ANÁLISIS DEL PROCESO DE CORTE DE METAL EN UN TORNO CNC, UTILIZANDO DOE y T2 HOTELLING (ANALYSIS OF THE METAL CUTTING PROCESS IN CNC LATHE, USING DOE AND T2 HOTELLING)
Resumen
El objetivo de este trabajo es estudiar los factores de un proceso de manufactura para analizar el impacto que tienen sobre algunas de las variables de respuesta del proceso. En este trabajo se analiza el proceso de corte de metal en un Torno CNC, mediante la implementación de diseño estadístico de experimentos (DOE) y el estadístico T2 Hotelling. Como variables independientes se consideraron tres parámetros de maquinado: el avance, revoluciones por minuto y profundidad de corte. Como variables de respuesta se tomaron los diámetros y el tiempo de procesamiento. Entre los parámetros considerados para este estudio, se encontró que la variable avance, tiene la mayor influencia en la respuesta diámetro. Por otro lado, mediante la aplicación del estadístico T2 Hotelling se llegó a la conclusión de que el proceso está bajo control estadístico.
Palabras Clave: CNC, DOE, T2 Hotelling, variable independiente, variable de respuesta.
Abstract
The goal of this work is to study the factors of a manufacturing process to analyze the impact they have on some of the response variables of the process. This paper analyzes the process of cutting metal in a CNC lathe, through the implementation of statistical design of experiments (DOE) and the statistical T2 Hotelling. As independent variables, three machining parameters were considered: feed rate, revolutions per minute and cutting depth. As response variables, diameters and processing time were taken. Among the parameters considered for this study, it was found that the variable feed rate has the greatest influence on the diameter response. On the other hand, through the application of the T2 Hotelling statistic it was concluded that the process is under statistical control.
Keywords: CNC, DOE, independent variable, response variable, T2 Hotelling.
