Personal CAD Project: Tennis Racket
The inspiration for my personal CAD project was my hobby, tennis. So I made an attempt at
modeling my current primary tennis racket, a Slazenger Quad Tour Flex, and a simple Penn tennis
ball in SolidWorks. A photograph of the racket I modeled off from
is pictured right. I believe that this object was right in the realm of
difficulty for me because it tested all that I have learned in
SolidWorks throughout the semester. The different parts of the
racket required different techniques I learned in previous CAD
models. The handle required an extruded base of a strange shape
that I measured to the nearest millimeter. All of the strings in the
frame of the racket were just simple extruded bosses, one for the 16
vertical and one for the 19 horizontal strings. The extra string that
ended up hanging out the frame was cut off by using an extruded
cut around the frame. The frame itself was the most difficult and
tedious part of the model requiring the most measurements to first
draft one side in one plane then mirror the entities to the other side.
This was then extruded back and all of the edges of the racket were
filleted depending on their radii to smoothen out the object. The
tennis ball was a quick two minute addition made by revolving a
curve of certain radius. By requiring these several aspects learned
throughout the lessons in SolidWorks, I believe that this tennis
racket was a perfect object to wrap up CAD for the Engineering
Design course. From this project I have learned that with given time and experience, just about
anything can be remodeled from scratch through CAD and the final results can look amazing.
This was the resulting model of the racket and ball showing also a Slazenger and Penn decal
that were added for texture:
The drawing for this racket does not include all of the dimensions since that would be too
much for a small sheet. Instead all of the overall important dimensions are shown. Dimensions like
fillet radii and string distances are omitted since they are all actually very different on a real tennis
racket. The string distances vary by a couple millimeters each averaging 11 mm in distance.
