5 Axis MM Conversion Discussion

After you asked your question, Darren, I've been thinking of how a 5 axis machine can be made. Whew! The conception of a 3 axis is easy comparatively speaking. I guess the start point would be to find software that can handle 5 axis then figure out how it handles the additional 2. For another day...

5 axis software is super expensive. So you'd better find the affordable full 5-axis software and then build the machine. The machine is the 'easy' part. CNC zone has some cool 5-axis examples. http://www.cnczone.com/forums/diy-cn...new-build.html

Zero aspirations for a 5 axis here.

If you have $10,000 USD you can play with the software that is needed for it to work effectively. Rhinocam has Visualmill with 5 axis continuous machining.

Didn't say it would be cheap, or easy, but the concepts are cool. There must be a hundred or more ways to make one workable. Pete, surely they have a free demo or something...

That is just the software. To make 5 axis work effectively, continuous machining is the way. Everything works in harmony. You can go indexed machining but not worth it in the long run. Rhinocam is well spoken of, however I never used it.

I think they're around $2000/axis.

Someone else can be the pioneer on the 5 axis setup.
I nominate Tom Ayres.....
Do I hear a second???

Ok, Ok, I'll 'look' in to it...After watching the video of the DoughtyDrive B/C axis assembly, way cool by-the-way, there would have to be a major y-car change and the height would have to be at least 3 times taller than what we have as a standard to be effective. The spindle would have to be air cooled (I don't think a water line would survive all that flex). And then there's the issue of Z flex. Crazy changes to make work. It does give me ideas for modifying their concept though. I'd have to start a thread on cnczone, not going to happen any time soon...

Any one of you machinist guys interested in fabricating a few parts if I can design something reasonable?

How does one zero 5 axis? "How many licks does it take to get to the center of a tootsie roll tootsie pop?"

I have seen videos where they have machined an aluminum box and they touched off with a probe to zero to all five sides of the box first then started the machining process.

No war, Heath.
I'm intrigued but will admit it is way past my skill level.

Well there will be no 5 axis using the b/c drive, cost is $2950 + Freight plus another $945 + freight for a 2hp (1.5kw chinese) spindle. Ha Ha, LOL. the drive uses 300 in/oz steppers that can't be changed, claim zero backlash.

That's not terrible pricing if you needed to start a 5 axis machine.
