Abstract

SE EXPONEN TECNICAS DE MECANIZADO ELECTROQUIMICAS (ECM) QUE UTILIZAN SUPERVISION PARAMETRICA EN TIEMPO REAL, ALARMAS Y CONTROL DE REALIMENTACION, PARA EL MECANIZADO MEJORADO DE UNA PIEZA. EL DISPOSITIVO ECM UTILIZA UNO O MAS CATODOS, UN ELECTROLITO Y UNA PIEZA CARGADA POSITIVAMENTE PARA OBTENER ACCION ELECTROLITICA. VARIAS VARIABLES DE CONTROL, COMO EL RANGO DE ALIMENTACION DEL CATODO, EL RANGO DE FLUJO DEL ELECTROLITO Y LA TENSION, SE COMPENSAN EN RESPUESTA A PARAMETROS MEDIDOS EN EL SISTEMA. LOS SIGUIENTES PARAMETROS PREFERENTEMENTE SE SUPERVISAN PARA AJUSTAR LAS VARIABLES DE CONTROL: LOS PARAMETROS ACCIONADORES DEL RANGO DE ALIMENTACION Y PROFUNDIDAD DEL CATODO; LOS PARAMETROS DE LA BOMBA DEL RANGO DE FLUJO Y PRESION; Y LOS COMPONENTES ELECTRICOS DE TENSION Y CORRIENTE. EL RANGO DE FLUJO EN CADA UNO DE LOS CATODOS, O UN NUMERO DE REYNOLDS CORRESPONDIENTE, SE UTILIZA PREFERENTEMENTE PARA PROPORCIONAR UNA ALARMA AL OPERADOR SI SE DETECTASE UN CAMBIO ESTADISTICAMENTE SIGNIFICATIVO EN EL FLUJO. EL GRADIENTE DE RESISTENCIA DINAMICA DEL FLUIDO A TRAVES DE UNO O MAS DE LOS HUECOS QUE SE MECANIZAN, SE UTILIZA PARA APROXIMARSE EN TIEMPO REAL A LA FORMA DESEADA DE LA PIEZA A MECANIZAR. LA RESISTENCIA ELECTRICA DINAMICA PUEDE UTILIZARSE PARA MEJORAR LA APROXIMACION A LA FORMA. LOS VALORES APROXIMADOS DE FORMA SE UTILIZAN PARA PROPORCIONAR CONTROL DE RETROALIMENTACION DE UNA O MAS DE LAS VARIABLES DE CONTROL, PARA OBTENER RESULTADOS MEJORADOS. LA RESISTENCIA DINAMICA DEL FLUIDO, ES LA DIFERENCIA ENTRE LA RESISTENCIA TOTAL MEDIDA DEL FLUIDO Y LA RESISTENCIA ESTATICA DEL FLUIDO, SEGUN SE OBTIENE DURANTE UN PROCEDIMIENTO DE CALIBRACION.
