用基面旋转法评定平面度误差

Evaluating Error of Planeness by Use of Rotating Datum Plane

介绍利用基面旋转法建立被测平面的理想要素即评定基面的方法和步骤 ,从而求出被测平面对理想要素的变动量 。

The ideal elements of plane that be measured such as method and step of evaluating datum plane were build by use of rotating datum plane were introduced. The changed value of ideal elements for measured plane was error of planeness.
