在PWF-250滚刀检查仪及其它同一原理的仪器上,用圆形测量直线型螺旋面蜗杆的问题,本刊文[1]和文[2]曾先后进行了探讨。本文将进一步探讨这一问题,并提出测量误差的近似计算方法。
In the PWF-250 hob tester and other instruments of the same principle, the problem of measuring circular helical worm with a circular shape has been discussed in this paper [1] and [2]. This article will further explore this issue and propose an approximate calculation of measurement error.
