004 for imperial units). This ensures that the model can be prepared successfully for subsequent machining
operations.”
