Abstract

SE DESCRIBE UN PROCEDIMIENTO PARA RECTIFICAR UNA PIEZA COMPUESTA (18) A FIN DE OBTENER UN COMPONENTE QUE TENGA FORMAS CILINDRICAS CONCENTRICAS (31) Y EXCENTRICAS (30). EL PROCEDIMIENTO COMPRENDE MONTAR LA PIEZA (18) EN UNA MAQUINA RECTIFICADORA CONTROLADA POR ORDENADOR (10) QUE TIENE UNA MUELA DE RECTIFICAR (12) CUYO AVANCE Y RETIRADA PUEDE CONTROLARSE POR MEDIO DE UN PROGRAMA INTRODUCIDO EN EL ORDENADOR DE CONTROL (32), LA CARGA EN EL ORDENADOR DE UN PROGRAMA PARA CONTROLAR EL AVANCE LA MUELA, CON POSICIONAMIENTO RELATIVO DE LA MUELA RECTIFICADORA Y DE LA PIEZA PARA ALINEAR LA MUELA CON UNA PRIMERA ZONA SELECCIONADA DE LA PIEZA, EL AVANCE DE LA MUELA RECTIFICADORA EN DIRECCION A LA ZONA SELECCIONADA A FIN DE RECTIFICAR SU SUPERFICIE, EL CONTROL DE AVANCE DE LA MUELA, A FIN DE MANTENER EL CONTACTO RECTIFICADOR ENTRE LA MUELA Y LA PIEZA, A FIN DE RECTIFICAR UNA ZONA CILINDRICA CONCENTRICA DE LA MISMA O UNA ZONA CILINDRICA EXCENTRICA (DESVIADA) DE ELLA, SEGUN SE REQUIERA, ALMACENANDOSE EN ELORDENADOR INFORMACION SOBRE CADA ZONA SELECCIONADA DE LA PIEZA, Y DIRECCIONANDOSE, SEGUN SEA APROPIADO, DE MANERA QUE PUEDA CONTROLARSE EL AVANCE DE LA MUELA SEGUN QUE LA ZONA DE LA PIEZA SELECCIONADA DEBA RECTIFICARSE EN FORMA DE ZONA CILINDRICA CONCENTRICA O EXCENTRICA (DESVIADA). EL PROCEDIMIENTO PERMITE QUE PUEDAN RECTIFICARSE TANTO LAS ZONAS CILINDRICAS CONCENTRICAS COMO LAS EXCENTRICAS (DESVIADA) DE LA PIEZA CON EL USO DE UNA SOLA RECTIFICADORA BAJO CONTROL DE ORDENADOR, SIN TENER QUE DESMONTAR LA PIEZA DE LA MAQUINA. EL PROCEDIMIENTO COMPRENDE IGUALMENTE LA INTRODUCCION DE PEQUEÑOS MOVIMIENTOS DE AVANCE Y RETRACCION DEL AVANCE DE LA MUELA MIENTRAS ESTA ULTIMA ESTA DEDICADA A RECTIFICAR UNA ZONA CILINDRICA CONCENTRICA DE LA PIEZA, A FIN DE INTRODUCIR EN LA ZONA QUE SE ESTA RECTIFICANDO UNA EXCENTRICIDAD QUE SEA IGUAL Y OPUESTA A CUALQUIER EXCENTRICIDAD QUE LAS FUERZAS DEL PROCESO DE RECTIFICADO INTRODUZCAN EN LA REGION RECTIFICADA, DE MANERA QUE LAS DOS EXCENTRICIDADES SE ANULEN ENTRESI. SE DESCRIBE UNA MAQUINA RECTIFICADORA CONTROLADA POR ORDENADOR ASI COMO LOS PROGRAMAS PARA CONTROLAR LA MAQUINA.
