I'm stuck here. I need to cut pieces from spiral wire. I have the system all figured out, but I'm stuck with the cutter section. The wire itself is steel, about 1mm thick, but the spiral diameter is about 2cm. So the blades have to move minimum 2cm to get out of the way after each cut to allow the system to feed another length of wire. The cutter should be able to cut about 1 cut per second.
Have been thinking hydraulics, electromagnets, motors with excentrics etc. But still don't have a solid and working idea.
Hydraulics is usually too slow, electromagnets too weak and with motors, which seem the best solution, there is the problem with percision. e.g. stopping exactly after one turn. steppers aren't powerful enough and DC motors would need a brake of some kind...
Any ideas?
