Abstract
CONJUNTO DE ROTOR Y PALETAS DE TURBOMAQUINAS. PUEDEN USARSE MAYORES HERRAMIENTAS CORTADORAS QUE TENGAN INHERENTEMENTE MAYOR RESISTENCIA PARA FORMAR RANURAS DE MONTAJE PARA PALETAS DE ROTOR DO ENTRADA LATERAL CUANDO, EN EL PROCESO DE MECANIZACION, SE INCREMENTA EN ANCHURA EL CUELLO MAS PROFUNDO DE LA RANURA. LA MAYOR ANCHURA DEJA UN ESPACIO LIBRE A AMBOS LADOS DEL CUELLO MAS PROFUNDO DEL PIE EN UN PUNTO ALEJADO DE LAS SUPERFICIES SOPORTANTES DE CARGA.
