Abstract
POR EJEMPLO UN CANAL LONGITUDINAL (2) DE ELECTRODOS DE METAL DURO PARA ELECTROEROSION (1) SE REALIZA EN LUGAR DE CON UNA SECCION CIRCULAR CON UNA SECCION PARCIALMENTE ESTRECHADA CON EL FIN DE EVITAR QUE SE FORMEN TETONES QUE CRECEN HACIA EL INTERIOR DEL CANAL LONGITUDINAL, POR EJEMPLO DURANTE LA EROSION DE PENETRACION O DURANTE EL TALADRADO DE AGUJEROS DE INICIO PARA LA ELECTROEROSION POR HILO. SE TRATA PREFERENTEMENTE DE UN UNICO CANAL DE LIQUIDO DE BARRIDO, QUE TRANSCURRE EN PARTICULAR CENTRADO. LA SECCION SE CARACTERIZA POR LA DISTANCIA MINIMA R SUB,MIN (10) Y LA DISTANCIA MAXIMA R MAX (9) ENTRE LA PAR ED DEL CANAL Y EL CENTRO DE GRAVEDAD DE LA SECCION, QUE ES COMO MINIMO DE 0.01 R MAX . LAS VERSIONES PREFERIDAS DE SECCION SON SECCIONES QUE TIENEN APROXIMADAMENTE FORMA DE TREBOL CON SIMETRIA ANGULAR DE 3, 4 O 5 REPETICIONES. TAMBIEN EXISTE LA POSIBILIDAD DE REALIZAR CON TALES SECCIONES, UNO HASTA TODOS LOS CANALES DE LOS ELECTRODOS DE METAL DURO PARA ELECTROEROSION DE CANALES MULTIPLES.
