Abstract
A method for forming dimples on a workpiece includes providing a rotary cutting tool. The rotary cutting tool includes a cutting edge that protrudes in a leading direction parallel to a longitudinal axis of the tool. The cutting edge extends from a position at the leading end of the rod-shaped main body that is radially offset from the longitudinal axis. The rotary cutting tool is set such that the longitudinal axis of the rotary cutting tool is inclined relative to a line perpendicular to the processing surface of the workpiece. The rotary cutting tool is moved along the processing surface while the rotary cutting tool is rotated about the axis. The processing surface is cut by the cutting edge to form the dimples, which are spaced apart from each other on the processing surface.

A method for forming dimples on a workpiece with a rotary cutting tool, the dimples each having:
- a respective first inclined surface inclined relative to a processing surface of the workpiece, and a respective second inclined surface inclined relative to the processing surface, the method comprising:
- providing a rotary cutting tool including a first cutting edge and a second cutting edge, the first cutting edge and the second cutting edge projecting axially from a leading end face of a rod-shaped main body and being configured to form two sides of a triangle, wherein a plane of the leading end face forms the third side of the triangle, and wherein the first cutting edge and the second cutting edge are radially offset from a longitudinal axis of the rotary cutting tool;
- orienting the rotary cutting tool such that the longitudinal axis of the rotary cutting tool is inclined at an acute angle with respect to a line oriented perpendicular to the processing surface of the workpiece;
- and
