• Resumen

  • Current mechanical forming processes used in the production of surgical Ti6Al-4V ELI devices create an undesired microstructural effect that reduces the mechanical properties of the material, thus affecting its performance while in service. In this work we study the microstructural effect that take place in the cutting pro- cess of Ti-6Al4V ELI with the goal of selecting the best available cutting conditions for Quirúrgicos Especial- izados company needs. The cutting process offers two conditions to control rotation and lineal feed speed in the cutting tool. For this work we cut six samples of Ti- 6Al-4V ELI, each sample had different conditions to be metallographically analyzed via optical microscopy. We observed a modification on the Ti-6Al-4V ELI microstruc- ture and a qualitative effect on the mechanical proper- ties have been estimated, allowing the selection of the more efficient conditions in the cutting process.
