Bone drilling: an identification of heat sources

Abstract : During every machining operation, a part of the energy necessary to cut dispels into heat. Heat is associated with the plastic deformation in the different shear zones (even for bone tissues; Liao and Axinte 2016), and with the frictional dissipation energy generated at the tool-chip interface and at the interface between tool and sample. During surgery, bone drilling leads therefore to an increase of temperature that can potentially cause osteonecrosis, if the level of temperature and/or the duration of exposition is too high. The recent work of Feldmann et al (2018) showed that the heat conductivity of bone tissues is highly dependent on the bone volume fraction. As this volume fraction is varying locally inside bone tissues, a systematic experimental campaign allowing to identify the heat sources during drilling is hard to conduct. To counter this difficulty, a homogeneous and porosity-controlled material is used in the present experimental work to identify the causes of the thermal loading into the sample. The results of the experiments will allow to improve the analytical model previously developed (Amewoui et al. 2019) for predicting the temperature during bone drilling.
