Document Type and Number:
WIPO Patent Application WO/2020/100536
Kind Code:
A1
Abstract:
The purpose of the present invention is to eliminate the formation of a shape that induces reduction of fatigue strength, without forming a step part, in a shape portion formed by machining. This processing apparatus (1) comprises: end mills (2, 3) having bottom blades formed in a curved convex shape, and arcuately formed radial blades provided in corner areas; a drive section (4) for driving the end mills (2, 3); and a control unit (5) for controlling the drive unit (4). The control unit (5) is provided with: a planar-shape-formation unit (6) that controls the drive unit (4) so as to form, in a workpiece, only a planar-shape portion adjacent to a fillet shape portion in such a manner that a portion of the shape to be processed corresponding to the fillet shape portion is left unprocessed; and a fillet formation unit (7) that controls the drive unit (4) so as to form the fillet shape portion in the workpiece in a single pass using the radial blades.
