Setting up a Turntable with Grasshopper and KUKA - Part 1

Hi Karl ! many thanks 4 your comments and sugs.

Hard to get to get 2 kukas around here but contracting the job outside could be a fair option so I'm certainly very  interested in a definition for the option you mentioned.

An important thing to account are materials related with the options we are presently considering as alternatives to generate the molds: ie lattices & shells and/or EPS or similar milling / cutting, in the sense that the latter probably could be performed by a much lighter (cheaper), and eventually longer reach (desirable) robot, eventually in combination with other machines.

Least but not last, in the case of cutting, but specially in the milling approach, i find key the way the paths are defined so as to be as much efficient (fast) as possible - obviously related with final quality. In that particular case i have some experience using my cnc with curved hot wires for cutting... and also thought about quite a lot non standard milling bits that could be used and i would like to explore. (ie a "big ballnose") despite i don't have nor know about the existance of such things.. yet :).

So just in case you might be interested or can help with any comment or sug. is welcome in advance.

Many thanks !

Franco, I'd separate the code in two and manually rotate the material instead of relying on a single piece of machinery. If you're working with such large scale pieces, and you can afford it, two kuka's would be perfect.

Hi Carl, great vid. Thanks for sharing. I couldn't complete it because i ended noticing the lack of the kukaprc2 full ver but was totally illustrative of the core concepts. Thanks !.

I own a 3/4 axis CNC table for some time now and used it to machine many kinds of stuff mainly by cutting or milling EPS. I also did some tests with a self designed rotary head that uses a circular saw blade (this one i mention for your video about the saw blade setup (v. cool too !)).

So I was wondering if you have had experiences in machining forms like the one I attach below.

I'm interested in all possible ways to use CNC techs to actually build positive or negative molds for parts like the one in the attached pic.

Thing is that sizes that sometimes i have to deal with, can't be fitted (without prior splitting) neither in my (2.5 x 1.3 x 0.2 m) CNC table, nor even in the envelope of the basic setups of typical robotic arms - even the biggest ones - like the r2500 i ended up testing with GH (in the attached pic)

So would be great to hear from you in case you have suggestions, ideas, or even a project we can work together. feel free to email franco.ferreiro@gmail.com
