Abstract—The drilling operation is considered by manufacturers as complex and difficult process (rapid wear of the cutting edge as well as problems of chip evacuation). Faced with these failures, manufacturers have shifted in recent years towards the drilling process assisted by forced vibrations. This method consists to add an axial oscillation with a low frequency to the classical feed movement of the drill so as to ensure good fragmentation and better chip evacuation.

This paper presents a model for prediction of cutting forces and torque during a drilling operation assisted by forced low-frequency vibration of titanium alloy Ti6Al4V. The model allows understanding the interaction between the tool and the workpiece and numerically identifying the thrust cutting force and torque generated by the vibratory drilling operation. The effects of cutting and tool parameters on the thrust cutting force and drilling torque will be discussed.
