PROCESSING MACHINE, CONTROL DEVICE FOR PROCESSING MACHINE, AND CONTROL METHOD FOR PROCESSING MACHINE

WIPO Patent Application WO/2023/149507

A1

This processing machine comprises: a tool for machining a workpiece; and a depth camera which is installed such that the workpiece lies within an image capturing range thereof, and which captures an image of the depth of a subject. A position measuring unit calculates a three-dimensional position of a surface of the workpiece on the basis of the depth image captured by the depth camera. A positioning unit calculates a three-dimensional position of a target shape of the workpiece when the workpiece and the target shape are superimposed, on the basis of three-dimensional data representing the target shape and the three-dimensional position of the workpiece. A depth-of-cut determining unit determines a depth of cut at each of a plurality of points on the surface of the workpiece on the basis of a difference, in a sight line direction, between the three-dimensional position of the surface of the workpiece when the workpiece is viewed from a predetermined viewpoint, and the three-dimensional position of the surface of the target shape. The tool control unit causes the tool to move on the basis of the determined depth of cut.
