Finite Element Analysis of the Process of Drilling Medical Titanium Sheet

摘要

This article showed that the research of the process of drilling medical titanium sheet. Internal stress, strain and temperature distribution could not be seen, so based on Finite element analysis software, establishing finite element model of the process of drilling. On the basis of the inspection and studying existing drilling technology, three options were proposed. In view of stress, strain, temperature, and axial force, analyze the process of drilling titanium sheet. The results showed that penetration rate in 1000 r/min and feed in 0.04 mm/r, twist drill drilling medical titanium sheet is more reasonable.
