1. 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. |
