I like it. Very cool.

[myxpykalix]

I like the design, what program do you model in? Now that it is modeled how would you set up the parts to be cut? Good job!

[fabrun]

thanks
only solidworks is used

machining could be easier with female part for locating

[bleeth]

Nicely done. Looks like with some minor modification to the mortises all the pieces except the legs can be done flat.
Jack: Wouldn't the legs be a snap on the indexer with 4 90 degree turns?

[myxpykalix]

DOH! Thats why I asked...lol Isn't it funny how great minds think alike Dave?:confused::)
I have seen Solidworks being used on shows like American Chopper (pauly what are you thinking?) and they design alot with it so i'm sure there is probably a component that will also toolpath the parts.
I like the exploded view for parts also. Maybe Fabrice will cut this table out and show it to us completed.

[john_hartman]

It is pretty cool. I would like to know how you would cut this out on the bot though. Aside from the top; is it even possible?

[dlcw]

Put a sharp blade in and tune up the bandsaw for this project. :)

[gc3]

yes it's possible with a little luck and a lot of thought you can build a index jig to mill the parts without a rotary...

i am still a newbie but have been experiementing with 3,4,6,8 sided jigs from ply's to cut parts similar to these.

one advantage of having a vintage machine and a very limited budget is that you put your skills and imagination to work in a hurry ;)

When I was younger living in Edmonds, Wa, long before cnc, hidden away in what was once a forest resided a furniture mill. Some guy did just as you describe and made one.
This piece was then fixtured to a long tool kinda like a router/pantograph. Next to it was chucked up about 20 or so solid blocks of wood to 20 router heads. The shop was powered by steam and leather belts. Scrap powered the steam plant. First, the machine hogged out the blanks with router type bits and then the fella switched bits and it picked up the finer points.
It didn't take very long. Some hand work. Next door was a huge pile of furniture parts. It looked like Santa's workshop.
But what do we know?
Now, a Hooters, a gambling casino, a Pay Day Cash joint and a now defunct mortgage company take up the space.

I guess my point is....an indexer sounds great but using the program to create a bunch of fixtures and make enough table legs to make the first one pay.

Can people still make a living making furniture? My wife just bought a recliner made in Monroe, Wa. Obviously fabbed by CNC...what a POS! (The Design) I didn't have the heart to tell her she wasted our hard earned dough.

Fabrun's design will be killer if the joints are seamless.

...Well,...Chuck I thought Gary ended your chances of ever posting here again

Wrong

Some day I will post my simple, ahhh POS jigs here even for you to see and maybe include the .sbp file for making the same jig, parts/carvings

So have you purchased a machine ? Si o no? How about posting photos of projects you have done...with any tool

Gene

[rb99]

He should get an old pr with a 4g box. You do beautiful work with yours Gene. Chuck is so keen about cnc, this would let him in the game without breaking the bank...

The table is very nice.

RIB

[fabrun]

thanks for all
there's a lot of component for toolpath as plugin for solidworks (not included)
i'm using visualmill for that
i don't have a cnc yet so i can't show you the part cut
but i'm sure it is possible with a 3axis
fabrice

[jnbish]

Gene,
Right On !

[navigator7]

Regarding the Fabrice's sweet looking legs........I see four sides that would respond to carving via 2.5D.
Attached is a simple fixture idea for a 4x8 table used to hold slugs as they are machined.

I hope to get a 4G box one day...

Chuck, I like the thumbnail photo title, looks like to me you "save picture as" that design from cnczone

Hi Cranky! ;-)

Nope
Ashlar Vellum Cobalt.

So, Gene, what do you think?
There still is a lot of hand work making the raw stock and a little air cutting.
Does something like this substitute as a poor man's indexer?

Not sure about the indexer...yet, but I can show you something I have done by hand and one big reason I have taken to cnc machining!

Well Chuck, it will cost you $50dlls but if you donate to Friends of the Creek you have the chance to win a cnc machine...then you can crow as you please.

In the immortal words of that great philosopher, Rodney King..."Can't we all just get along?" lol

Gene...that picture is painful just to look at let alone have to have experienced. That happened in 2009 where are you at in your rehab of the injury? Hope things are going good for you......

Gosh Gene...sorry for your injury.
I'm 55 years old and have machining, welding, ship building, crane work, tug boating, concrete pumping, deep sea diving, deep sea cable laying and a few other skills I've forgotten about. Yet I've never been injured or even seen such injuries. I'm afraid you have a leg up on me!
I guess I do have lots to learn from you.


Well Chuck, it will cost you $50dlls but if you donate to Friends of the Creek you have the chance to win a cnc machine...then you can crow as you please.
My ability to crow is unaffected by my pocketbook.
I do thank you for your misplaced concern for my welfare.
I'd rather donate $50 to find out why you can be so insulting to some and it is considered furthering the CNC craft?

Wasn't the issue you have with me about politics?
I've let it go.
Will you reciprocate?

[michael_schwartz]

I guess the challenge would be machining the table on a 3 axis machine, but my guess would be that it could be done with some jigs, and spacial thinking. The design is very elegant.

[gc3]

white out is proprietary info

[myxpykalix]

Gene,
I'm not sure what i'm looking at possibly some type of jig in the small parts of the pic. With an indexer we could chuck the part up and then rotate (X) degrees for each part or side.

Well rather then trying to figure out some type of jig that you have to make a negitive of the part for it to sit in in order to machine the opposite side why not have something that will hold the part between 2 centers with a indexing wheel with a pin stop at your 90 degrees (or whatever angle) you need. Assuming you don't have an indexer this allows you to move your angle without having to make a supporting jig.

[michael_schwartz]

I have thought about setting up a manual indexer for making chair parts. Although at that point you might as well just add a stepper motor.

[myxpykalix]

If what you are trying to make is symetrical legs or things like balusters then you could mount a lathe which would just spin your material then use an indexer virtual tool to cut a dxf profile. But as you say you could just add a stepper motor and as some people have posted some fairly inexpensive indexer setups.

[fabrun]

one question:
what is the maximum tool length you can use on a bot?
flatmil and ballmil (3mm diameter)
thanks

[myxpykalix]

I think the answer to that depends on the type of material you are cutting. I have seen some fairly long (6"+) bits used to carve foam but for wood i think the flexing would cause problems. Most of my longest 1/2" shank bits don't exceed 3". I do have some side reeding bits that are 6" or more but they are a light cut type bit.

Jim can tell you.

Hand is 75% normal function. Thanks Chuck.

Gene,
Your hand functions 17% better than my brain!
If I read between the lines after viewing your link, you've suggested quite a bit.
The fella that built the camel this holiday season built a beautiful 3D model with a 2.5D machine. A prime example.

The catch is creating "the slice" with all positive draft....or at least minimizing negative draft and within the limits of the cutter bit and the Z.
Creating a negative or positive well to support the part is commonly done in 3D printing.

BTW...Your creative and effective use of white-out blows away the competition.
;-)

[gc3]

something to do on a sunday

not to change the subject.....

so Chuck, you in for the drawing or what?

Gene

[fabrun]

how about slicing like this ?

[navigator7]

how about slicing like this ?
You are on to something, Fabrun.
The guy that did the foam camels did the same thing but he inserted a register or berm or a locating method so each part fit tightly into the next.

Can your program create parting lines or show you where there is negative draft?

I envision adding excess material at the top and bottom of your part to not only be of use for locating but also for clamping or fixturing the part securely and precisely. The extra would be removed by a bandsaw or Fein tool or what have you one all the work was accomplished.

Also, machining a negative or positive fixture that your blank would be inserted into during machining. It could be as simple as a sheet of birch plywood with its own set of location system so set up time would be minimal.

Notes of feed, speed and 'lessons learned' during prototyping could be v-carved into your fixture making the valuable fixture less likely to scraped between projects.




@ Gene,
What drawing?

[myxpykalix]

Gene are those "sour grapes"? lol I love them, did you draw them up yourself? That looks kind of like cedar is it? Was this part of a different project or just practice? excellent job. Thats what i like about these machines they make us look like artists.

[navigator7]

..... excellent job! Thats what i like about these machines they make us look like artists.

There is a lady nearby who makes boxes and decorates them....and sells a few. They are very nice, well done and extremely mundane. Gals should love em.
I'll put all of her boxes up against Mike's "brainbox" for sheer novelty, pleasurable viewing and utility.

She said: "I'll never have any of those CNC machine made boxes 'cause anybody can do that!" I swear she spit something on me telling this.

The same logic can be used for the steam engine vs a gas engine, the microwave versus a camp stove and 8 track cassettes vs and Apple Puter.

Star Trek inspired engineers to give us doors that open upon our presence.
Its well on it's way to inspiring 'Replicators' for the home.

I see the day when you need an extra plate for a house guest and you speak into a box and call out the guest plate file and presto!

If a customer says he wants 'grapes' on his cabinet door or project xyz....and a guy like Gene satisfies the customer is a day or two....That is Art!

I went to an art show this weekend. A guy was selling a hand carved Alfred E. Nueman. It looked hand carved and reminded me of a musician missing a note. It would have been so much better with cnc and a little creative license.

I humbly reject your notion with much mirth, Jack, that these machines make people look like artists. They are artists!

With my gun I might hit a target. Jed Clampett made a million with his gun. It's not what you got but what you do with what you got!

A photo a client sent. Sample cut 4"x8"x.520". Will be used in a exterior door panel, plus a kitchen sink valance. Wood is makore, straight from machine no clean up. I am no artist, simply a shop owner trying to add a new dimension to the products we produce.

[myxpykalix]

Is that wood indiginous(?) to where you live Gene? It looks like it is a nice wood to carve with. Does it smell? One thing I have heard about exotic or tropical woods is that some species are more toxic (thats not the right word) then our domestic species and i wonder if that is just because we are not used to it and would it be toxic to the natives of where it came from?
That sounds like a question Alfred would want to know...what me worry?

[fabrun]

Can your program create parting lines or show you where there is negative draft? yes chuck, my program can do that

some improvement

Makore, African Cherry. Carves crazy well no hand work is needed after cnc only draw back is that it has a high silcia content so.....bits are done after a 1 time cut. I got lucky and found a listing on woodweb www.woodwec.com (http://www.woodwec.com) for 500BF of this for $2dlls a BF so I bought it. Shipping and delivery to us here in Los Cabos final cost $5 per BF. We get most of our exotics from here www.bozovich.com (http://www.bozovich.com)
