摘要

An improved model to calculate the force characteristics (i.e. axial thrust force and torque) of the bone tissue drilling process is presented. The model makes use of theoretical and experimental data and is based upon the cutting work concept. It takes into account the heterogeneity of the bone material and the effects of contact indentation and delayed bone chip evacuation on the axial force and torque during bone drilling. The proposed model has shown to accurately predict the force characteristics in all stages of the drilling process.
