Abstract

SE PROPORCIONA UN INSERTO PARA USO EN EL EXTREMO DE UNA FRESA DE BOCA ESFERICA (1), QUE INCLUYE UN CUERPO DE INSERTO (22) CON UNA PARED SUPERIOR (24), UNA PARED INFERIOR (28) Y POR LO MENOS UNA PARED LATERAL CURVADA (30). SE DETERMINA UN FILO CURVADO (34) POR LA INTERSECCION ENTRE LAS PAREDES SUPERIOR E INFERIOR, QUE INCLUYE UNA PLURALIDAD DE ONDULACIONES SINUSOIDALES (36) PARA REDUCIR LAS FUERZAS DE CORTE Y LA VIBRACION, Y MEJORAR LA RUPTURA Y EXTRACCION DE VIRUTAS ARRANCADAS DE LA PIEZA (66) DURANTE UNA OPERACION DE CORTE. UNA PARTE EXTREMA (67) DEL INSERTO, CRUZA EL EJE DE ROTACION (A) CUANDO EL INSERTO ESTA MONTADO EN EL ASIENTO DEL CUERPO DEL EXTREMO DE UNA FRESA (3), Y LAS ONDULACIONES (36) REDUCEN LOS CONSIDERABLES ESFUERZOS CORTANTES APLICADOS AL FILO (34) EN ESTE PUNTO. EL FILO TIENE UN PERFIL QUE SIGUE EL CONTORNO DE UN ESFERA, PARA PERMITIR FRESAR UN CORTE REDONDEADO. LA PARED LATERAL (30) DEL CUERPO DEL INSERTO, INCLUYE UNA PARTE SUPERIOR DE DESTALONAMIENTO (44) DIRECTAMENTE DISPUESTA SOBRE EL FILO, CON UN ANGULO DE DESTALONADO PARA IMPEDIR QUE LAS ONDULACIONES REALICEN ESTRIAS O MARCAS DE HERRAMIENTA INDESEADAS, EN LAS PAREDES LATERALES DEL CORTE REDONDEADO.
