Well, Peter, if frogs had wings they wouldn't flop their arses
when they landed, you know?
Thanks for the inspirational imaginery JJ. Perhaps your baroque
flying frog will be my first figurine and no doubt a best-seller in
all gift stores.
The technical advice you gave corresponds more or less to the stages
we see in the video of the Carso lathe carving a bust over 8.5 hours.
They describe four stages. Each stage involves a hand-on human
intervention. As long as the seller explains the stages required for
the machine offered with a ball-park estimate of the time/cost for
each human intervention the problem is solved as far as management of
costs is concerned.
CNC means Computer Numerical Control.. But the other NC in the
transaction is a cost accounting NC (also in binary though the
language is Dr/Cr rather than 0/1). Two others from Orchid have also
offered helpful advice off-list and it is up to them whether they
wish to join in the public discussion. That "human intervention" in
the stages of automation was also referred to. It may vary somewhat
from machine to machine.
It was also stated that this technology is not so new or cutting
edge. True as a generality on 3D scanning and printing. But not when
it comes to cutting/grinding stones with CNC machines. Have you, JJ,
ever completed a flying frog or other figure in stone with a CNC
machine? Has anybody else on Orchid? Nobody has come forward and
off-list I have only heard of two people who do this work regularly
and they are not in North America and there are associated
That takes me back to the analogy with a personnel decision. For all
important personnel decisions we get references and even if it is a
first-job situation the educational record of the new graduate is
the reference. However, I am close to making a purchase and mainly it
is that personnel reference that I await. If pick up the phone and J
Doe says, Yes I use the JJ CNC machine and it works very well with
stone, and better yet Doe says I will make a sample flying frog from
your material, then I am sure beyong reasonable doubt that I am
making a sound purchase. That is why I keep coming back to Orchid
with this topic. I am trying to "hire a robot".
In all this time not one person out of 13,000 on Orchid has said, I
use the CNC machine regularly in my business with stone and I will
tell you about some of my experiences. Thus I conclude that this is
new and that those videos we see are mainly sellers' demos.
One final point on your reply re "custom making" as my goal. That is
not the case. The original artists do the custom making in wood or
clay. I cannot expect them to do it as CAD on screen because they are
not that kind of artist. I want to then scan and replicate
(preferably with a software option to enlarge or make smaller) by CNC
machine. There are reasons other than commercial reasons for this.
Remember the story of Quianlong's giant jade bowl? He had it hand
replicated which also gives some protection against theft or breakage
of the original.
