Scott or anyone,, I have hundreds of things i made that i would
like to have symmetrical opposites(rough) of,, CAM must be great
for making or roughing symmetrical opposites of 2 or 3d carvings or
objects, for earrings,, yes?? I could see that saving alot of
time.(FTC ALERT) Do many people rough out complex 3d design shapes
in wax, with CAM, and then handcarve to the finish?? And refering to
scotts's statement,, how much would it cost to get a maple leaf,
1x1", 1/8" thick, or even a cube, 1x1x1, hollow inside, with all
sides(or 5) represented as pierced grids or bar patterns??dp
Once a CAD model file is accomplished, the creation of opposites is
produced using the 'mirror' command, about 3 seconds work!
In order to make mirror opposites from your existing pieces via CAD
would require the re-creation of the original models in CAD first, at
least in respect to being 'exact' opposites. Perhaps some of the
pieces could be 3D scanned, but there are many factors to consider,
such as shrinkage, finishing, etc.
I personally try to avoid hand carving totally when designing with
the aid of a computer. One can simply not carve to the accuracy of a
CAD model. At times though I machine some components of a piece and
hand carve the rest. However, I feel compelled to say that achieving
a hand carved look in a CAD model can be extremely difficult at
times. CAD, is simply another tool, like a saw or file, and requires
substantial practice to master, or to even mimic what the hands can
find easy to do. CAD models have a certain use, as does hand carving.
For instance, it is highly unlikely that machining can ever replace
artistic hand engraving.
A Maple Leaf, for instance, is struck from a steel die that has had
much finishing, a rather lengthy and exacting process. Yes, it can be
done, and I do commerative coins and have some experience with
coining, but would not consider making a Maple Leaf. Substantial
equipment and time is needed to take a coining job from start to
finish, i.e., the CAD or tracing model, the engraving of the die,
finishing/polishing of the steel die, the making of the planchette
(blank gold slug), the die set and coining ring, the 300 ton press,
etc, etc, etc) A huge process...
A one inch hollow cube formed of pierced sides must either be
fabricated (possibly from machined components) or 3D printed (Rapid
Prototyping), and in certain unlikely cases can be machined as one
piece. My specialty is no longer exclusively milling, but production
of prototypes from 3D wax printing (see the process at
