Abstract
SE TRATA DE UN METODO PARA PRODUCIR RAICES (23) DE ALABES DE TURBINA QUE UTILIZA UN APARATO DE MECANIZAR POR ELECTRODESCARGA PARA EL MECANIZADO DE PARTES CRITICAS DE LA RAIZ (23) DE ALABE, SEGUIDA POR EL MARTILLADO DE LAS PARTES MECANIZADAS. EL MECANIZADO POR ELECTRODESCARGA DE LA RAIZ DE ALABE DEJA CAPAS REFUNDIDAS EN LA SUPERFICIE DE LA RAIZ (23) DE ALABE, Y SE ENCUENTRAN GRANDES ESFUERZOS DE TRACCION RESIDUALES EN LA SUPERFICIE DE LA RAIZ (23) DE ALABE, QUE PUEDEN PROVOCAR LA PROPAGACION DE GRIETAS. EL MARTILLADO DE LAS SUPERFICIES MECANIZADAS DEJAS ESFUERZOS DE COMPRENSION RESIDUALES CERCA DE LA SUPERFICIE Y REDUCE LAS CAPAS REFUNDIDAS. LA RAIZ (23) DE ALABE RESULTANTE CUMPLE LAS MISMAS ESPECIFICACIONES DE DURABILIDAD Y TOLERANCIAS QUE UNA RAIZ DE ALABE MECANIZADA EMPLEANDO EL PROCEDIMIENTO CLASICO DE CORTE DE TIPO DE LINEA EN CADENA, PERO CON UNA FRACCION DEL COSTO.
