Abstract

METODO PARA REDUCIR EL DESGASTE DEL ELECTRODO EN MAQUINAS DE MECANIZADO POR ELECTROEROSION. CONSISTE EN DOTAR AL CIRCUITO DE VARIAS ETAPAS DE POTENCIA; LA TENSION DE LA PRIMERA PUEDE SER SUPERIOR, FACILITANDO LA IONIZACION DEL CANAL Y DISMINUYENDO EL RETARDO DE IONIZACION. UN CIRCUITO DETECTA LA IONIZACION Y PONE EN MARCHA UNOS CONTADORES PROGRAMABLES QUE CUENTAN IMPULSOS PROCEDENTES DE LA BASE DE TIEMPOS, CUYA FRECUENCIA ES SUPERIOR A LA DE LOS IMPULSOS DE TRABAJO; TRANSCURRIDA LA CUENTA PRESELECCIONADA, EL CIRCUITO EMITE UNA SEÑAL DE CONDUCCION A LA ETAPA DE POTENCIA SIGUIENTE, QUE SUMINISTRA UN IMPULSO DE CORRIENTE MAS FUERTE, CON CIERTO RETARD CON RESPECTO AL PRIMERO Y ASI SUCESIVAMENTE. CONSIGUIENDOSE QUE LA CORRIENTE DE TRABAJO SE ESTABLEZCA DE FORMA ESCALONADA, PUDIENDO REALIZARSE EN UNO O MAS SALTOS DE MANERA QUE LAS CORRIENTES SELECCIONADAS VAYAN EN AUMENTO PROGRESIVO, VARIANDO A VOLUNTAD LAFORMA DEL FLANCO DE SUBIDA DEL IMPULSO DE CORRIENTE. ESTE METODO DISMINUYE EL DESGASTE DEL ELECTRODO COMO MINIMO EN UN 50%.
