Title: CNC Lathe's
Post by: Hawklore on August 14, 2005, 02:32:43 PM
How do they work?

What kinda programing do you need to know to make it?

Where can I get one that can make bowls/plates/eggs

You can get one from here for $8000, http://www.microkinetics.com/lathe1236/

You first have to draft the peice(CAD) and then convert it to x,y,z for the lathe. Sometimes the CAD program will do it for you.

You are looking at big $$$.

and, from the sounds of it, a heck of a lot less fun than simply doing it the "old" way

Well, I guess since i'm going to be creating the same item over and over again, just figure out the dimensions and do it by hand..

I made some wooden eggs, but the omlettes came out all splintery.

Didn't scramble enough, and you gotta use the right kinda cheese, if you use hard chedder it kinda hinds that splintery look/feel.

CNC machines are expensive, but are incredible.  The only one I've worked with  came with its own software, so I don't know if you'd buy that separate or not. Anyways, what you do is you go in and design what you want.  The one I used could only cut into flat wood like a 2x4 or something like it.

But, you'd go in and design something, set different cutting depths if you wanted.  Then, you could set what tool you'd be using, such as a ball end or flat end.  You'd then send it to the CNC/Lathe and it would write the program necessary to make the proper cuts.

Hit go and it would cut.

But, as said before, you're talking BIG bucks if you plan on getting one, especially if you want to make bowls and the such.  You're also talking about lots of time, effort, and wood to do stuff.

I don't plan on making bowls, it'd be nice..

I plan on making eggs basicly..

wooden hand grenade replicas, etc.. minus the spoon..

You're talking a good $5000 to get started for anything that will be able to make that. You'd be better off whittling them out.

Why would you want to make replicas of wooden hand grenades?

make your own lathe for woodworking.
CNC lathes are mainly for high production metalworking.


http://www.historicgames.com/lathes/treadle.html

http://www.historicgames.com/lathes/ancientlathes.html

more links on either of those pages to show more lathes.
have fun. :)

edit; btw check out ebay, some woodworking lathes are listed for sale there too.  seen one for around $100 on there.

:o

Wouldn't you like to have a nice wooden grenade that you could pack some powder in, light a fuse, throw at someone, and not have it actually do damage?

:aok

CAD CAM transfers the NC moves into APT. Then a post processor turns that into MCD language.  With CNC, I believe the software will do both, but your Cad portion is "what you pay for is what you get"  The more $$, the better the CAD CAM on the CNC is.

So it's basicly like hookers, electronics, and food.

Why reinvent the wheel?

Just buy some of these, paint them if you have to do so.

WWII Russian Grenades (http://www.armorcast.com/grenades/)

All grenades are made of solid polyurethane rubber and are molded from original grenades except as noted. Grenades are supplied in "as thrown" condition as shown in the photos - no spoons or pins are provided.


(http://www.armorcast.com/grenades/picture/ACRDG33.jpg)

Russian "egg shaped" grenades $13 each.

Stick grenades $24 each.

Unless you just like to whittle a lot, of course.

Ohmygod! :D

We had "professional education" day every week in Soviet school starting in 8th grade, there was a CNC lathe operator class, but I have chosen a useless "Electronic Calculating Machine Operator" class, I have a diploma of IBM/360 series operator (EC-EVM), it never helped me, no perforated cards around here :(

If I was a CNC operator I could make enormous money now, but OTOH I had to really work instead of posting here ;)

I do 3d modeling, CAD, CAM and CNC stuff on an almost daily basis.

This is the big machine I get to play with at a company called Cybershapes where they normally do surboards and such.

You can see more from that project here: http://www.easyracers.com/pod/web/

Check out Solidworks and Surfcam as the defacto standards for design and machining.

Not sure what ripsnort was talking about.

You use CAD (Computer Aided Design) software to design your stuff. AutoCAD, Solidworks, even programs like Rhino3D.

You use CAM (Computer Aided Machining) to generate "G-Code" which is the common language ALL CNC machines use for their directions. Some CNC machines only support some "G-Code" or have their own proprietary languages. Most CNC machines come with a "post-code" that plugs-in to your CAM software that tells it how to properly implement the g-code for that particular machine.

Once you get everything set up and running properly it's incredibley powerfull and relatively easy. I watched a machinist with 25 years of experience practically break down and cry when a relatively new machinist/computer geek (me) started making parts that he simply never could.

I can draw up a relatively simple part, generate the g-code and be cutting the part in less than 15 minutes.

Don't think he's in buisness anymore, and isn't exactly cheap..

CNC/lathe = about $2000 to get started
grenade, made already = $13

hmm...?

If he's not in business anymore, call him and buy his molds. Way cheaper than a CNC machine.

JACKSONVILLE - Tragedy at a WW2 re-inactment today claimed 53 people. " It was supposed to be all in good fun!" shouted a man dressed as a German soldier on a stretcher as he was put in an ambulance. The noonday massacre claimed 53 lives and wounded 270 others, including a duck. The waterfowl is expected however to make a full recovery. Witnesses say the Russian side proceeded to throw wooden grenades at anything that moved. Ironically it was the Russian reinactors that bore the brunt of the losses.

Hey g00b, is that "DO NOT HUMP" sign there for your benefit?
