En la actualidad, el micro-mecanizado de aleaciones de titanio sigue siendo un gran desafío debido a las propiedades metalúrgicas del material. Esto se ve reflejado en los altos costos de producción en aplicaciones mecánicas, biomédicas, nucleares, químicas y navales. Se propone una metodología estadística basada en el método de superficies de respuesta (RSM) para obtener información sobre el comportamiento de los parámetros de corte en la generación de rugosidad superficial, altura de rebaba y variación de rasgos geométricos de micro-herramienta de corte en operaciones tales como el micro-taladrado convencional, micro-fresado plano y esférico. Lo anterior aplicado sobre aleación de titanio Ti-6Al-4V, adicionando una aproximación a la parte térmica y de micro-deformación en el proceso de corte, complementando finalmente, con un estudio de uso de la mecánica de materiales tradicional al proceso de micro-fabricación de pines por micro-torneado en aleación AISI 12L14. La aplicación de la metodología estadística presentó detalles sobre los parámetros de corte e interacciones entre estos, los cuales tienen marcada influencia en la rugosidad superficial, la altura de rebaba y en los rasgos geométricos de micro-herramienta, tales como: cutting edge radius, major cutting edge, distance apex to end of clearance roundness, minimum distance of edge to apex, minor cutting edge, face, major first flank respectivamente. Las superficies generadas muestran las tendencias de los parámetros de corte para cada atributo evaluado. Se lograron valores preliminares de micro-deformación y tamaño de cristalito por medio del método Williamson-Hall, agregando termografías del proceso de micro-fresado plano. Se obtuvo, con la aplicación del modelo de la mecánica de materiales, para el esfuerzo a flexión de una viga en cantiléver, estimaciones precisas de la ecuación de la curva de la viga elástica en un 60% sobre la longitud en la fabricación de un micro-pin generado por micro-torneado. (Texto tomado de la fuente)Mechanical micro-machining is a prominent micro-fabrication operation in the area of metal cutting, especially when is applied to engineering materials such as titanium alloys. At present, the micro-machining of titanium alloys remains a great challenge due to the metallurgical properties of this type of alloys. This is reflected in the high production costs in mechanical, biomedical, nuclear, chemical and naval applications. A statistical methodology based on the response surfaces method (RSM) is proposed to obtain information on the behavior of the cutting parameters in the generation of surface roughness, burr height and variation of geometrics features of micro-cutting tool in operations such as conventional micro-drilling, flat end-micro-milling and ball end-micro-milling, all above on titanium alloy Ti-6Al-4V, adding an approach to the thermal and micro-deformation part in the cutting process, finally complementing, with the application of traditional materials mechanics to the micro-manufacturing process of pins by micro-turning in AISI 12L14 alloy. The statistical methodology application revealed which cutting parameters and interactions between them significantly affect surface roughness, burr height and geometric features of the cutting micro-tool, such as: cutting edge radius, major cutting edge, distance apex to end of clearance roundness, minimum distance of edge to apex, minor cutting edge, face, major first flank respectively. The generated surfaces show the trends of the cutting parameters for each attribute evaluated. Preliminary values of micro-strain and crystallite size were achieved by the Williamson-Hall method, adding micro-milling process thermographs. With the material mechanics model application for the cantilever beam bending, precise estimates of the elastic beam curve equation were obtained in 60% on the length in the manufacture of a micro-pin generated by micro-turning.MaestríaMagíster en Ingeniería - Materiales y ProcesosMeso/micro-maquinado multi-ejes CNCxvi, 92 páginasapplication/pdfspaUniversidad Nacional de ColombiaBogotá - Ingeniería - Maestría en Ingeniería - Materiales y ProcesosDepartamento de Ingeniería Mecánica y MecatrónicaFacultad de IngenieríaBogotá, ColombiaUniversidad Nacional de Colombia - Sede Bogotá670 - Manufactura::671 - Proceso de metalurgia y productos metálicos primarios680 - Manufactura para usos específicos::681 - Instrumentos de precisión y otros dispositivosMáquinas en la industriaIndustrial equipmentMicro-maquinadoTitanio Ti-6Al-4VAISI 12L14Método de Superficie de RespuestaMecánica de materialesMicro-machiningTi-6Al-4V titanium12L14 SteelSurface Response MethodMaterials mechanicsMicro-maquinado multi-ejes CNC aplicado a implantes dentales en aleación de Titanio Ti-6Al-4VMulti-axis CNC micro-machining applied to dental implants in titanium alloy Ti-6Al-4VTrabajo de grado - Maestríainfo:eu-repo/semantics/masterThesisinfo:eu-repo/semantics/acceptedVersionTexthttp://purl.org/redcol/resource_type/TM[1] J.
