I didn't know where to put this so I though here would fit the best.
does anyone here have any experience with 5 axis. I am primarily interested in the 4th and 5th axis at the moment and in particular which design is best for stiffness. I am not even sure of the proper names but I think it is trunnion (sp) and yoke. What type of system is used to give them their movements. I have seen pics of them that appears to not have a motor on them at all. If someone here has design their own 5 axis from scratch without using the sat units I would appreciate any input.
