Modeling of maximum torque in vibration tapping

The selection of vibration tapping parameters plays a very important role in vibration tapping, which is generally obtained through a lot of single factor experiments. This method takes much time and is much costly, which seriously cumbers the application of vibration tapping technology. It is very necessary to find some simpler method to solve the problem. In this paper, a new formula was proposed to describe the relation between the cutting number of times (CNT) and the rebound thickness (RT). Based on the formula and the repeat-cutting theory (RCT), a mathematical model was established to calculate the maximum tapping torque in vibration tapping. A simulation was carried out to verify the model, and the simulation result is proved to have good match with the experimental result. The model can be used to improve and simplify the selection of vibration tapping parameters.
