Document Type and Number:
Japanese Patent JP5543316
Kind Code:
B2
Abstract:
A method for manufacturing a golf ball includes the step of designing plural dimples on a surface of the golf ball so as to satisfy the following parameters. A total number N of the dimples is approximately 400 or less; a surface roughness Rda of the golf ball is approximately 0.085 mm or less; and a value obtained by dividing an average convex part surface area Srt in the first cross-section and the second cross-section by an average concave part cross-section Sru in the first cross-section and the second cross-section is approximately 0.9 or less. The golf ball surface roughness Rda is the average value of a first golf ball cross-section surface roughness Rp, a second golf ball cross-section surface roughness Rm, and a third golf ball cross-section surface roughness Rs. The average convex part surface area Srt is the average value of a first convex part surface area Art that, in the first cross-section, is surrounded by the reference spherical surface and the golf ball surface that is higher than the reference spherical surface and a second convex part surface area Art that, in the second cross-section, is surrounded by the reference spherical surface and the golf ball surface that is higher than the reference spherical surface.
