Hello Khan:
Welcome to robot-forum
You're in the right place, there are simulation guys in this forum and also "router" guys
My first thoughts after reading your post were:
Router: he needs a heavy duty robot, over 100 kg payload
Size of parts: he needs a couple of robots at least for those fixture sizes unless the fixture moves
0.015": Ok, 0,010" and better, well he's pushing it
Any robot manufacturer in particular ?
