Temperature assessment in the drilling of ex vivo bovine and porcine cortical bone tissue
| Resumo: | Thermal damage in boné tissue is a common problem in drilling processes. The main goal of this work is to analyze the cutting conditions that generate the lower temperature, avoiding the occurrence of thermal boné necrosis. In this work, the effects of the drill speed and the feedrate were studied during the drilling ofcortical bovine and porcine boné tissue. !n the ex vivo drilling operations, two methodologies were performed on several fresh femur boné samples. The present study showed that the combinations of cutting conditions in the drilling process of ex 1//Vo cortiça! bovine and porcine boné tissue, produced temperatures far below the criticai values. It was concluded that the temperature increases with an increasing drill speed and decreases with high feed-rates. To the drill speed, the difference is less clear than that the the feed-rate. The drilling temperatures on the bovine samples were higher than porcine samples. |
