Abstract
El acero inoxidable dúplex UNS S32205, por sus propiedades mecánicas, es un material de difícil maquinado, incluso para el proceso de fresado final, representando un gran desafío para las industrias, principalmente petroleras, que fabrican piezas y equipos para cumplir con sus condiciones de operación con éxito. Este trabajo tiene como objetivo determinar los parámetros óptimos del proceso de fresado final utilizando el método "Análisis relacional de grises" (GRA). Para planificar los experimentos se utilizó la matriz ortogonal L16 (2³) de Taguchi. Las variables de control utilizadas fueron velocidad de corte (vc), penetración de trabajo (ae), avance por diente (fz). La profundidad de corte (ap) se mantuvo constante en 1 mm en todos los experimentos realizados. Las respuestas analizadas fueron rugosidad superficial Ra y Rt, tasa de remoción de material (MRR), poder de corte (Pc). Los parámetros óptimos determinados por el GRA demostrando la eficiencia del método utilizado.
UNS S32205 Duplex Stainless Steel, due to its mechanical properties, is a material of difficult machinability, including for the end milling process, representing a great challenge for industries, mainly oil companies, which manufacture parts and equipment to meet their operating conditions successfully. This work aims to determine the optimal parameters of the end milling process using the “Grey Relational Analysis” (GRA) method. To plan the experiments, the orthogonal matrix L16 (2³) of Taguchi was used. The control variables used were cutting speed (vc), radial depth of cut (ae), feed per teeth (fz). The depth of cut (ap) remained constant at 1mm in all experiments performed. The analyzed responses were surface roughness Ra and Rt, material removal rate (MRR), cutting power (Pc). The optimal parameters determined by the GRA proving the efficiency of the method used.
