Abstract: A lens edging machine is numerically controlled by a computer to determine the rotation and displacement of a lens workpiece (16) with respect to an edging tool (10) in accordance with a lens shape stored in memory (60). The system continuously translates the lens workpiece (16) axially across the surface of the wheel (12, 14) to uniformly distribute wear across the wheel surface, reducing the need to dress the edging tool (10). The system compares the lens size with predetermined dimensions and compensates for any difference by automatically adjusting the lens trajectory during the edging of subsequent lens workpieces, permitting the edging tool to wear down without appreciable errors in lens size. The system controls the edging tool speed, the lens rotation rate, the lens axial feed velocity and the grinding force between the lens workpiece and the wheel at each discrete point during the entire lens edging operation to optimize production while preventing overheating of the lens workpiece. The optimum values for these parameters are empirically determined in a preparatory programmed trial and error learning process of the invention. <IMAGE>

Abstract: Un rouleau de formage pour laminoirs de tuyaux sert à former des tuyaux, tels que des tuyaux à soudure continue, par formage continu. Un procédé et un appareil permettent de former des bandes de matériau avec ce rouleau de formage. Le rouleau de formage présente une courbe développante fondée sur un polygone composé d'une pluralité de côtés prédéterminés de sorte que la section transversale de la surface du rouleau ait la forme de surfaces courbes dont les rayons de courbure varient constamment selon un rapport mutuel constant. Les surfaces courbes à rayons de courbure divers peuvent être déterminées sur la surface du rouleau selon le diamètre des tuyaux que l'on veut produire. Ainsi, dans un appareil utilisé pour former la partie terminale de la bande de matériau, par exemple, on peut changer la distance entre deux rouleaux de formage selon la largeur de la bande de matériau. De même, on peut ajuster l'orientation des rouleaux de sorte qu'ils butent de manière correcte contre la bande de matériau. La partie terminale de la bande de matériau peut ainsi recevoir la forme voulue, car les rouleaux de formage auront la partie courbe superficielle requise pour former des tuyaux ayant le diamètre voulu. Lorsque ces rouleaux sont utilisés comme rouleaux horizontaux, rouleaux latéraux ou similaires à chaque étape de l'opération de formage, on peut réduire le nombre d'étapes à rouleaux de formage. On peut en outre effectuer des opérations de formage pour produire des tuyaux en acier à diamètres divers, depuis les plus petits jusqu'aux plus grands, et à parois d'épaisseurs diverses, sans avoir à remplacer les rouleaux de formage.
