Machine learning to design driver and iron faces

Callaway said machine learning cut some club design tasks from four to five weeks to a couple of days

WorkingCompany's own claim

Problem

Club development at Callaway typically took 12 to 16 months and produced only three or four prototypes. Engineers set face designs by hand, and testing each idea was slow.

Approach

Callaway fed design parameters and 20 years of golf shot data into machine learning run on a supercomputer of about 1,000 cores. The software worked out the face design on its own. For the Flash driver it produced a thickness pattern with ripples and ridges that engineers could not fully explain but that gave more ball speed.

Results

a couple of daystime for tasks that used to take four to five weeks, as stated by Callaway's head of R&DCompany's own claim[1]

Takeaway

Machine learning let engineers test far more designs in the same time. The speed claim came from Callaway's R&D chief in a 2020 interview.
