Title (EN) METHOD FOR DETERMINING A DIMENSION BETWEEN THE BACK AND THE CUTTING EDGE OF A VIBRATING BLADE MOUNTED ON A CUTTING TOOL
(FR) PROCÉDÉ DE DÉTERMINATION D'UNE DIMENSION ENTRE LE DOS ET LE FIL TRANCHANT D'UNE LAME VIBRANTE MONTÉE SUR UN OUTIL DE COUPE
Abstract:
(EN) The invention relates to a method for determining a dimension between the back and the cutting edge (4a) of a vibrating blade (4) mounted on the cutting head, consisting in successively acquiring a digital image of the blade mounted on the cutting tool in such a way that a line (L1) corresponding to a cutting edge (4b) of the blade and a line (L2) corresponding to a back (4c) of the blade are visible in the image, determining, in the digital image along a straight line (L3) perpendicular to the line corresponding to the cutting edge of the blade the number of pixels contained between the line corresponding to the cutting edge of the blade and the line corresponding to the back of the blade, and calculating a filtered dimension (d) between the back and the cutting edge of the blade from the number of pixels contained between the line corresponding to the cutting edge of the blade and the line corresponding to the back of the blade.
(FR) L'invention concerne un procédé de détermination d'une dimension entre le dos et le fil tranchant (4a) d'une lame vibrante (4) montée sur une tête de coupe, consistant successivement à acquérir une image numérique de la lame montée sur l'outil de coupe de façon à ce qu'une ligne (L1) correspondant à un tranchant (4b) de la lame et une ligne (L2) correspondant à un dos (4c) de la lame soient visibles sur l'image, déterminer sur l'image numérique le long d'une droite (L3) perpendiculaire à la ligne correspondant au tranchant de la lame le nombre de pixels compris entre la ligne correspondant au tranchant de la lame et la ligne correspondant au dos de la lame, et calculer une dimension filtrée (d) entre le dos et le fil tranchant de la lame à partir du nombre de pixels compris entre la ligne correspondant au tranchant de la lame et la ligne correspondant au dos de la lame.
