Abstract

Ce dispositif de traçage (1) forme une ligne de traçage courbe fermée (4) sur la surface (3) d'une plaque de verre (2) au moyen d'un organe de commande numérique. Le dispositif de traçage (1) forme la ligne de traçage courbe fermée (4) sur la surface (3) de la plaque de verre (2) par déplacement d'une roulette de découpe (5) et de la plaque de verre (2) dans un système de coordonnées planes X-Y pour produire une ligne de contour tout en procédant à une commande angulaire de la roulette de découpe (5) autour d'une ligne axiale (37) qui est orthogonale au système de coordonnées planes de manière à orienter la surface de la lame (9) de la roulette de découpe (5) afin qu'elle soit toujours dans une direction perpendiculaire (8) à la ligne de contour (10). Simultanément, pendant le mouvement de formation de la ligne de traçage (4), le dispositif de traçage (1) fait passer la roulette de découpe (5) dans la direction perpendiculaire (8) entre une orientation verticale (11) qui est orthogonale à la surface (3) de la plaque de verre (2), et une orientation (12) qui est inclinée par rapport à la surface (3) de la plaque de verre (2).
