That work on a sphere?

Michael:
Cabling is now becoming a major issue as the 4th axis is introducing another cable. It's as simple as an investment into those cool cable carrier systems. $500 and it looks like a million bucks. The next and final stage is the 5th axis. That will allow full access for the cutting tool to the material in any angle. Dust collection is working perfectly. I just finished 17 Stair treads which had a very complex nose and back. I made the profile with MOI and used Rhino to create the tool path. Projecting the curves and creating the surfaces somehow was easier with MoI then with Rhino. I use MoI as my Swiss Army Knife and then Rhino for the confabulated and strange modeling tasks which justify the time spend with the slightly awkward Rhino Interface. Awkward because it's stuffed with goodies and thus a tick overwhelming. I use multiple programs and all the power programs like ZBrush or Rhino which have great 'depth' in regards to functionality are not necessarily my friends as it takes a lot of exercise to stay current with their work flow. MoI and Cinema 4D are great examples of complex applications which present the functions in a rather intuitive and easily accessible way.

Pilou: That will be possible with the last of my enhancements which is the 5th axis. That will turn the cutting spindle itself and thus allow the perpendicular orientation of the cutting tool to the material surface in any orientation. The 4th axis as it is allows more freedom already but still has minor limitations. Right now I can create a sphere, but projecting an engraving path on it is limited to an orthographic 2.5d method. If I keep the engraving flat, I can create pretty cool results on a sphere as long as I stay away form the poles. I have the plans ready for the 5th axis and the software as well. Only the money is missing... The 4th axis has to earn the money for the 5th. As did the three axis earn the money for the 4th. Unlike the US financial system, this machine has to earn it's keep.

I'll keep you updated. I plan to cut some real exciting stuff on the weekend.

PS: Any chance for a cool surface following wrap tool Michael? ;}

I have seen that exist 13 axes!
;)

Hey Pilou, not the pipe bender again ? ;)
You need 13 axis if your bending pipes, maybe you should get yourself one.

Cheers

Hi Rainer,
What software are you considering. If toolpath from rhino, sounds like VisualMill?

I use RhinoCam V2. The big brother of Visual Mill. VM does not have the full set of modeling capabilities. So Rhino and RhinoCam is pretty feisty combo. Add MoI and making stuff is only limited by the imagination. And the size of the wallet... Vectric also has nice software but all the software including 4th and more axis support are in the $3000 upward region.

Hi Rainer, it will be cool to see the 5th axis added as well!

> PS: Any chance for a cool surface following wrap tool Michael? ;}

Yeah, this should be possible at some point, but I think probably won't fit in for v2 though.

Are you talking about a tool that would take 2D planar curves and then map them to follow a surface? That particular thing is not as difficult as trying to morph a whole solid to flow along a surface, so it will probably be able to happen sooner than solid deformations. But I don't think that it will get squeezed in for v2 though.

Nice! No hurry. But a nice prospect.
If you send me a model I'll mill you a foot tall MOI in Wood.

Hi Rainer,

Wow, that would be cool! Unfortunately I don't happen to actually have a model of that statue guy...

Maybe a hint to the community...
I'll launch a contest 8)

Here is what I routed with my machine and my new axis last night:



Design in MoI of course...

Wow! beautiful Lemo.
What timber did you use, some sort of ash and what is the size of the sculpture.

Cheers

'Tis a thing of rare beauty!

That's a beautiful model! thanks for sharing

Hypercube :)

Beautiful!
Quite amazing that you could do that in one piece, it looks pretty big.

Wow, what a fabulous result!!!

This totally looks like an art show piece. Do you have any plans to make a collection of these for a showing or for sale?

Really great joins too, it is hard to see them without a very close inspection.

That's a really beautiful and rather unexpected form to come out from CNC, I really like it a lot.

I would like to see some screenshots of the camming toolpath and how you did that without a trunion table.

We have a rotatry also and am interested in your technique. We are limited in our software as we can only wrap and index, and I know you said you have RhinoCam, probably with 4th axis capability??

Anyway, Very nice! Anyinfo you could post on the CNC side would be valuable and appreciated for and by me!

I suppose this thread took a break until April 1 for a reason.

Sure hope that's not an April Fool's...
