Are CNC machines ready for Fine Woodworking?
comments (90) December 28th, 2009 in blogs
Many folks equate CNC machines with mass produced cabinets and knock-down furniture, but professional furniture maker, Stephen Mosher of Hampton, Nova Scotia, Canada aims to change that. He told me that he turned to CNC machines 8 years ago when he got bored with conventional hand and power tools after working wood for more than 30 years.
His ShopBot CNC allowed him to make pieces that would be too labor-intensive to make profitably any other way. In addition to his own work, he also does contract work for furniture showrooms and he's willing to take on projects with hobbyists, too.
Do you think there's room for CNC in fine foodworking? Have you ever considered buying a machine or contracting some of your furniture making process, like making jigs or prototypes, to a shop that has a CNC? Please leave a comment and tell us what you think.

I am a CNC programer and machinist making hydraulic equipment and I can vouch for this personally. At the shop where I work, there is a gentleman referred to as "the old man" who operates the manual machines. He is the master of the mill and lord of the lathe, my words. I am constantly leaning on his experience and trying to learn as much from him as I can before he retires (which he always swears is next week, every week). I will probably never use one of the manual machines in this shop, as I tend to use the CNC's in manual fashion if needed, but I use the knowledge I gain from talking to a true craftsman in everything I make.
JeffB said "a project looses something when you simply program a machine to do some of the creative work." That is just not possible. Maybe you just misspoke, but if you are able to program a computer to be creative that is a true milestone in artificial intelligence. The design and creativity always comes from a human.
Robin9 made me cringe by saying "I can honestly say that there is little woodworking knowledge required when compared to a true craftsman, and next to no actual woodworking skill needed" and that "Soon fine furniture will be done completely by computer jockeys using CNC. There will be little to no skill required, no true craftsmanship." No skill required? The argument that many of those in opposition to CNC machines hold is that it cannot be done, not that it requires no skill. Furthermore it takes a great amount of knowledge and careful setup to get quality results from a CNC machine. Whatever skill is needed to complete a project by hand must be translated into a set of precise instructions that a computer can follow. If you are good, you can do it yourself; if you are great, you can teach someone else to do it.
schwa6970 writes: "I have been a furniture maker for 20 years and I dont think in my 20 years I have ruined this much lumber as they did in a typical work week. I firmly believe that cnc machines do not belong anywhere near hard wood of any kind." This reminds me of an old adage, "a poor craftsman blames his tools" with the exception that you are doing it for them. It would have been helpful to show these people at your shop what they were doing wrong and teach them how to fix it; just because you can control the motion of a CNC machine does not mean you can cut and shape wood. You had the opportunity to make craftsman out of computer programers, take the opportunity the next time it comes up and help keep quality woodworking alive.
I don't want to sound rude (failed) but the idea of a CNC machine as a magic green "start" button that churns out poorly made Swedish furniture is a misconception. Creativity does not come from 1s and 0s in a computer, skill is not as limited as some would think, and for every poorly made project you show me I will show you a craftsman that lacks skill and knowledge. Regardless of the tool(s) used...

If you think cnc is easy then try to program one.
If you do not have the software for a cad cam then g code.
Not all Machines use the same codes.
So ask before you buy.
You will find out that the Guy that thinks cnc is Easy or the programer is a dork or what ever you want to call him.
This guy may not even be able to add 2+2 alone do the math that is required to get where you want to get to .
If you can make a a product like some of the items shown on some of the cnc web sites. then more power to you.
I would like to see more cnc in fine wood working and how the systems work and most of the vendors want to keep there dirty little secerts as to how thy work so good luck.I have put stepper moters on a mill drill and made items.

CNCs don't operate any differently than any other tool that uses a metal edge to shape or cut wood. If you'r not getting the cut you want, then your not using the tool properly, or you'r using the wrong tool. I can turn a table leg in about 12 min. and do a set of them all the same. The CNC takes 90 min. and corners are not as crisp as the ones I turn by "hand". It depends on what the customer wants.
I once read "it's a poor workman that blames his tools".

That being said, I would *never* "make the jump" without seriously considering the cost, your temperament and computer savvy in the larger picture of your work. If you can buy a benchtop or small machine and you're not depending on it for income, good on you, eh? There is a LOT to these machines and the bugs and software can be, at times, frustrating beyond measure.
For the record, the people at ShopBot, without exception, provide THE FINEST technical support. Weekends, weeknights, holidays..... The SB community is truly an amazing group and the jobs and work done are an inspiration. If you are going to buy a CNC, buy a SB. You WILL need support, you WILL have glitches.
On the argument of handwork vs. having work on the CNC, I don't see it as an issue. It's ALL handwork. You might not be using a mallet and a chisel for every stroke, but you sure as hell will be using every erg of your skills on a CNC machine. CNC allows you to create and build objects and projects that simply couldn't be done by hand.
It is a thing of joy to be building something in the shop, having my wife working up a new job for the CNC in the studio, and have the CNC machine in the next room knocking out parts for speaker boxes.
We have a 5x8 CNC with a 3HP spindle and a lathe. Spindles are very expensive, compared to routers, but noise is a big issue for us.
We spent about $18,000 for the machine, shipping and a computer. Bottom line, would we make the investment again? In a heartbeat!

Unparalleled accuracy, minimum wasted time, material, and effort, and high quality output.
This machine will allow me to focus on the tasks a CNC machine can't do... what's bad about that.
Posted: 5:50 pm on January 13th
The use of technology to expand capability and improve my work product is ok with me. For example, I put digital scales on my table saw to improve accuracy over the ruler type scales. The scales did not diminish me as a craftsman in my mind but it made me happier with the results. I still use hand tools for some tasks if doing so makes me happy with the process and results.
The bottom line I think is that everyone needs to look at what they are doing and what it is about it that makes them happy. You use that knowledge to make your decision about what tools you use for your tasks.
In a production environment, I think that the decision process is different. I think, in the case of furniture for example, "fine woodworking" means the combination of fine design, fine materials, elegant details and robust construction. To me, the number of labor hours is not a measure of "fineness". If you want to do this with simple tools and lots of labor I cannot afford your product. If you create the same or better product at a more affordable cost using CNC equipment I'm for it.

On a different course. I think that sometimes CNC milled things look too perfect. The human body is interesting because its not perfectly symetrical. One side of the face is different from the other etc. Its the small flaws, the inconsistencies that constitute beauty. As wood workers we are always striving for a perfection we can never realize because of our hunman limitations. I think that's a good thing. I believe CNCs are here to stay in the business of woodworking, They are the new apprentice. But where do master craftsmen come from if not from apprentices?

Like so many other readers have commented: CNC is accurate - very accurate, and nobody with a handheld router can achieve the accuracy of a CNC, period.
Example: Darrell Peart, whom I personally admire as a fine woodworker, does much if not all of his joinery using a JDS multirouter? Does this offend the purist? Probably. But ask Darrell if he thinks the multirouter improves is joinery? I don't know how he'd answer, but I suspect he'd agree. Take a look at his book and the x-ray photos of some of the joinery from the Greene and Greene workshop - less than stellar in my opinion, but, it was done by hand!
In bending wood. How fast and accurate can you create 10 identical bending froms from a sheet of 3/4 mdf using a bandsaw and/or router? How long does it take you to build a multi-layered jig for bending? My customers could care less how my jig is made - the final product is what concerns them.
Carving? I agree with another poster: How many years does it take to perfect the art? Can you pass the hours used to create a single carving on to your customer? I doubt it. Have any of you "finewoodworking purists" ever ordered a finial from Osbourn, or some other vendor for a project? Do you think they have a staff of old world German carvers?
Need a jig for your shapper? Spend half a day making the jig and fine tuning it? Or, design it on a CAD program in 15 minutes and then cut and assemble the jig in another 15 minutes - ready for use? Or, do you despise the idea of using a shapper - or your router table in the first place?
I could go on and on, but I think by now you all understand what side of the discussion I fall on.
Yes, it's unfortunate that the world doesn't respect hand work as much tody - but it does! The world demands and appreciates fine hand work - they just don't want to pay for it anymore!

I would recommend a CNC to any serious woodworker, and especially the folks at ez-router.com
I echo epirnik "Is Finewoodworking ready for CNC" not the other way around!

CNC details are limited to what can be produced by a rotating bit. Crisp inside corners, for example, just don't happen on a CNC any more than they will with a router.
Sadly, the volumn of cheap furniture from China that is sold every day is a huge temptation, and many yield to that temptation.
True craftsmanship is still in demand, and thankfully, still alive.

Craftsmen are in danger. As CNC advances there will be less need for anyone to develop their skills. A furniture maker that utilizes CNC is not a Craftsman by any stretch; he is a designer/CNC operator. He designs it, programs it, the CNC cuts it and he assembles it.
If money is priority then CNC is the way to go. But for the small few that are in it for personal satisfaction and pride, that are in it for the journey, then CNC is not so good.
I don't get to keep the pieces I make, so my enjoyment and satisfaction come from the journey and CNC takes that away.
Posted: 9:13 am on January 7th
Sure I've got 2 dado planes that I know how to use, can hand joint and plane and again, have the tools to do it and I've hand marked and cut dovetails that fit nicely. But frankly, I've been there and done that - if I had the extra $8 - 12 grand, I'd have one in the shop today. Major timesaver.
Posted: 8:33 am on January 7th
These are people who typically "bond" with thier projects/work. They derive tremendous satisfaction from the experience of the journey.
Then...there's the rest of us. We love to create, and see the CNC as a way to be able produce projects we've only dreamt of. We know these new-fangled gadgets are a short-cut, but are willing to set aside our pride, and use the technology to take our woodworking to another level.
There will always be Traditionalists...true woodcrafting has survived for a couple thousand years of technological advance, it'll probably survive this latest intrusion as well. Heck, if I could purchase anything which TRULY eliminated end-grain blowout.....I'll leave it at that.

On the other hand, to me knocking CNC is like saying if Bach played a synthesizer rather than an organ he could not be considered a composer. A mind such as Sam Maloof's still reflected pure artistic talent which ever group of instruments or tools he chose to utilize toward an end result. Whether or not he used a spoke shave or a router to round a curve is irrelevant. Would anyone here dare to judge? The end result was pure emotion. Hmm, for that matter, much of his latter work was created not personally but by his assistants under his supervision. His design, the hands of others, so what's the real difference? As long as one possesses adequate fundamental woodworking knowledge and employs solid construction principles in the design, the computer is no less of a tool than any other in the hands of an imaginative mind?
On a final note, let’s not forget that there are many highly artistic and talented people which for one reason or another may be impaired and less able to use hand tools. At 57 my own arthritis sometimes reminds me I'm not twenty any more. I've always been a future child of sorts. In my mind, technology opens new opportunities. Bring it on.
Posted: 12:55 am on January 7th
Or, if you want another way of thinking about it, treat them as a router with an infinite number of built in jigs. I'd love one.

The key thin that people have to grasp is that a CNC is as much a tool as is sharp chisel, a mallet, a table saw or scores more. The tools simply make the task of the craftsman easier.
Do we deride the craftsman that uses power tools over one that prefers to human powered? No. Why? Because it is accepted and has been for some time now. No two craftsmen have the same methods to achieve same end.
In the end, yes.. Fine Woodworking is ready for CNC.
Posted: 10:24 pm on January 6th
I have already witnessed it first hand. A friend with next to no woodworking ability built a chest of drawers using CNC. Granted it was designed around the capability of the machines used, but that will change as technology advances. All he had was the knowledge of CNC programs/equipment and some theory behind furniture making.
My dog can chew better dovetails then he can cut by hand. Stick him in my shop and he's lost; he would not even qualify as a hobbyist and he's the first to admit it.
CNC will earn you money if that is all you are after. But personally, I need more then that. I could not take pride in a piece built with CNC, nor could I honestly sign my name on it. It would be like a craftsman signing his name on a piece built by someone else.

I am a retired Journeyman Tool and Diemaker and learned the skills to program the CNC machines. CNC requires all of the "Fine Skills" of the trade including the limits of the cutting tolls involved.
CNC raises the quality of precision cutting and in 1/2 the time. As the point was well taken after the CNC then the "FINE" finish is completed by hand.
For production the CNC will keep the shop competitive with offshore labor costs.
May God bless all our craftsmen and Happy New Year.

I would like to add my two cents worth to the fray.
I choose to employ CNC work for mostly the following reasons , it allows me to create things I could not or would not do otherwise. It frees me from tedious work , like cutting out kitchen cabinet parts. The resulting geometry , as in the first Asian sideboard , is perfect , which I love. Whatever work it is doing it allows me to do something else , thereby increasing the shops productivity.
I would like to tell you some other things about my work ( pictured here). First ,when I can , I do things " because it is my whim". Styles come and go ...and come back again , a little different.
In the second Asian sideboard the scroll work was the least amount of CNC working the piece. The underside of the top (in both pieces) was curved and textured with the CNC. The posts were cut out , and also the mortises and rabits and dodos were all cut on the CNC.The door panels were hand planed on the back to fit , just because I hadn't done that in a while.
I have friends who would be delighted to know I could make something "goofy" , this pineapple post I am keeping for myself and I am making two more , one in walnut and one in maple...and maybe one in mahogany. I was inspired to make this by a fellow woodworker in Florida who was working on a house that had five of these , at about $1000. US each.
I do very much enjoy the silence and peace of an all hand tool shop , some day , when I don't need to make money anymore , I may have that kind of shop. There is something to be said for the experience of handwork. Getting to know every turn of grain in a piece of wood.
It is never a matter of "simply" putting work on the table and letting the machine do the work. The programming of a project requires that every detail is dealt with before anything is done. Really you have to know the job to be done as intimately as if you were doing it by hand , in some cases more so. All in all I guess some things may be lost and some things may be gained.

The design process for a good piece of furniture is more difficult than many realize. The proportions do not just drop from the air. Like many today, my designing is software based [three different programs], though initially all my designs are a few scribbles on whatever piece of paper is handy.
Besides the 4-axis CNC machine I have, which I built, I have planes, chisels, squares, and saws galore. I love my Lie-Neilson block plane. Two tables saw, three router tables, jointer, planer, mortiser, jigs from Leigh and Trend.
A CNC oriented product requires one to disaggregate all the steps from design start to product finish. Think step-by-step about the simple task of picking up a piece of wood to cut it on a table saw.
With CNC, there is the design program, the design to G-code processor, and the servo controller controller program. And Lets not forget about feed rates, and fixturing.
Of course, Mach3 was a real treat to learn. I had hair when I started.
And, having used hand tools and power tools has meant that using CNC to realize projects has been easier. Tearout is tearout whether it is done with a no. 4 plane or a CNC router bit. There is still a right way and a wrong way to machine wood and there is nothing like a plane to teach.
Ultimately though, it is how beat to realize one's vision.

If CNC processes make a wonderful piece of furniture more affordable for a customer, then the customer is satisfied, will probably come back to the woodworker, who was helped his or her business. This seems like a win-win situation to me. In past centuries, the cost of goods was expensive and labor was cheap, which allowed for a high degree of ornamentation that is not economically practical now. It's one thing for a hobbyist to spend hundreds of hours building and detailing a dream project by hand, but shops don't have that luxury. The picture of the sideboard is lovely and I know several people who would be pleased and proud to display that in their homes. That the grills were done by machine doesn't necessarily detract from its beauty. Beauty is in the eye of the beholder, and if the use of a CNC system allows more people to patronize a custom shop, then yes, computer driven woodwork has a place in fine woodworking. It can't be the only tool in the shop, but its utility makes it a welcome addition.
Posted: 11:51 am on January 6th
My biggest enjoyment of the CNC is finding new and different applications which would be unachievable by hand. In my opinion it is a necessary tool in the future of custom woodworking shops when the workload and tasks at hand need to be done timely and predictably. www.prestigecasework.com
Posted: 11:28 am on January 6th
In my view, a hobbyist can justify the expense of a CNC if allows them to do more than before. TKReischl's example of "a dished area with a hummingbird feeding on flowers in 3D relief" is an excellent example. Carving takes a lot of practice to do well, and if you are inclined to spend the time needed to learn, you might just forego the carved panel. Having never seen a CNC carving aside from that produced by the Carvewright in a picture, I don't know what one would actually look like. They may (or may not) be quite fine, but I really doubt that it would be mistaken as hand carved. And certainly a hand carved panel would be distinctly hand made.
Have a look here at my latest project - a 5' long panel for a headboard. There's about 100 hours in this carving, by hand of course.

Even those organbuilders who build historicially inspired instruments, hewing closely to the practices of the Baroque era, don't rough out their lumber in a saw-pit and dimension it with hand planes. Nor do I know anyone who does the joinery by hand. I do have some colleagues who to produce what looks like a hand-planed surface, instead of sanding--and they use a wonderful Japanese machine to do it.
Technology is a good servant, but a bad master. Others on this thread have observed that they are glad to have learned to work the old-fashioned way before turning to CNC. I think that is very important. Who would want to be limited to only what CNC can do? To draw another example from my own field, we organbuilders face the question of whether to tune our instrument by ear or to use an electronic tuner. Tuning a large organ by ear is a fastidious and tiring process. Besides, the loud sounds can, in the long run, damage your hearing. Today there are outstanding electronic tuners, so accurate that you can put cotton in your ears. If I could afford it I would gladly use such an instrument. However, I cannot imagine anyone using it intelligently who hadn't first learned to tune by ear.
When considering the merits and demerits of using any sort of machine, we ought to recall that for the first generation of the arts and crafts movement (William Morris et al.) even the table-saw was regarded as a soul-killing abomination. I know of few artisans today who are that hard-core. But it depends on what you are out to acheive. If woodworking is a form of meditation for you, a spiritual practice, you might indeed decide to work entirely by hand.
In the end, each of us must ask, what matters to me? Of what does my integrity consist? Few of us do what we do just to make money, because, if that's what interests you there are a hell of a lot easier ways to do it. So spiritual values must be involved and that always means renunciation at some level. Most fine woodworkers have, willy-nilly, taken a vow of poverty. Many have practiced obedience in submitting to an exacting elder who taught them their craft. There remains the question of chastity, and I think that's at the heart of our worries about technology. And what is chastity? I think that the late Roberston Davies said it best: "Chastity is having the body in the soul's keeping." Who is in charge, we or our machines? Honest reflection on that question should enable each of us to draw his or her own line in the sand--or rather the sawdust. Then we must have the wisdom to stay on the right side of it.
Posted: 11:00 am on January 6th
What bothers me most is the fact that with a CNC, my hands and eyes are not on the work in any way. With a table saw, a band saw, heck - even a chop saw, my hands and eyes are on the wood. When I hand cut dovetails, or carve a ball & claw foot, my hands and eyes are on the work... but I am a hobbyist.
Perhaps that's why I enjoy this hobby so much (and don't really mind not having a CNC machine).

Is Stephen in control of the machine or is it in control of him? Resistance is futile, you will be assimilated?
The grill work on the first is interesting at first glance but also kind of funky. And a chimp can tell it was done by a computer, nobody in their right mind is going to take much time out of their life. And, as always with this stuff, it looks too perfect. Is it wood or is it injection molded? Don't get me wrong here, the sideboard itself is beautifully done, obviously the work of a talented craftsman.
The pineapple is just goofy, we won't waste much time on that. Do we need wooden pineapples in 2010?
What is European looking scroll work doing on an Asian cabinet? Shouldn't it be dragons or something? Again, the work of a brilliant craftsman but one who apparently didn't have a 3D model of anything Asian.
If this is what CNC does to you then it's dangerous and should be banned. I thought I wanted a CNC, even considered building my own, but if this is what it does to you then no thanks.
Just what is a CNC capable of? Could Stephen have used it to cut out those tapered legs? What about the door parts? What about the tops of those sideboards? If it can do those things then I'm interested. But if all you get is funky pineapples then no thanks.
I'm of Irish descent and I'm afraid that the temptation for me to have the machine cut out some goofy Celtic brickabrack and ruin some otherwise nice piece with it would be too great to resist. Then my hillbilly friends would ape doodoo over it and I would be ruined.

Several posters here seem to think that one just throws the work on the machine and PRESTO! instant results. If it were only that easy. Actually, it is if you are making curb furniture out of sheet goods. Anything beyond that requires considerable planning and preparation. The wood still needs to be flat. Panels still need to be glued up. Attention has to be paid to grain matching. Then there is one other thing to be overcome: Trying to make it look like it did not come off a machine. This is the same challenge faced by anyone who makes things with power tools.
There are some tremendous benefits to CNC machining. It can replace having to build jig after jig to obtain precision cuts needed to build things such as chairs. With the right software and some time spent learning it can just as easily carve a beautiful cluster of grapes in 3D on a panel, or even wrapped around a column. How many one man shops have the time to master all these skills in a lifetime to produce beautiful results?
But here is where the Fine Woodworking comes in: When the machine is done carving, one can always pick up a carving tool and do some Fine tuning to that carving. Some things are still faster to do by hand, so one should know how to use hand tools.
Over the years I have noticed that woodworkers keep looking for the "one tool wonder" of woodworking. It doesn't exist. One might as well go in search of the Holy Grail.
An example of using CNC in Fine Woodworking in my shop was a recent project for our new home. A simple bath cabinet taken from plans in a popular woodworking magazine. I built the entire cabinet conventionally, no CNC until I got to the panel in the door. Then I wanted to carve a dished area with a hummingbird feeding on flowers in 3D relief. I let the CNC machine do that. It took me about 2 hours to do the design and about 3 hours of time on my home built CNC machine. The results are fantastic, my wife just loves it. Yes, I could have cut the contoured side panels on the CNC, drilled the shelf pin holes, cut the dadoes etc. But frankly, it was just as easy to do it conventionally. Besides, I enjoy doing it that way. If I were making 20 of those cabinets I would have done it entirely on the CNC, because it would not have been much fun after the second one.
So you bet that Fine Woodworking is ready for CNC Machines, in fact, in my opinion, it is a moot point.

If you enjoy cutting dovetails by hand, you should but don't get all huffy when some people are not impressed. My grandmother used to make her own bread when I was a kid. She was thrilled when she could finelly buy sliced bread from the corner store. I get the feeling that some of you are still using the foot powered lathe and look down on anyone who doesn't. Farmers use tractors instead of horses and plowshares, it is called progress.

I think that CNC should be viewed as a tool that could be used to help release our creative and artistic designs. It should fall in the same category as our other power tools.

I use my ShopBot in my business of making hand weaving looms. Some weavers view their looms as tools and others as fine furniture. It is all in the customers viewpoint.
I do not make all the parts for the looms on the 'bot, only the ones, and only those steps on that part, for which it makes sense to use the 'bots capabilities.
To MLZettl, he's absolutely correct, CNC is a tool...no better than the workman using it.
My ShopBot does only what I tell it (program it) to do. However right, wrong, brilliant or stupid the instructions may be, the 'bot brainlessly follows those instructions.
My Delta table saw cuts only what I push across the blade; right, on the line, wrong, not on the line, brilliant, exactly the right angle and length, stupid, thumb.
My chisel cuts only where I place it; see table saw above.
To tkarlmann, is not the hand wood carver just "cutting out a part from a block of wood?" What does he do with the "huge part left over?" I submit, just like the CNC craftsman, he cuts another part out of it. Do any of us just cut a small part out of a big board and throw the rest away? NO, we all have scrap bins that we constantly pull from. As to "those finishing coats of spar varnish," I submit you have a car in your driveway or garage that had the "finishing coats" of paint and clear coat applied by a CNC machine. It's all in how you, the craftsman, use your tools and what tools you choose to use to do the job at hand.
To Fine Woodworking; the first poster, epirnik, summed up all the later posts most clearly, Is FINE WOODWORKING ready for CNC machines?
Off to the shop...

I know I can do everything by hand but when I've done it once I don't feel the need to do it again.
Each to their own. If we stretch the meaning of craftsman to include those who can do amazing things with CAD/CAM software then we're covered.

I also think the CNC is more than a "power tool." Too often the phrase "power tool" is used with distain, to mean "hands free," as if the woodworker has nothing to do but turn the machine on and go have a cup of coffee. But in fact most power tools ARE hand tools. I don't know any hands-free table saw, hands-free mortiser, hands-free jointer etc. etc. We lay our hands on the pieces and guide them through these tools with TLC. One slip and a nice piece of wood is ruined. The CNC is totally hands-off, as best I can tell, though I confess I've not used one. For me, the joy of wordworking comes from using my hands. I don't think I'd get nearly as much pleasure watching a robot do it, though I have to say the finished product is certainly nice to behold and the time saved is probably a deal-maker for the pros.

Designing, whether on paper on on computer, is still the major challenge for me (and many others) and even more so on the computer where a whole different set of skills is required to even start. Poor design executed with the finest skill is still poor design.
So I speak from experience, CNC is a neat tool but that is all it is. It requires a very steep learning curve and is not cheap. Final evaluation though: I can't do without it!

The danger comes when you start to say things like "How can I use this more because it saves so much time?" Then you end up with a chair that is designed for ease of manufacture rather than comfort and elegance.

Main difference now is that swearing at your cnc machine isn't as satisfying as swearing at a clumsy apprentice.

What's the difference in making mortises using a router with a template, a Multi-Router, a mortising machine, or a CNC? When you think about it, there isn't really any substantive difference. Sure, you can chop the mortise by hand, and if there is only one to do, I'll do it that way. But if you have to do over 50, as there are in a sideboard that I'm currently building, using the CNC machine is far more efficient. Once everything is assembled, no one will see the mortises anyway. Even if they could, would they be able to distinguish them from other machined type mortises? I doubt it.
I enjoy hand woodworking. I like the peacefulness associated with it, and the pride that skillful work brings. But, I also think that being practical has it's place. I think that by any measure, my work would be considered "fine woodworking." The fact that some operations employ CNC technology has nothing to do with it in my opinion. How many woodworkers actually build using hand tools alone, and I mean from the felling of the tree with an ax all the way to the finished product. I would propose that there aren't too many. The point is that most of us use power tools to some extent. They are an extension of our capabilities, and a CNC machine is simply one more power tool.
Any tool, no matter how simple or sophisticated, is no better than the workman using it.

I am not a purist. I use the best tool for the job, but to a point. In my opinion CNC not only takes the skill out of furniture making, but also the heart and soul. I take far more pride in the furniture I make using my band saw and lathe then using CNC.
I have been dreading it for a while now, when CNC will become affordable to the small custom makers. I think very few will be able to resist the temptation to change over to CNC. It does offer the opportunity to produce faster and make more money. As Technology advances CNC machinery will become more affordable, and also capable of doing a lot more. Is fine woodworking ready for it? Is there room for it? There had better be, because unfortunately, it is the future of Fine Woodworking.

I can think of MANY applications that CNC machines are useful for, but here is the rub: On most of the examples I looked at on YouTube, the CNC machine is cutting out a part from a block of wood -- NOT very "Green". What do you do with the huge part left over from the CNC 'cutout'? Is this just "waste"? How economical are CNC's in terms of, not just my time, but wood-as-a-resource?
A CNC machine is not going to help me make bent-wood laminations, or help to put fancy veneer over a base, but it sure would come in handy to make a wooden gear! Now, if it could make all those finishing coats of spar varnish ... and sand in between coats ... sure adds noise and mess to the shop too. Is that Fine WWing -- to cut some fancy shape from a sheet of plywood? (I know, I'm being negative -- just trying to make everyone think a bit.)

CNC is another tool. It requires knowledge of wood and joinery techniques just as hand-work does. The software and machine setup are not trivial skills, but also require knowledge and hard work to be proficient at.
I've worked at CNC production in residential framing for over a decade now (timbers, logs, SIPS, stud framing...). I can design a furniture piece, then automatically get exploded diagrams, detailed piece drawings, and even CNC instructions (which I could use if I had my own machine). Disagree all you want, but I know in my heart that I am a craftsman.

I remember when I was a kid at convention in North Carolina I saw this man carving very impressive bowls, spoons, and other kitchen utensils by hand. I remember thinking how cool it would be to do that myself and now almost 20 years later I still wouldn't be able to make something as precise as he did by hand, but I could most likely program a CNC machine to do it.
So I think that when someone that can't do it by hand can do it by computer/machine it loses value overall. Not all value is lost because it is most likely more impressive when done by machine than when done by hand, but a little bit of value is lost when the machine does it rather than your hand.

I could reference an extremely valued table made of baltic birch ply, but that would turn off (I'm guessing) 85% of viewers in the forum. Oh no, if MDF if mentioned.
Tony hits on the key issue of the size of the machine and another fella below mentioned the amount of clean-up. Costly right now.
The dilemna to a question like this; is that the indivdiual on this forum, isn't the "buyer"/"market" for forward thinking furniture objects.

Let's say it takes me a week to carve some kanji by hand on a box where any slip is going to ruin the piece. Compare that to a CNC pattern that takes a few minutes. If I make a mistake then I can just do it again. No big deal. Maybe I'll even be tempted to add more kanji, just because it's easy. I like to think that the former will carry more meaning and make a better heirloom.
I think context is everything on this matter. Sometimes the end product is all that matters. Other times, the process is as important.

An elderly gentleman once told me 'romance sells’, it doesn't matter what one used to build things it was how the client perceived its making that counted.

It's been many years since I had any dealings with a CNC device, and that was in a metalworking context, but I highly doubt that the grillework in the project above came off the machine looking as good as all that. It probably took some fine-tuning, some cleanup, etc. Some "fine woodworking," you might say, to finish it up. I think most people would agree with me that regardless of method, results are what truly defines whether something is fine woodworking. Methods are important, and methods make a great story to go along with a piece, but in the end, it's all about the piece itself.

Received my copy of Craftsman Furniture and love it. The quality of the paper and pictures is outstanding. The projects contained in the book are excellent. I will use this book a lot.
Many thanks,
