2) friction torque
摩擦扭矩
1.

2.
It was found that the friction torque was about 45% of the total torque as tapping with the standard taps.
结果表明,标准丝锥对GH4169攻丝的摩擦扭矩占总扭矩的45%,其顶后刀面及侧后刀面沿切削速度方向出现严重的磨损沟和粘着物,这主要归因于GH4169中的硬质点和严重的加工硬化;同标准丝锥相比,修正齿丝锥的摩擦扭矩减小65%,且磨损显著减轻,这是由于其独特的渐成法成形有利于减小刀齿与被切螺纹侧面间的摩擦接触面积及被切螺纹因大弹性变形而夹住丝锥齿的可能性所致。
