Abstract

Procédé de mesure de la configuration de contour d'un article défini par de nombreuses portions de surface cylindriques, comprenant le placement de l'article (1) sur une table tournante (2), l'envoi de rayons lumineux parallèles sur une partie latérale de l'article (1) tout en faisant tourner la table tournante (2), la détection de modifications, en tant que fonction L (O), au moyen d'un organe de réception de lumière (4), en des endroits L auxquels les rayons lumineux parallèles sont interrompus par l'article (1), O représentant un angle de rotation de la table tournante (2), l'entrée de données de L(O) ainsi détectées dans la mémoire d'un ordinateur, le calcul de la valeur L(O) + L(O)+180 degrés), la comparaison de la valeur ainsi calculée avec celle d'une configuration de contour idéale, et la correction des déviations dans une position et un angle de l'article (1), de manière à obtenir une valeur mesurée correcte.
