Resumen
Los actuales procesos de conformación mecánicos, utilizados en la fabricación de dispositivos Ti6Al-4 V ELI quirúrgicos, crean un efecto microestructural que reduce las propiedades mecánicas del material, lo que afecta su rendimiento en circulación. En este trabajo se estudia el efecto de la microestructura que tiene lugar en el proceso de corte de Ti6Al-4 V ELI con el objetivo de seleccionar las mejores condiciones de corte disponibles para las necesidades de la empresa Quirúrgicos Especializados. El proceso de corte ofrece dos condiciones que controlen la rotación y la velocidad de avance lineal en la herramienta de corte. Para este trabajo cortamos 6 muestras de Ti6Al-4 V ELI; cada muestra tuvo diferentes condiciones para ser analizados metalográficamente mediante microscopía óptica. Se observó una modificación de la microestructura Ti6Al-4 V ELI y se ha estimado un efecto cualitativo sobre las propiedades mecánicas, lo que permite seleccionar las condiciones más eficientes en el proceso de corte.
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.
