Abstract

EL INVENTO SE REFIERE A UN PROCEDIMIENTO Y UN MECANISMO PARA EL CONTROL DE UNOS PROCESOS DE EROSION POR CHISPAS EN UNA MAQUINA DE EROSION POR CHISPAS. MIDEN LA TENSION DE IMPULSOS EN LAS GRIESTAS Y GENERAN UNA ORDEN DE MANDO SEGUN LA DESVIACION DE LA TENSION REAL RESPECTO DE LA TENSION TEORICA, LOS DATOS DE PROCESO MODIFICAN LA EROSION POR CHISPAS DE LA MAQUINA. LA TENSION DE IMPULSO DE DIFERENTES UNIDADES DE RETARDO DE ENCENDIDO SE COORDINA MEDIANTE GRUPOS DE IMPULSOS PRECALENTADOS DE LA ZONA DE ENCENDIDO. SE CUENTA EN CADA GRUPO DE IMPULSOS PRESENTADOS Y SEGUN EL SOBREEXCESO INDICADO, EN UN PROCESO DE DEGENERACION DE GRUPOS DE IMPULSOS RESPECTO A UNA PORCION LIMITE PRECALCULADA DE IMPULSOS CORRELATIVOS, SE GENERA UNA ORDEN DE MANDO. LOS DATOS DEL PROCESO DE LA MAQUINA DE EROSION POR CHISPAS, CAMBIA DE SENTIDO UNA NORMALIZACION DE LOS PROCESOS
