Abstract

EL PROCEDIMIENTO OPTICO DE CONTROL DE LAS PERFORACIONES (5,9) DE UNA PALETA HUECA DE TURBOMAQUINA SEGUN EL INVENTO, ESPECIALMENTE LAS PERFORACIONES REALIZADAS JUNTO AL BORDE DE ATAQUE O BORDE DE SALIDA DE LA PALETA, SE CARACTERIZA PORQUE: SE ILUMINA, MEDIANTE UNA FUENTE LUMINOSA (10), LA CAVIDAD INTERNA (4,6) DE LA PALETA A TRAVES DEL CANAL (7) PRACTICADO EN EL PIE DE LA PALETA; SE BARRE LA LONGITUD DE LA PIEZA MEDIANTE UNA CAMARA VIDEO (13) Y SE REGISTRA LA LUMINANCIA DE LOS RAYOS REFLEJADOS QUE HAN ATRAVESADO LOS ORIFICIOS (5,9) DE LA PIEZA A CONTROLAR; SE TRANSFORMA LA SERIE DE INFORMACIONES RECOGIDAS DE ESTE MODO EN SEÑALES ELECTRICAS; SE MEMORIZAN DICHAS SEÑALES EN UNA UNIDAD DE CALCULO (15) Y DE MEMORIZACION; SE TRATAN DICHAS SEÑALES Y SE LAS COMPARA CON UN TREN DE SEÑALES DE REFERENCIA PREDETERMINADO A PARTIR DE UNA PIEZA DE CALIBRADO. APLICACION EN LA AUTOMATIZACION DE METODOS DE CONTROLES.
