I may soon have the opportunity to purchase an ABB IRB3000 6-axis robotic arm REAL cheap, much cheaper than building a quality cnc mill. My question is can a router be mounted on something like this and be used to create anything that I would on a cnc machine? Repeatabilty is .002". Is this accurate enough? Is this worth trying or a waste of time and money? I think the programming could be a catch, because there isnt much aftermarket software for these. Are there other reason that a robotic arm isnt used instead of a cnc machine?
Thanks all.
