This article mainly introduces the method that adopts gear caliper to measure the median diameter normal tooth thickness of double-line trapezoidal thread.
本文主要介绍了采用齿轮卡尺测量双线梯形螺纹中径法向齿厚的方法,同时也测量出螺距产生的误差。
In addition, they believe, for tapping there exists a critical cutting thickness (thread depth) value of the critical cutting thickness within the tapping can reduce the tapping torque.
此外,他们认为,对于攻丝存在一个临界切削厚度(螺纹深度)值,在临界切削厚度的范围内,攻丝能降低攻丝扭矩。
