Effects of cutting parameters on surface roughness and hardness in milling of AISI 304 steel

This paper presents an experimental study in dry milling of austenitic AISI 304 stainless steel with hard alloy milling cutters, related to the influence of feed rate and cutting speed on surface roughness and hardness. The results show that machining caused a decrease in hardness of the workpiece w...

Los resultados muestran que, el maquinado provocó una disminución de la dureza de la pieza con relación a la pieza inicial, no obstante, el avance y la velocidad de corte no representaron efectos estadísticamente significativos para el nivel de confianza establecido. Los menores valores de rugosidad superficial se obtuvieron para las mayores velocidades de corte y para los menores avances, siendo la velocidad de corte el factor de mayor contribución. El modelo de regresión múltiple fue calculado y se comprobaron los requisitos para plantear que las variables están correlacionadas. Finalmente, se determinaron los parámetros de corte más adecuados utilizando el gráfico de contorno.application/pdfspaUniversidad Nacional de Colombia - Sede Medellín - Facultad de Minashttps://revistas.unal.edu.co/index.php/dyna/article/view/64798Universidad Nacional de Colombia Revistas electrónicas UN DynaDynaHernández González, Luis Wilfredo and Pérez-Rodríguez, Roberto and Quesada-Estrada, Ana María and Dumitrescu, Luminita (2018) Effects of cutting parameters on surface roughness and hardness in milling of AISI 304 steel.
