非整圆回转零件测量过程中修正偏心影响的研究

Research on Modifying the Eccentric Effect in Mesuring the Rotating of Non-complete Circle

在测量以凸轮为代表的非整圃回转零件时，若转动中心偏离工件几何中心，就会给某些重要参数的测量结果带来误差。本文对测量过程进行了数学描述，并经严谨椎导建立了偏心修正的数学模型。

In measuring the rotating parts of non-complete circle like cam there would be the measurement error if the ro tating centres deviate from the geometrie centres of parts. This paper describse the measuring process theoretically, and deduces the mathematical mode] about modifying the eccentric effect.
