Abstract

UNA MAQUINA PERFILADORA DE LENTES ESTA NUMERICAMENTE CONTROLADA POR UN ORDENADOR PARA DETERMINAR LA ROTACION Y DESPLAZAMIENTO DE UNA PIEZA DE LENTE (16) CON RESPECTO A LA HERRAMIENTA PERFILADORA (10) EN RELACION CON LA FORMA DE LA LENTE ALMACENADA EN LA MEMORIA (60). EL SISTEMA TRASLADA CONTINUAMENTE LA PIEZA (16) DE LENTES AXIALMENTE POR LA SUPERFICIE DE LA RUEDA (12, 14) PARA DISTRIBUIR UNIFORMEMENTE EL DESGASTE DE LA SUPERFICIE DE LA RUEDA, REDUCIENDO LA NECESIDAD DE AFILAR EL FILO DE LA HERRAMIENTA (10). EL SISTEMA COMPARA EL TAMAÑO DE LA LENTE CON LAS DIMENSIONES PREDETERMINADAS Y COMPENSA CUALQUIER DIFERENCIA, AJUSTANDO AUTOMATICAMENTE LA TRAYECTORIA DE LA LENTE DURANTE EL PERFILADO DE PIEZAS DE LENTES POSTERIORES, PERMITIENDO A LA HERRAMIENTA PERFILADORA DESGASTARSE, SIN PRODUCIR ERRORES APRECIABLES EN EL TAMAÑO DE LA LENTE. EL SISTEMA CONTROLA LA VELOCIDAD DE LA HERRAMIENTA PERFILADORA, LA VELOCIDAD DE ROTACION DE LA LENTE, LA VELOCIDAD AXIAL DE ALIMENTACION DE LA LENTE Y LA FUERZADE LIMADO ENTRE LA LENTE Y LA RUEDA EN CADA PUNTO DISCRETO DURANTE TODA LA OPERACION DE PERFILADO DE LA LENTE PARA OPTIMIZAR LA PRODUCCION MIENTRAS SE EVITA EL RECALENTAMIENTO DE LA LENTE. LOS VALORES OPTIMOS PARA ESOS PARAMETROS SON DETERMINADOS EMPIRICAMENTE EN UN PROCESO PROGRAMADO DE APRENDIZAJE DE LA INVENCION POR ENSAYO Y ERROR.
