I have had titanium and steel sheet cut with a laser and am somewhat
familiar with the process. Did they give you a cost per inch of cut?
The kerf width varies with the thickness of the sheet, the thicker
the sheet the wider the kerf. Most of the metal will either end up in
the water tank below the laser table or deposited on the surfaces in
and around the machine. My understanding is there is a gas nozzle on
the cutting head that blows the molten metal and vapor out of the cut
line where the laser has melted it otherwise the metal vapor would
block and diffuse the laser beam impeding its ability to cut.
