Title:
DIMPLE MACHINING METHOD
Document Type and Number:
WIPO Patent Application WO/2021/049260
Kind Code:
A1
Abstract:
In a dimple machining method for forming dimples in a curved surface (41) of an object (40) to be machined, a cutting tool 1 having a cutting edge (5a) on a rod-like body (2) is rotated about an axis (2a). The object (40) to be machined is rotated about a first axis (20a). The cutting tool (1) or the object (40) to be machined is moved over a virtual plane through which the first axis (20a) passes and that is perpendicular to the Y axis or over a plane parallel to the virtual plane such that a distal end (3) of the cutting tool (1) moves over the curved surface (41) of the object (40) to be machined. The cutting edge (5a) forms a dimple in the curved surface (41) each time the cutting tool 1 is rotated.
