Laser Cutting Sheet Metal
Laser Cutting Sheet Metal
(OP)
We laser cut various size parts from HR sheet metal. The problem we are having is when removing small parts form a cut sheet. We have to tab the parts (.020 - .040) to keep them from tipping up and causing the torch head to crash. However, this causes a safety issue when the operator has to shake the cut sheet to get the parts to drop out, sometimes having to tap them with a hammer. I am trying to find a system that will get the parts out without the operator having to continually shake cut sheets and exposing himself to shoulder injury. Any advice would be appreciated.

Is the problem due to the heat all on one side at the end of the cut causing it to rise? Could you leave the tabs in for the main cut to prevent it from tipping and then go back and cut out the tabs with the laser?

I've found that the thicker the part, the smaller the tab, although that frequently raises other problems.
Can you grain-constrain your parts? If they're long enough to span 3 slats, then they may not tip even if you don't tab them.
