Theoretical and Experimental Research on Tapping Forces of Nickel-Based Superalloy GH4169

Abstract:

The mechanical model of the tapping torque and the friction one were established based on Theoretical Research of Tapping Forces. A series of standard taps with a cutting cone angle of 7°30′ were prepared from high-speed steel W9 and used to tap Nickel-based superalloy GH4169.It was found that the friction torque was about 45% of the total torque as tapping with the standard taps. Friction torque is the main reason in tapping difficult –to-cut materials.
