double sided fsw and isf

[freddi]

Hello MyCNCUK,

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.
