本文列出了攻钛合金螺纹时,丝锥几何参数影响切削扭矩和螺帽螺纹中径的研究结果。用丝锥攻钛合金螺纹时,对扭矩和螺帽螺纹中径影响最大的是:螺纹型面侧后角,切削锥角和切削锥后角。本文还确定了丝锥的最佳几何参数。
This article lists the results of studies on the influence of taps geometric parameters on cutting torque and nut thread diameter when tapping titanium threads. Taps tapping alloy thread, the torque and the largest impact on the screw thread diameter is: thread profile after the corner, cutting cone angle and cutting cone clearance angle. This article also determines the best geometric parameters of the tap.
