Hello
Would there be an annotation rule to signify the face of a sheet metal part that must have the surface protected?
Thank you and have a good end of the afternoon
With us and all the laserists we work with, they cut on the film side, so the surface is protected on the top.
Edit: if I'm not mistaken, it's the gas that cuts the top protective film and not the laser.
Film underneath, the film would melt way too much and stick to the sheet metal.

No rule to my knowledge, we are satisfied with a note "protected face" or "face visible" depending on the customer and the use (and the wind speed and the speed of the lightning, or even the mood of the day).
