ABSTRACT

Material removal through the drilling mvolves two important processes. The fírst one is drilling of material by cutting edges ofthe drill bit and the second one is the fi-iction generated by the contact between drill bit and hole wall of the material. Both processes lead to heat generation during drilling. In clinicai practice, drilling procedures and high-speed cutting tools are often applied on boné tissue. These operations are associated to complications such as thermal osteonecrosis due to the excessive heat generation and mechanical damage due to the excessive leveis of penetration force. The development of additional tools for accurately simulating the drilling is essential to predict the risk of thermo-mechanical damage during boné drilling. This paper investigates the thermal and mechanical damage in boné tissue induced by different parameters. An experimental and numerical approach of boné drilling hás been conducted. A three-dimensional dynamic numerical model was developed to simulate the mechanical and themial stresses generated during the drilling. The numerical model incorporates the geometrical and dynamic characteristics involved in the drilling processes. The numerical analysis hás been validated by experimental tests using polyurethane foam materiais with similar mechanical properties to the human boné.

Keywords: Boné drilling, damage, experimental testing, numerical modelling.

INTRODUCTION

Drilling is one of the most írequent conventional mechanical processes in machining operations. The industrial concepts of productivity and surface integrity in material removal processes can be translated to medicai applications. In this context, reduced drilling time is related to short surgery global time and boné integrity is related to the absence of drilling induced damage (Marco el al. 2015). The common problems associated with the drilling are thermal and mechanical damage due the excessive heat and the cut effort achieved during the process, (Augustin et al. 2008; Fernandes et al. 2015).

Clinicai problems such as implant failures have been reported on the literature and are associated with the thermal and mechanical damage which occur during the drilling (Agustin et al. 2008). The importance of this problems have motivated the development of different methodologies. However, it is difficult to draw definitive conclusions due to the wide variety of involved parameters, such as the tool geometry and drilling parameters.

The development ofaccurate numerical models can help in the understanding of boné drilling and thus in the analysis and defínition ofdrilling operations in boné tissues.

5"' International Conference on Integrity - Reliability - Failure

This study presents a three-dimensional dynamic thermomechanical model to simulate the

thermal stresses during boné drilling. The numerical model was validated with experimental

tests performed on polyurethane foam materiais instmmented with strain gauges to measure

the strains and thermocouples to measure the temperature distribution inside the blocks

(Figure l). Also, the temperatures on the drill bit and block surfaces were measured with a

thermal camera. The effects of some drilling parameters, such as drill speed and feed-rate

were studied.

Fig. l - Experimental and numerical model of boné drilling. RESULTS AND CONCLUSIONS

A three-dimensional elastic plastic dynamic model to simulate the drill bit penetration into the

boné tissue was developed. Thermal stresses involved in the drilling processes were obtained

and compared with experimental tests. The results show that thermal stresses generated in the

material tend to increase with tool penetration. The numerical results are in good agreement

with experimental results. The proposed numerical model can be used to simulate the

behaviour boné during the drilling process, considering different parameters.
