Last year finished an all electric tube bender. Using 2 parallel ports for it's 6 axes AC servos. The machine has 3 die positions and a wizard for creation of g-codes from L-R-A data for pipe bends. AC servo motors are used for all the axes movements as well as bending stroke, wiper die and pipe positioning for die change. Recently uploaded it's video on youtube. Here's the link http://www.youtube.com/watch?v=tLw6qhW3wlA

Excellent. I could watch that working all day long. 

(I think we would need to have a lot of guards around a machine like that under our health and safety legislation).

Thank you Tweakie for the compliments. Unfortunately we don't have any such legislation here. Some multinational companies encourage you to follow safety guidelines though. I try to make my machines as safe as possible. The video is of very first trial run. For production runs we've installed many safety guards on the machine.
