Abstract
The present invention is a golf ball which comprises dimples having a cross-sectional shape defined by the superposition of a weighted profile and one or more additional profiles, and a method of making such dimples. The dimples preferably have a circular boundary and maintain an axis coincident with the center of the circular boundary.
Claims11
A golf ball having a plurality of recessed dimples on the surface thereof, wherein at least a portion of the recessed dimples have a non-spherical cross-sectional profile defined by a function ƒ(x) resulting from the sum of a weighted function and one or more additional functions g(x), wherein the weighted function is the multiplication of a single continuous, differentiable function b(x) and at least one weighting function w(x) selected from the group consisting of polynomial, exponential, and trigonometric functions, such that the function defining the cross-sectional profile is expressed as
- ƒ(x)=(b(x)*w(x))+g(x).
