Abstract

SE PROPONE UN METODO PARA MANUFACTURAR UNA HERRAMIENTA (1) QUE SE USARA PARA OBTENER CONFORMACIONES (4) EN FORMA DE REBORDES (12), TACOS, CELDAS Y REBORDES DE SECCION DE CORTE TRIANGULAR SOBRE LA SUPERFICIE DE UNA PIEZA EN BRUTO (15). EL METODO PROPUESTO FACILITA LA SELECCION DE LOS PARAMETROS GEOMETRICOS DE LA HERRAMIENTA (1) Y DEL MODO DE MANUFACTURACION PARA OBTENER PROYECCIONES (12) DE INTERVALOS PREDETERMINADOS Y DE UNA ALTURA Y UN ANGULO DE INCLINACION PREDETERMINADOS. LA ANCHURA DE LOS ESPACIOS ENTRE LAS PROYECCIONES PUEDE VARIARSE ENTRE UNIDADES DE MILIMETROS Y UNIDADES DE MICROMETROS. EL METODO NO PRODUCE DESECHOS Y ES ALTAMENTE EFICIENTE, REQUIERE SOLAMENTE UN EQUIPO SIMPLE Y PUEDE UTILIZARSE PARA OBTENER SUPERFICIES DE EVAPORACION Y DE INTERCAMBIO DE CALOR, PRODUCIR ESTRUCTURAS CAPILARMENTE POROSAS EN TUBOS TERMICOS Y FILTROS DE RANURAS FINAS, PARA OBTENER CAPAS GRUESAS, COMPUESTAS SOBRE LAS SUPERFICIES DE COMPONENTES, ROSCAS DE MAQUINAS O SUPERFICIES DE TRATAMIENTO QUE SUFRAN UNROCIADO DE PLASMA, UN PEGADO O UN SOLDADO POR DIFUSION. LA INVENCION PUEDE UTILIZARSE EN LA CONSTRUCCION DE MAQUINAS EN GENERAL Y EN LA GENERACION DE ENERGIA, EN EL AREA DE LA QUIMICA, DE LA REFRIGERACION Y DE LA INGENIERIA CRIOGENICA.
