Abstract
In a dimple processing method for forming dimples on a curved surface of a workpiece, a cutting tool having a cutting edge on a rod-shaped body is rotated about a central axis of the cutting tool. The workpiece is rotated about a first axis. The cutting tool or the workpiece moves on a virtual plane through which the first axis passes or on a plane parallel to the virtual plane. The cutting tool or the workpiece moves such that the tip end of the cutting tool follows the curved surface of the workpiece. The cutting edge forms one or more dimple on the curved surface each time the cutting tool rotates.

A dimple processing method for forming a plurality of dimples on a curved surface of a werkpiece, the method comprising:
- rotating a cutting tool having a cutting edge on a rod-shaped body about a central axis of the rod-shaped body;
- rotating the workpiece about a first axis;
- and
- moving the cutting tool or the workpiece along a virtual plane through which the first axis passes or along a plane oriented parallel to the virtual plane such that a tip end of the cutting tool follows the curved surface of the workpiece to allow the cutting edge to form a dimple on the curved surface each time the cutting tool rotates about the central
A dimple processing method for forming a plurality of dimples on a curved surface of a workpece, the method comprising:
- rotating a cutting tool having a cutting edge on a rod-shaped body about a central axis of the rod-shaped body;
- and
- moving the cutting tool or the workpiece in three oriented orthogonal to each other while not rotating the workpiece such that a tip end of the cutting tool follows the curved surface of the workpiece to allow the cutting edge to form a dimple on the curved surface each time the cutting tool rotates about the central axis.
A dimple processing method for forming a plurality of dimples on a curved surface of a workpiece, the method comprising:
- rotating the workpiece about a first axis passing through a spherical center of the workpiece, wherein the curved surface of the workpiece has a partial spherical shape;
- rotating the workpiece about a second axis oriented orthogonal to the first axis;
- and
- rotating a cutting tool having a cutting edge on a rod-shaped body about a central axis of the rod-shaped body such that a tip end of the cutting tool moves along a part of the spherical shape of the workpiece to allow the cutting edge of the cutting tool to form dimples on the curved surface each time the cutting tool rotates about the central axis of the rod-shaped body.
