Abstract
Embodiments of grooves of golf club heads and methods to manufacture grooves of golf club heads are generally described herein. Other embodiments may be described and claimed.
Claims22
A golf club head comprising:
- body portion having a body toe portion, a body heel portion, a body top rail portion and a body sole portion;
- a club face on the body portion between the body toe portion and the body heel portion and between the body top rail portion and the body sole portion;
- and
- a plurality of grooves disposed on the club face, each groove comprising a groove heel portion proximate to the body heel portion and extending toward the body toe portion;
- a groove toe portion, proximate to the body toe portion and extending toward the body heel portion, and a groove center portion extending between the groove heel portion and the groove toe portion and including a deepest part of the groove;
- wherein a depth of each groove increases from, the groove, heel portion to the deepest part of the groove;
- wherein a depth of each groove increases from the groove toe portion to the deepest part of the groove;
- wherein depths of the grooves increase in a direction from the body top rail, portion to a generally central region on the club face between the body toe portion, the body heel portion, the body top rail portion and the body sole portion;
- and
- wherein depths of the grooves increase in a direction from the body sole portion to the generally central region.

A method of manufacturing a golf club head comprising:
- forming a body portion defined by a body toe portion , a body heel portion a body top rail portion and a body sole portion;
- forming a club face, the club face located on the body portion between the body toe portion and the body heel portion and between the body top rail portion. and the body sole portion;
- forming a plurality of grooves on the club face, each groove comprising a groove heel portion proximate to the body heel portion and extending toward the body toe portion;, a groove toe portion proximate to the body toe portion and extending toward the body heel portion, and a groove center portion extending between the groove heel portion and the groove toe portion and including a deepest part of the groove;
- wherein forming the plurality of grooves comprises:
- forming each groove such that a depth of each groove increases from the groove heel portion to the deepest part of the groove;
- forming each groove such that a depth of each groove increases from, the groove toe portion to the deepest part of the groove;
- forming the plurality of grooves such that depths of the grooves increase in a direction from the body top rail portion to a generally central region on the club face between the body toe portion, the body heel portion, the body top rail portion and the body sole portion;
- and
- forming the plurality of grooves such that depths of the grooves increase in a direction from the body sole portion to the central region.

- a body portion having a body toe portion, a body heel portion, a body top rail portion and a body sole portion;
- a club face on the body portion between the body toe portion and the body heel portion and between the body top rail portion and the body sole portion;
- and
- a plurality of grooves disposed on the club face, each groove comprising a groove heel portion proximate to the body heel portion and extending toward the body toe portion;
- a groove toe portion proximate to the body toe portion and extending toward the body heel portion, and a groove center portion extending between the groove heel portion and the groove toe portion and including a deepest part of the groove;
- wherein a depth of each groove increases from the groove heel portion to the deepest part of the groove:
- wherein a depth of each groove increases from the groove toe portion to the deepest part of the groove;
- wherein depths of the grooves, increase in a direction from the body top rail portion to a generally central region on the club face between the body toe portion, the body heel portion, the body top rail portion and the body sole portion;
- wherein depths of the grooves increase in a direction from the body sole portion to the central region;
- wherein a change in the depth of each groove between the groove center portion and the groove heel portion is greater than a change in the depth of the groove along the groove center portion.;
- wherein a change in the depth of each groove between the groove center portion and the groove, heel portion is greater than a change in the depth of the groove along the groove heel portion;
- wherein a change in the depth of each groove between the groove center portion and the groove toe portion is greater than a change in the depth of the groove, along the groove center portion;
- and
- wherein a change in the depth of each groove between the groove center portion and the groove toe portion is greater than a change in the depth of the groove along the groove toe portion.
