Abstract

LA INVENCION SE REFIERE A UN PROCEDIMIENTO DE RECTIFICADO CONTROLADO CNC PARA EL BORDE PERIMETRICO Y LA FACETA SUPERIOR DE UN CRISTAL DE LENTES. SE DETERMINA LA LONGITUD DEL VERTICE DE RANURA DE RECEPCION DE FACETA DE UN MONTAJE DE LENTES DE GAFAS SELECCIONADO, SIENDO DETERMINADA LA LONGITUD DE LA CIRCUNFERENCIA DEL VERTICE DE LA FACETA SUPERIOR EN EL AREA DEL BORDE CIRCUNFERENCIAL DE LA LENTE DE GAFAS A SER MONTADA EN LAS GAFAS CORRESPONDIENTES Y TRABAJANDO DE ACUERDO CON LOS DATOS OPTOMETRICOS DEL PERSONAL, QUE CORRESPONDEN AL UTILIZADOR DE LA LENTE, SIENDO COMPARADA LA LONGITUD DE LA RANURA DE RECEPCION DE FACETA SUPERIOR Y SI SE REQUIERE CON LA POSICION Y/O EL DESARROLLO DE LA FACETA SUPERIOR SOBRE EL BORDE CIRCUNFERENCIAL DE LAS LENTES DE GAFAS, SIENDO MODIFICADAS, DE TAL MODO QUE LA DESVIACION ENTRE LA LONGITUD DE LA RANURA DE FACETAS Y LA LONGITUD DE LA FACETA SUPERIOR DEBE ENCONTRARSE DENTRO DE LOS LIMITES ADMISIBLES PREDETERMINADOS. LA FACETA SUPERIOR SE APLICA A PROCESOS DE ACABADO DE ACUERDO CON LOS VALORES RESULTANTES A PARTIR DE LA COMPARACION, MODIFICANDOSE SI ES NECESARIO.
