Abstract

Appareil d'usinage de matériaux au moyen d'un faisceau de porteurs de charges traversant un champ magnétique perturbateur. Un dispositif de mesure de champ magnétique 10, 30 réagissant au champ perturbateur est disposé latéralement au trajet du faisceau, qui réagit à au moins une composante, perpendiculaire audit trajet, du champ magnétique perturbateur, un signal correspondant à l'intensité et à la direction de la composante du champ perturbateur, émis par le dispositif de mesure de champ est envoyé à un dispositif de compensation, pour compenser la composante de champ magnétique mesurée. Application, aux appareils d'usinage par faisceau électronique
