oh man, what he is doing is nothing compared to what its capable of, It could do a profile of your face 3d and all. no rotary tables needed. with rotary tables you can machine some really crazy stuff too, all the way around parts, on 4 sides or whatever, really cool stuff. and with 2 rotary tables
now thats some insane stuff, thats where you get to the 5 axis machines. maybe someday
I did see a 5 axis taig.............
yeah, what he did with that thing is some very basic cnc opperations, G1 linear interpolation, G2/3 would make the curves I bet that thing only uses those codes and G0(Rapids) lets just say theres Gs up over 100
Heres some cnc stuff of mine:
