Abstract
Golf club heads with patterned face plates described herein. Other examples, embodiments and related methods are also disclosed herein.
Claims19
A method for providing a golf club head, the method 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 a single elliptical orbit to define a contoured surface at the back side such that no further passes are required to define the contoured surface, the contoured surface including a central region having a first elliptical outer edge surrounded by a transition region extended from the central region to a peripheral region, the transition region having a second elliptical outer edge and a thickness decreasing in a non-linear transition from the first elliptical outer edge to the second elliptical outer edge, the thickness measured from the strike side to the back side;
- wherein the first elliptical outer edge has a first aspect ratio, a first major axis, and a first minor axis;
- wherein the second elliptical outer edge has a second aspect ratio, a second major axis, and a second minor axis;
- and
- wherein the second major axis is equal to the first major axis plus a predefined distance, the second minor axis is equal to the first minor axis plus the predefined distance, and the second aspect ratio is less than the first aspect ratio.

A method for providing a golf club head, the method comprising:
- providing a shell having an opening;
- and
- providing a face plate configured to be attached to the opening to form a hollow body, the face plate having a strike and a back side;
- and
- milling the face plate in a single elliptical orbit to define a frustum-like surface of revolution at the back side such that no further passes are required to define the frustum-like surface of revolution, the frustum-like surface of revolution including a first region having a first elliptical outer edge, a second region having a second elliptical outer edge, and a transition region between the first region and the second region, the transition region having a curved surface extending from the first elliptical outer edge to the second elliptical outer edge and a thickness decreasing in a non-linear transition from the first elliptical outer edge to the second elliptical outer edge, the thickness measured from the strike side to the back side;
- wherein the first elliptical outer edge has a first aspect ratio, a first major axis, and a first minor axis;
- wherein the second elliptical outer edge has a second aspect ratio, a second major axis and a second minor axis;
- and
- wherein the second major axis is equal to the first major axis plus a predefined distance, the second minor axis is equal to the first minor axis plus the predefined distance, and the second aspect ratio is less than the first aspect ratio.
