Re: [CAD_CAM_EDM_DRO]doodling with ideas

Bill,
The machine you describe is similar to an overarm router. They were used in the "old days" by the aircraft industry to rout stacks
of aluminum sheets from templates.
Yes you could get it to work, the only problem would be the software. You might have to write your own to translate x,y into dual
radial elements. Robotic arms (welders, etc.) work on this principal, so there may be software already available.
EMC might be able to do it.
However, I question your reasoning. Unless you just like doing it the hard way.
