Hello! I have a problem with cutting thin (0,5 mm) metal sheet on waterjet - it creates a sharp barb (sorry, I do not know correct word in English) on the bottom side of the cut all along the cut path. I have seen this only on thin metals. For 3 mm thick metal bottom side is fine and beautiful.
The thing is that these parts have to be placed atop on each other in blocks of 200 parts and even more, so the bottom side has to be smooth. Currently they are cutting those parts by hand, but they want to reduce the amount of hand labor. Laser and plasma have been rejected as they burn off the protective coating on material, but test cuts on waterjet have that sharp barb on the bottom that I have seen also in other cases, when I was cutting sheets of thin metal. I know that some LinuxCNC users have experience with waterjets. Can anyone suggest me something to fix that? Is it depending on garment size of abrasive? Slower feedrates have already been tried. -- Viesturs If you can't fix it, you don't own it. http://www.ifixit.com/Manifesto ------------------------------------------------------------------------------ Everyone hates slow websites.
