样板加修正与渐开线仪器测量准确度的研究

Research on template adding correct and involute tester measuring accuracy

渐开线仪器采用样板加修正的方法，可以消除由于仪器基圆半径不准确等因素产生的仪器系统误差，并统一渐开线仪器量值，提高仪器准确度。文中论述了正确使用渐开线样板的方法，以及对基圆半径差的线性修正方法。

The system error of involute testerdue to uncorrect basic round radius,etc.canbe eliminated by a template added with correction to standardize the measured value of involute tester and to improve its accuracy. In thearticle, the way to correctly using involutetemplate and how to make a linear correctionon basic round radius difference.
