Group,
It has been interesting reading all of the posts in response to my
reply to James Binnion concerning CAD/CAM in this thread on FTC
guidelines. I have enjoyed the banter (and my roasting). There are a
number of posts I feel I need to respond to and a array of topics
brought up which I should address. I hope I do justice to them all
with my response; and I apologize for what will no doubt be a very
lengthy response.
To put some perspective on my response, let me say that most of my
CAD creations have been in the one-of-a-kind category (the same as
my other jewelry work and the same as, the apparent majority, of
people on this forum); I do very little in the way of mass
production. If I am asked for production work, I send that work to
Dan Grandi ( Racecar Jewelry) because that is his specialty; some of
my clients send to China for their mass production (sorry, Mr. Wismar
and Mr. Grandi! I don’t like that much, either). Fact of life, for
the time being, is Chinese production helps some people’s bottom line
so they will use that inexpensive production method and I have no
control over that (I’ve tried). This too will pass, as the Chinese
economy is now experiencing inflation at a significant rate.
That said, please take note that I never stated that CAD/CAM created
jewelry objects should be called handmade. What I did say is: “I
don’t think most of my CAD creations could be differentiated from one
of my hand carved/fabricated pieces…”; to which Jon Donivan
responded: “…I’d have to say that this is the reason we have an
FTC it’s regulations. Handmade=made by hand. Machine made=made by
machine. Why does it need to be said?”
It doesn’t need to be said, John; that would be a horrible ethical
precedent if it was assumed that no disclosure need be made about
the about how a piece of jewelry is made or to misinform clients
about how their piece came to fruition. There is a lot of handwork
that goes into taking a CNC machined wax or printed model forward to
a finished piece of jewelry; still, I don’t know that I would have
addressed my work on a “handmade vs machine made” basis without the
prodding from all of these posts. I do distinguish for my clientele
between the different methods I use to create all of my jewelry. My
clients all know if I am machining, hand carving a wax, building from
stock metals (whatever) their piece of jewelry. They also know that
the design I sell to them is theirs and theirs alone…the design
sells along with the object unless the piece is from one of my
previously-designed lines or they prefer a discount by not purchasing
the design rights along with the objects That is for my retail
clients. My wholesale clients always own their designs and usually
determine for me the way they want the object produced. Anything else
would be unethical.
Not trying to remain humble, perhaps the difficulty distinguishing
my CAD from my fabricated work is because my bench skills have
evolved over the past 34 years to be on par with with what today’s
CNC machines can produce for the independent jewelry sector (or maybe
it’s just that my eyes are failing me as badly as my arthritic
fingers are…yet, still, I only have a mild reading glasses
prescription, and that is very recent).
All kidding aside though, I responded to the expressed thought that
"CAD/CAM to finished jewelry" requires less skill and attention
throughout the process than does bench work as we traditionally know
it. I said: (now in condensed form) that the CAD creator needs to
supply as much skill and attention to make the virtual design
flourish as an actual object as does any person carving a design from
a solid block of metal or fabricating from standard stock forms (I’ll
touch on wax carving/casting in a later post). My original post in
this thread was in reference to (or in deference to) Jim Binnion’s
post where he stated (now in paraphrased form) that hand work
(whether it be with non-mechanized tools or with power equipment such
as watch makers lathes or hand mills) requires a higher level of
skill and attention to detail than does producing the same item via
computer aided design and machining. It’s not higher skill, it is
just different skill. Jim does go on to say in another response to my
post that “Programming and setting up CAD/CAM systems require
significant knowledge and skill and yes it is very possible to screw
up and ruin a piece with them but once the program is debugged I can
set up my CNC lathe and walk away from it and it will cut a perfect
rendition of what I programmed into it 999 times out of a thousand.”
Jim, thank you for acknowledging that there is some skill and
knowledge involved in CAD work. It wasn’t easy getting up and
running at the beginning of designi with CAD (I use Rhinoceros); it
took me a full year (working 3 to 4 hours per night) to feel
confident enough with the program to use it for customer jobs; while
it took me only about 4 months of practice to feel confident enough
to hand engrave my first shotgun for a customer. It took even less
time to feel proficient doing a bead and bright cut setting, forging
a wire, or doing raisings for sale.
Referring to the “999 times…”, I’d like to point out again that we
are not referring to manufacturing in this thread, but rather to
single piece work done by an individual artist. Just because it CAN
be used that way doesn’t mean it WILL be used that way. As an
example: anyone can rubber mold a cast piece, a hand fabricated
piece, or a solid-block-carved piece to go into manufacturing just as
quickly and easily (and often more cheaply) as re-machining or
printing pieces from a computer file, so your point is moot, IMHO, in
this thread because no matter the method used to create the original
work, the work can be used to mass produce a facsimile of the 1st
item, if the original is of sufficient quality. Now to split hairs
here, we’re not programing the computer when we do the CAD portion of
CAD/CAM; what we are doing is taking a a computer and the resident
design program and using their abilities to do the background math to
define the surfaces of the object we are visualizing. We draw the
piece (in 3 dimensions) the same as we would for a working drawing
done by pencil. When our drawing is completed to our satisfaction
(and if the design program we are using to draw with doesn’t have too
many bugs) our design file has the mathematical surface information
in it to export to another program with which we then DO program the
tool path to cut or print the piece our hands created on the screen.
In manufacturing, it can then be reproduced at the 99.9 percentile of
accuracy. But I digress, because we are still talking one-offs.
Bill Wismar suggests: “Personally I think it should be disclosed that
it was computer generated and cut.”
Bill, I do let my clients (wholesale or retail) know when I intend
to create for them using CAD/CAM, its a great selling point. Bill,
you say in a later post: “…You and others who support cad or
whatever is next will be screaming about how bad business is in a few
years. If the buying public is led to believe that all jewelry is
handmade no matter how, we will loose in the end…”. Bill, just let
me say that I find that the vast majority of my clients are in awe
that their jewelry is going to be made by a computer because they
have a hard time imagining how it can be done. When they see the
rendering of the proposed jewelry in near photo-realistic form they
are awed even further. Then, finally, when the finished object looks
exactly like the picture, and it fits, and has all of the elements
they desired, they are very impressed that all of this was done
through the use of a computer. (little do they know of all the hand
work that went into the piece after the computer did its handiwork).
A few have a difficult time seeing the enlarged version on the screen
and imagining it small enough on their hands (“Wow! that’s really big
and heavy, isn’t it?!”), or are disappointed when the actual object
looks so much smaller than they imagined (“I thought it would be
bigger than that!”), but I find those are the same people who
couldn’t look at a hand rendering and imagine it in 3D to begin with.
Most are thrilled that I could get a computer to do all of that, when
they have a hard time downloading or uploading email. By and large my
clients are thrilled to have their work done in whatever manner I
choose to use to make their dreams come true for them to wear. My
business’s profit nearly doubled (up 47% in two years)once I started
using CAD/CAM. It is still producing about 45% of my sales. I’m
afraid those who fear CAD/CAM may be the ones “screaming” in a few
years.
I still fabricate a large number of my custom pendants and rings, I
still do a lot of hand carved waxes and casting; I still hand
engrave (without a GraverMax or any power assist), and I will
continue to move metal until I’m unable to use my hands. I still
thrill about metal as much as I did when I first started learning
this trade in 1974. My biggest thrill is still:- though metal seems
so inherently hard, it can also be so plastic. I don’t fear the
future of either my hand skills or my CAD/CAM. When your hands and
mine are useless for moving metal, I’ll still be able to design on my
computer and have one of my skilled apprentices finish the metal work
for me. I’m 53 years old now, and I plan to be working metal and CAD
well into my 70’s; arthritis willing. I’ll pass along my metal skills
to anyone who asks, because I enjoy sharing my trade.
James Miller, a most respected goldsmith from the U.K. worries “I
think (CAD/CAM) will kill off many of the hand skills of the
goldsmith. Skills that have been passed down through the ages…”
James, not to worry. There is not any viable computer replication
for hand chasing or repousse, nor for granulation (even though the
mimic can be construed as close), nor for mokume-gane, Mr. Binnion’s
forte. CAD/CAM can’t yet assemble, finish, or set stones as well as a
skilled craftsman. It can’t reticulate a sheet or choose the best
part of a reticulated sheet to use for the design. CAD/CAM can’t yet
enamel. Stamping machines used for over a century to mass produce
silver service sets haven’t yet totally replaced hand craftsmen
raising teapots, chalices, or pitchers. How is it that you perceive
that CAD/CAM will then? There is so much CAD/CAM can’t do, that I
don’t fear that goldsmithing talents will get lost, we will need
smithing skills far into the foreseeable future. The sky’s not
falling; it’s actually getting higher as we raise the ceiling of
things we can accomplish in jewelry and metalsmithing in ways never
before dreamed of.
Kevin P Kelly wrote in that “If we’re doing it right, our work that
is, the process changes us. I don’t see how CNC contributes to that
experience. My underlying assumption is that we attempting to carry
on a tradition of handwork; not faster and more cost effective.” I’m
sorry Kevin, but I am in business to stay in business and the goal of
my business is not only to produce happy customers and to practice
the art and craft which I’ve learned; BUT I also have a goal to
provide a good enough living to support myself and my wife in the
best way and to the best standard of living which I can achieve. Long
before I learned CAD, I learned ways to speed up my hand work so I
could produce up to 5 custom pieces of jewelry each week, all in the
middle to high end category ($1000.00 to $80,00.00 wholesale). On top
of that was all the standard repairs and some restoration work I
needed to accomplish to assist my clients and keep a good working
relationship going with them. I needed to be fast and efficient; and
because I was performing for jewelers from all around the country, I
also need to be better than just “good” at what I did. They know what
is quality and what isn’t, so my work had to be excellent enough to
pass muster for at least 23 jewelers at anyone time. I’m a realist
and I like to eat well while living in a nice house in a nice
neighborhood. Sorry.
I like to keep the tradition of handwork going, too. I also realize
there are sometimes better ways to spend my time that beating a dead
horse. If a methodology has the potential to make my life easier
while still putting out quality work for my clients, I WILL use it
once I learn it. CNC has changed me in the process, Kevin. It has
broadened my horizons at a late stage in my life. It has kept me open
to new ways of thinking about problems. I now have time to write this
lengthy treatise!! I also have had the great opportunity of meeting a
number of other fine pioneers in the jewelry CAD/CAM field and have
had the mind broadening experiences of learning numerous programs and
getting my feet wet about how they work in the background to help
create what we see on our screens or machine out of wax or metal. I
have seen the directions that are proposed for future methods of
depositing metal rather than cutting it. The CNC learning process has
opened me up at least as much as my college experiences did. That’s
quite a contribution!
Bruce Holgrain posted: "Me for one. It is absurd to consider a
machined wax part of the process of hand making an object. That part
is still machined. The FTC has a category for this object. They call
it “hand crafted”. "
Bruce, it is absurd, isn’t it!? How can one cast some components,
lathe others, pick up found objects, clip out pieces from papers and
magazines to use as collages in portions of their jewelry creations,
or even (god forbid) use CAD/CAM components in their work and still
call it hand made. Look at Richard Mawdsley’s work; assembling all
those components that he cut with guides and his lathe turned tubing
pieces that create images of bottles, buckets, a calliope. How can
that be called hand made not just hand crafted? Bruce, if I do an
entire piece by CAD; there is no way to call it hand made. If I CAD a
part and machine it, then use it as a component in a fabricated
piece; I think that qualifies as hand made as nicely as any other
assemblage of non-mass produced parts. I CAD a number of pieces and
after finishing the metal product I’ll hand engrave it for total
coverage because the machined imitation of engraving does not come
close to the look or feel of a hand engraving job. Should I not note
the hand work involved? In a post from you today you asked: “Has
anyone ever considered a milled or lathe turned object handmade? I
have always thought that was ridiculous.” Yes, as a matter of fact,
James Binnion (whose post got me to write in this thread) did just
last Friday: “If I make that same part on my watchmakers lathe with
hand held gravers and a “T” rest it will require my total attention
and skill to get the part made and if that attention wavers or my
skills are not up to the job it will be ruined or of less than
desirable quality so making that part has a high degree of risk
involved and is definitely handmade.” while comparing CAD generated
work to his lathe generated work. Take that question up with Jim;
I’ve found it very rewarding getting into this discussion with him.
Rick Hamilton wrote: " I think that the FTC guidelines are fairly
clear, CNC is out of the realm of “handmade”. A keyboard is not a
hand tool in the way that a hammer or engraving burin (SP) is.
CAD/CAM is a manufacturing process even when one piece is the end
result. It is nice that the FTC has a 80/20 % rule about manufactured
findings, but really, soldering a few die struck pieces together
isn’t handmade, and neither is a jewelry item made from a computer
controlled machine…"
David Phelps wrote in today that with extensive research into this
topic in the FTC regulations "Nowhere did I see a prohibition of CAD
CAM, or casting, or even a prohibition of mass produced jewelry.
Nowhere did I see a prohibition of power tools, electric or
otherwise. I also saw no rule stating that only fabricated pieces
qualify as “hand-made”. Nor did I see any mention of the “80 - 20
rule”.
Thanks for the research David!
I fully agree with you that we are not legal beagles and that this
discussion should be between attorneys and a judge in a court of
law; where the emotions of the involved parties are ignored and the
realities of the processes involved could be deciphered.
As with the casting vs fabrication issue, this one on CAD/CAM will
be on going for quite some time. I for one am very glad that I took
the plunge and started to discover what CAD/CAM has to offer. I am
very glad I am able to combine it with my traditional skills and am
open enough to try. I am grateful for CAD/CAM helping me for less
expense than an employee. Having arthritis as bad as I do now, and
having nagging tendinitis, it has been a godsend to me; helping
produce my “waxes”.
I’m also very glad that I didn’t invest in the buggy whip business!
