Is there any indication as to the ratio of CAD/CAM labour to hand
crafting for "Undulation"?
I find that in the CAD /CAM / MACHINING process, the labor varies
greatly just as it does at the bench. There are simple pieces of
jewelry that (if you need just one) it is about as fast to carve by
hand as it is to us as the CAD /CAM process. But then, there are
those pieces that are more complex that will take an hour of CAD /
CAM and 4 hours of actual machining. Lets say a class ring with a
lot of fonts and textured background… If you have carved one…or
fifty of these, then the CAD /CAM system has won out big time time
wise…and most likely has produced a better model. Better because
the fonts will be cleaner and more consistent than by hand carving.
As far as “Undulation”… it really doesn’t matter whether the
piece is undulated or not. CAD /CAM, nor machine really care. The
model is drawn, a tool path established, NC code is generated, fed
to the machine and the machine does as it is told. It couldn’t care
less what the style or shape is.
There are those times that as with many bench tools… CAD /CAM is
not required or really feasible to use. Part of the learning process
is knowing when to reach for CAD /CAM…just as knowing when to
reach for a file, graver, prong pusher or any other bench tool.
CAD/CAM/ MACHINING is nothing more than another bench tool. That is
the first thing I try to always get across to new users. It is just
a tool. Use it when it will save time, money, and when it can do a
better job by producing a better model and finished product for the
