Abstract
Methods of forging a golf club head is disclosed. Exemplary embodiment may include providing a raw forging blank, hot pre-forging said raw forging blank to create a golf club head without scorelines, cold pre-forging said golf club head to create a rough scoreline pattern, polishing a face of said golf club head to remove an excess material after said cold pre-forging step, and final forging said golf club head to create a final scoreline pattern.
Claims
exact text as granted — not AI-modifiedWhat is claimed is:
1 . A method of forging a golf club head comprising:
providing a raw forging blank, hot pre-forging said raw forging blank to create a golf club head without scorelines, cold pre-forging said golf club head to create a rough scoreline pattern, polishing a face of said golf club head to remove an excess material after said cold pre-forging step, and final forging said golf club head to create a final scoreline pattern, wherein an at least one scoreline of said final scoreline pattern further comprises;
a toe terminus profile,
a heel terminus profile, and
a face centerline, defined as a center point between a toe most portion of said at least one scoreline and a heel most point of said at least one scoreline, and
wherein said toe terminus profile is different from said heel terminus profile.
2 . The method of claim 1 , wherein said at least one scoreline has Heel to Toe Terminus Slope Ratio of greater than about 6, said Heel to Toe Terminus Slope Ratio defined as;
Heel

Toe
Termius
Slope
Ratio
=

3 . The method of claim 2 , wherein said Heel to Toe Terminus Slope Ratio is greater than about 8.75.
4 . The method of claim 2 , wherein said Heel to Toe Terminus Slope Ratio is greater than about 13.
5 . The method of claim 1 , wherein said toe terminus profile has a slope of less than about 0.25.
6 . The method of claim 1 , wherein said toe terminus profile has a slope of less than about 0.20.
7 . The method of claim 1 , wherein said toe terminus profile has a slope of less than about 0.15.
8 . The method of claim 1 , wherein said heel terminus profile has a slope of greater than about 1.5.
9 . The method of claim 1 , wherein said heel terminus profile has a slope of greater than about 1.75.
10 . The method of claim 1 , wherein said heel terminus profile has a slope of greater than about 2.0.
11 . The method of claim 1 , wherein said at least one scoreline is asymmetrical about said face centerline.
12 . The method of claim 1 , wherein said toe terminus profile is chamfered.
13 . The method of claim 1 , wherein said heel terminus profile is chamfered.
14 . A method of forging a golf club head comprising:
providing a raw forging blank, hot pre-forging said raw forging blank to create a golf club head without scorelines, cold pre-forging said golf club head to create a rough scoreline pattern, polishing a face of said golf club head to remove an excess material after said cold pre-forging step, and final forging said golf club head to create a final scoreline pattern after said polishing step, wherein an at least one scoreline of said final scoreline pattern further comprises;
a toe terminus profile,
a heel terminus profile, and
a face centerline, defined as a center point between a toe most portion of said at least one scoreline and a heel most point of said at least one scoreline, and
wherein said at least one scoreline is asymmetrical about said face centerline.
15 . The method of claim 14 , wherein said at least one scoreline has Heel to Toe Terminus Slope Ratio of greater than about 6, said Heel to Toe Terminus Slope Ratio defined as;
Heel

16 . The method of claim 15 , wherein said Heel to Toe Terminus Slope Ratio is greater than about 13.
17 . A method of forging a golf club head comprising:
providing a raw forging blank, hot pre-forging said raw forging blank to create a golf club head without scorelines, cold pre-forging said golf club head to create a rough scoreline pattern, polishing a face of said golf club head to remove an excess material after said cold pre-forging step, and final forging said golf club head to create a precise final scoreline pattern after said polishing step without any secondary machining, wherein precise final scoreline pattern comprises a precise final scoreline shape, a precise final scoreline profile, and a precise final scoreline geometry, wherein an at least one precise final scoreline of said precise final scoreline pattern further comprises;
a precise final toe terminus profile,
a precise final heel terminus profile, and
a precise final face centerline, defined as a center point between a toe most portion of said at least one precise final scoreline and a heel most point of said at least one precise final scoreline.
18 . The method of claim 17 , wherein said at least one precise final scoreline has Heel to Toe Terminus Slope Ratio of greater than about 6, said Heel to Toe Terminus Slope Ratio defined as;
Heel

19 . The method of claim 17 , wherein said Heel to Toe Terminus Slope Ratio is greater than about 13.
20 . The method of claim 17 , wherein said at least one precise final scoreline is asymmetrical about said precise final face centerline.Join the waitlist — get patent alerts
