摘　　要：分析了振动攻丝的实现方式及其运动原理。基于振动攻丝的动态角位移方程得出丝锥最大偏转角和攻丝扭矩的关系式,并给出了净切削时间比和振动圆频率对丝锥最大偏转角的影响规律,丰富了振动攻丝丝锥刚性化机理。Comparative to custom tapping method, vibration tapping improve the tap rigidity. So, it is necessary to study the rigidity mechanism of tap in vibration tapping. Firstly, based on dynamic model of vibration tapping, this paper deduce the relation expressing between maximum deflection angle and tapping torque . Secondly, this paper analyze how the clean cutting time and vi- bration frequency impact on maximum deflection angle and drew some valuable conclusions which enrich the tap rigidity mechanism in vibration tapping.

关 键 词：振动攻丝 最大偏转角 刚性化
