Abstract

UNA SONDA DE CAPACITANCIA (26) SE UTILIZA EN UNA MAQUINA DE MEDICION DE COORDENADAS O EN UNA HERRAMIENTA PARA DETERMINAR LA DISTANCIA ENTRE LA SONDA Y UNA SUPERFICIE DE UNA PIEZA DE TRABAJO (30). PARA CALIBRARLA, SE ACERCA Y SE SEPARA DE LA SUPERFICIE, Y SE TOMA UNA SERIE DE LECTURAS DE LA CAPACITANCIA CONTRA LA DISTANCIA MOVIDA. ESTAS PUEDEN UTILIZARSE ENTONCES PARA DETERMINAR LOS VALORES DE CALIBRACION, POR EJEMPLO, UTILIZANDO UN ALGORITMO DE "MEJOR AJUSTE" CON UNA ECUACION RELATIVA A LA CAPACITANCIA A LA DISTANCIA MOVIDA. PUEDEN OBTENERSE VALORES DE CALIBRACION DIFERENTES PARA PUNTOS DIFERENTES DE LA SUPERFICIE, PARA TENER EN CUENTA LA FORMA LOCAL DIFERENTE DE CADA PUNTO.
