A method for predicting the thrust and torque in vibration microdrilling is proposed. The model is based on the mechanics of vibration cutting analysis, which involves the development of a dynamic uncut chip thickness analysis for each vibration cutting element at the lips and chisel edge. The proposed method has been tested for a range of vibration parameters and feeds. The predicted thrust and torque values have been compared with those obtained in vibration microdrilling experiments. These comparisons showed good agreement between the theoretical predictions and the experimental evidence.
