Anyone Convert A Mini-Lathe To CNC?

[Macklin]

Next year I'd like to convert my mini-lathe to CNC. I figure I should start preparing now. So I did some research on the sublect.

I found several versions of plans to convert to CNC, not sure which to go with. I also found plenty of sources for controllers, motors and computer software, but nothing that tells how to make it all work together. I'm assuming this information is covered in at least some of the conversion plans?

Anyway, I'm just looking for some additional research material, preferably something that goes in-depth as to how all of this is done. The forums and websites found on Google aren't really geared for the novice.

Clown--read the above site, it's all there.

For CNC conversions also see the Yahoo groups on mini-lathes, etc.

Harbor Freight and Grizzly tools. Check out the link above for others

Harbor Freight's a last resort for these. I got mine from Homier back when they were getting some extra-nice ones, but so long as the price hasn't gone up that's probably still the way to go.

An other thing to consider is you will likely need to learn to use some sort of CAD program such as Autocad that can convert your drawings into G code(that's what the the CNC software uses). I have contemplated converting my mini-mill and lathe to CNC but loath the idea of having to become competent with CAD software(took CAD in college a long time ago and didn't really care for it back then).

For CNC info, head on over to cnczone.com. They have a very good forum section and you will find tons of information. Converting your machine is only part of the battle. You will also need software. First, you will need a program to draw your part in. AutoCAD is OK, but with today's machining demands, a 3D design program is better. Since you will probably only be doing small round parts, AutoCAD might be enough for you. Next, you will need a program to convert the drawing file to G code. I suppose you could just hand write the code yourself, but you would then need to learn to program in G code. These CAM programs are not cheap. A good entry level CAM will run you about 2 grand. You will also need controller software to feed the G code into to translate to a code your machine can use to move. Mach 3 is the best low end program for this.

I've been using Rhino 3D for about a year now, designing various parts. I understand they have a nice CAM plugin available.

I think where I get lost is the whole controller software/hardware issue. I've found plenty of vendor sites and forums on the sublect, but everyone discusses who discusses this stuff already knows what they're talking about. I get lost in the chatter and technobabble. LOL It'd be nice if there were a mini-lathe.com for CNC beginners.

Oh, well. I'll keep researching. Thanks for the input, guys.
