On a related topic, here's a scary video of a tubing bender.[1] This is an example of something that's automated just enough to be out of human control, but not enough to be safely keep the operator out of the workspace. Note the operator being hit by the end of the tube at 00:45. If that job had called for more bend, he would have been impaled. OSHA lists 85 bending machine injuries, usually involving finger amputation.[2] Bending machines are unusually hazardous because the workpiece can move way outside the machine's own boundary.

Don't design stuff like that. Either put the process under continuous operator control, or get the operator clear of the moving parts.
