Abstract
(EN)
A numerical control device (1X) for controlling: a main shaft (60) which constitutes the axis of rotation of a workpiece (70); a drive shaft (61X) which drives, in the X-axis direction, a tool (66A) for performing vibratory cutting on the workpiece (70); and a drive shaft (61Z) which drives the tool (66A) or the workpiece (70) in the Z-axis direction. The numerical control device (1X) comprises: a storage unit (34) which stores a machining program for performing vibratory cutting on the workpiece (70); and a control calculation unit (2X) which, on the basis of a tolerance value that is an error permitted when performing corner machining on the workpiece (70), calculates a specific point through which the tool (66A) passes at the time of the vibratory cutting, and generates a vibration waveform for the tool (66A), said vibration waveform representing the path of movement of the tool (66A) when the tool (66A) passes through the specific point, wherein the control calculation unit (2X) controls the movement and vibration of the tool (66A) in accordance with the machining program and the vibration waveform.

La présente invention porte sur un dispositif de commande numérique (1X) servant à commander : un arbre principal (60) qui constitue l'axe de rotation d'une pièce à usiner (70) ; un arbre d'entraînement (61X) qui entraîne, dans la direction d'axe X, un outil (66A) de façon à effectuer une coupe vibratoire sur la pièce à usiner (70) ; et un arbre d'entraînement (61Z) qui entraîne l'outil (66A) ou la pièce à usiner (70) dans la direction de l'axe Z. Le dispositif de commande numérique (1X) comprend : une unité de mémoire (34) qui stocke un programme d'usinage en vue de la réalisation d'une coupe vibratoire sur la pièce à usiner (70) ; et une unité de calcul de commande (2X) qui calcule, sur la base d'une valeur de tolérance qui est une erreur autorisée lors de la réalisation d'un usinage cornier sur la pièce à usiner (70), un point spécifique par lequel l'outil (66A) passe au moment de la coupe vibratoire, et qui génère une forme d'onde de vibration concernant l'outil (66A), ladite forme d'onde de vibration représentant le trajet de déplacement de l'outil (66A) lorsque ce dernier (66A) passe par le point spécifique, et l'unité de calcul de commande (2X) commandant le déplacement et la vibration de l'outil (66A) conformément au programme d'usinage et à la forme d'onde de vibration.
