Developing the Perfect Golf Ball
Golfers around the world realize that
it’s important to find that perfect ball that suits their game - not
too soft, not too hard, enough spin but not too much....
And choosing that perfect golf ball
is no easy task. Believe it or not, the United States Golf
Association includes close to 1,900 balls on its "conforming" list.
There are two-piece balls, three-piece balls, balata and Surlyn
balls, wound balls, liquid-center balls, titanium-center balls,
"senior" balls, "ladies" balls, balls that offer "extra distance" or
"extra spin" and thanks to R&D in the golf ball industry, many
hybrid balls that combine these characteristics.
One golf ball manufacturer, long
regarded as the most prestigious brand name in the $1
billion-per-year golf-ball industry, offers an array of golf ball
types to suit the games of every type of golfer. Indeed, the
manufacturer makes so many different types of balls and so many
compressions, it is confusing even to professional golfers. So, for
the average hit and hope golfer like me, is there really a ball out
there that will improve my game? And what’s new on the radical golf
ball engineering frontier to help my golf game?
Research and Development
The manufacturer’s Research and
Development Department takes on the challenge to continually improve
the quality and composition of their golf balls and to expand their
product lines. A scientist in the R&D Department says one of the
critical elements of a golf ball is the core composition. The core
is the golf ball’s source of energy. Differences in core
construction affect spin rate (control), initial velocity (distance)
and compression (feel).
The typical core construction,
either wound or solid, offer significant differences in control and
feel. Wound balls have three parts: center, winding and cover. Wound
balls offer more spin and control but typically less distance. Solid
balls are comprised of two parts, a solid core and cover. Solid, or
two-piece balls, offer more distance but less spin and control. In
general, the core is generally a compound of natural and synthetic
rubbers (polymers).
The R&D Department conducts core
compression experiments to continually improve the interior design
of their golf balls. The Department uses rheometers, an instrument
for measuring the flow of viscous liquids, made by Monsanto, to
measure different heating cycles of the polymers that comprise a
golf ball’s center. Measuring different heating cycles simulates
part of the actual process of developing the ball’s core. By
simulating the process with the rheometer, the Department can
perfect the heating and compression process to improve the golf
ball’s core, and hence, overall control and feel of the ball.
The WinWedge Solution
Monsanto, the manufacturer of the
rheometer, offers its own SPC software to analyze the output of the
device. However, the Department had a need to overlay curves for
different heating cycles which the custom SPC package would not
allow. They discovered that by using the SoftwareWedge for Windows
Professional version (WinWedge Pro), by TALtech of Philadelphia,
Pennsylvania (800-722-6004, www.taltech.com), to interface the
rheometer to their personal computer running Windows 95, they could
overlay the heating curves and analyze their results in Microsoft
Excel. The R&D scientists preferred to use Excel since they are
familiar with it, and Excel is easy to use and a powerful
statistical analysis program.
At present the rheometer is
connected via a serial cable to a PC running Microsoft Excel and
WinWedge. WinWedge parses and filters the data from the rheometer
and directs it to Excel. The data is then graphed in real time in
Excel. The resulting graphs simulate the heating cycles.
In Search of the Perfect Ball
So with all this on-going golf ball
technology, how do you select the right golf ball for your game? Try
surfing the Internet. You will find web sites that take you through
a series of simple questions, such as typical drive distance,
preference for control or distance, rating of golf ball
characteristics, etc. Or perhaps seek assistance from your pro or
salesclerk.
So partake when the nice weather is
nice and hit the links. And don’t forget a sleeve of your favorite
balls! Or if you play like this author, bring a whole box!
