Title (EN) METHOD FOR SCANNING THE SURFACE OF A WORKPIECE
(FR) PROCÉDÉ DE BALAYAGE DE LA SURFACE D'UNE PIÈCE À USINER
Abstract: front page image
(EN)A method for measuring a surface profile using a surface sensing device mounted on an articulating probe head in which the probe head is moved along a nominal path relative to the surface profile, an at least approximation of the surface normal of the surface profile, the surface profile is sensed with the surface sensing device and the distance or force of the surface sensing device relative to the surface profile substantially in the direction of the surface normal. The surface normal may be determined by approximating at least one section to a curved profile which can be mathematically parameterised.
(FR)L'invention concerne un procédé permettant de mesurer le profil d'une surface au moyen d'un dispositif de détection de surface monté sur une tête de sonde articulée, celle-ci étant déplacée le long d'un chemin nominal par rapport au profil de la surface, et de déterminer au moins une approximation de la normale de surface du profil de la surface, celui-ci étant détecté au moyen du dispositif de détection de surface et la distance ou la force de celui-ci par rapport au profil de la surface étant sensiblement dans la direction de la normale de surface. Celle-ci peut être déterminée par approximation d'au moins une section à un profil incurvé pouvant être paramétrisé de manière mathématique.
