Abstract

Golf club heads with patterned face plates described herein. Other examples, embodiments and related methods are also disclosed herein.

Claims

1. A method for manufacturing a golf club head comprising:

providing a face plate material for a face plate having a strike side and a back side; and

milling the face plate material in an elliptical pattern to concurrently form, in a single elliptical orbit;

a central region comprising a first elliptical outer edge;

a transition region extending from the first elliptical outer edge to a second elliptical outer edge; and

a peripheral region bounding the transition region and extending from the second elliptical outer edge out to a face plate edge of the face plate;

wherein;

the elliptical pattern and the first, second, and face plate edges are non-circular;

the transition region comprises a substantially constant width throughout the transition region and between the first and second elliptical outer edges; and

from the strike side to the back side of the face plate material;

an entirety of the central region within the first elliptical outer edge is thicker than the transition region past the first elliptical outer edge and thicker than the peripheral region past the second elliptical outer edge.

2. The method of claim 1, wherein:

the elliptical pattern, and the first, and second elliptical outer edges, have a contour different than a contour of the face plate edge.

3. The method of claim 1, wherein:

milling the face plate further comprises;

milling the face plate material in the single elliptical orbit such that no further passes are required to complete the milling of the face plate material to define the central region, the transition region, and the peripheral region.

4. The method of claim 1, wherein:

milling the face plate material comprises;

using a form cutter to mill the face plate material, the form cutter comprising first and second cutting surfaces different from each other;

wherein;

the second cutting surface is substantially flat and perpendicular to a rotating axis of the form cutter;

the transition region is formed by the first cutting surface during the single elliptical orbit;

the second cutting surface extends from the second edge to the face plate edge such that the peripheral region is formed by the second cutting surface during the single elliptical orbit; and

the form cutter does not contact the central region, except for the first elliptical outer edge, during the single elliptical orbit.

5. The method of claim 4, wherein:

each point along the second elliptical outer edge is displaced outward from the first elliptical outer edge by a first predetermined distance determined by the first cutting surface.

6. The method of claim 1, wherein:

the transition region comprises a non-linear transition from the first elliptical outer edge to the second elliptical outer edge; and

an entirety of the non-linear transition of the transition region is convex relative to the strike side.

7. The method of claim 1, wherein:

the transition region comprises a non-linear transition from the first elliptical outer edge to the second elliptical outer edge; and

an entirety of the non-linear transition of the transition region is concave relative to the strike side.

8. The method of claim 1, wherein:

a centerpoint of the central region comprises a thickness substantially similar to a blank face plate thickness of the face plate material.
