Resumen

En este artículo se presentan resultados de una investigación llevada a cabo en micromecanizado de polímeros biocompatibles. Se describen los procesos de fabricación de micropartes con el fin de mostrar los niveles de precisión y escalas dimensionales alcanzables con un centro de micromecanizado Kern Evo. Adicionalmente, se muestran los resultados de una serie de pruebas de microcorte realizadas con fresas de tungsteno de 100 m de diámetro sobre probetas de PMMA (Polimetilmetacrilato), grado médico para determinar los parámetros que minimizan el tamaño de las rebabas generadas. Para caracterizar tanto superficies generadas, como condiciones iniciales y finales de las herramientas se emplearon técnicas de microscopía óptica y electrónica. Los resultados referentes a las primeras pruebas de mecanizado indican que en el control de las características dimensionales se deben vigilar aspectos como la profundidad de corte establecida, el método de sujeción seleccionado y la tolerancia de alineación de la pieza; incluso deben controlarse las condiciones ambientales del recinto donde opera el equipo.
