double sided cnc


Me and a group of guys are trying to make a multi axis double sided cnc machine that is capable of double sided friction stir welding and incremental sheet forming.
It is more of a proof of concept rather than it has to work fully as we understand that this is highly unlikely considering our current experience. Some of the requirements include high radial and axial forces.
We would like to get some information regarding:

Whether a raspberry pi with I/C expanders would be enough to control the synchronization of the two tools?
How would we go about the programming when two tools need to be synchronized?
Any ideas on possible structures, we have considered using steel frames and strong dovetails.
How we can tailor the machine design to deal with the huge axial and radial forces it would have to withstand?

Any kind of reply is much appreciated, even if you don't know the answer, anyone with any kind of cnc machine design experience, your help, experience and expertise would be much appreciated.

Travis, this forum is narrowly focused on building and supporting the MechMate design.

Generally the first question we ask here is "Are you building a MechMate?" ... it it seems the answer to that is unlikely to be yes.

You may have better luck asking over at cnczone. Seems like an ambitious project. I would suggest that you investigate similar existing designs to find a mechanical structure that works.
