| description |
The effect of the pulse current, pulse on time and pulse off time on the surface roughness of AISI 304 stainless steel workpieces produced by electric discharge machining (EDM) using grade GSP-70 graphite electrodes was studied. A factorial design was performed, considering two levels for each of the three established parameters. From the statistical analysis, it was obtained that the pulse current and pulse on time are the most significant machining parameters on the obtained surface roughness values of the stainless steel AISI 304 workpieces machined by EDM. On the other hand, the regression analysis of a second order model was done to estimate the average roughness (Ra) in terms of the pulse current, pulse on time and pulse off time. Finally, the mean absolute percentage error (MAPE) of the roughness values estimated by the second order regression model and the roughness obtained experimentally is also presented. |

Se realizó un diseño factorial, considerando dos niveles para cada uno de los tres factores establecidos. Del análisis estadístico se obtuvo que la intensidad de la corriente eléctrica y el tiempo de pulso son los parámetros de maquinado más significativos en la rugosidad superficial del acero inoxidable AISI 304 obtenida por MDE. Por otra parte, se hizo el análisis de regresión de un modelo de segundo orden para estimar la rugosidad media (Ra) en términos de la intensidad de la corriente eléctrica, tiempo de pulso y tiempo inactivo. Por último, se presenta el error porcentual absoluto medio (EPAM) de la rugosidad estimada mediante el modelo de regresión de segundo orden y la rugosidad obtenida experimentalmente.application/pdfspaUniversidad Nacional de Colombia - Sede Bogotá - Facultad de Ingenieríahttps://revistas.unal.edu.co/index.php/ingeinv/article/view/67711Universidad Nacional de Colombia Revistas electrónicas UN Ingeniería e InvestigaciónIngeniería e InvestigaciónHERNÁNDEZ CASTILLO, IGNACIO and SÁNCHEZ LÓPEZ, ORQUÍDEA and LANCHO ROMERO, GUILLERMO ARTURO and CASTAÑEDA ROLDÁN, CUAUHTÉMOC HÉCTOR (2018) An experimental study of surface roughness in electrical discharge machining of AISI 304 stainless steel.
