Research on Detecting Tap Wear in Vibratory Tapping by Using Dynamic Signal

分析了动态切削力研究的理论依据及在计算机中的实现方法；研究了振动攻丝动态攻丝扭矩与丝锥磨损的关系；提出了在频域内采用动态攻丝扭矩主要峰值频率的功率值实时检测丝锥磨损的方法。

In this paper the theory for studying the dynamic force and the method for implementing in the computer are analyzed. The relationship between the dynamic tapping torque and the tap wear is studied through the experiments. The power magnitude of main peak frequency of dynamic tapping torque can be used for on_line detecting the tap wear.
