thread form

Effect of the front angle of thread turning tool on the thread form angle is studied when manufacturing the thread.

研究了刃磨前角的刀具在加工螺纹时对牙型角的影响,以及采用修正前面内刀尖角的方法进行补偿,保证牙型角的精确性,在加工韧性材料时不产生振刀现象。

Based on the thread measuring principle with three-pins method,the relationships among main internal thread parameters were investigated,and a measuring device for internal thread parameters such as intermediate diameter,thread form angle and pitch was designed,it is suitable for general thread,trapezoid thread and serrated thread.

基于"三针法"螺纹测量原理,研究了内螺纹主要参数之间的相互关系,设计了可测量普通螺纹、梯形螺纹、锯齿形螺纹等内螺纹的中径、牙型角和螺距的测量装置。
