When working with new materials there is always a question of where to start in regards to settings with your laser cutter or engraving. Since the laser cuts in a thin conical shape, more power will result in more perpendicular walls and a deeper cut, but will also mean more material removed. Our test file engraves a series of squares, all at a speed of 200 mm/s, and varying power levels all the way up to the maximum allowed power of 85. The differences in the operating cost are based on the maintenance and the efficiency of the style of laser being used. The final piece of the puzzle for laser processing is the cutting speed. 120w – 90% speed. 240. on Introduction, Awesome idea! Find the square that you like the most and use those settings! Once you have modified the artwork to your liking, it's time to engrave. Is there a printed chart on a page or website that can be used as a guideline regarding cutting/engraving speeds/power to use for different products (glass, cork, leather, etc.). In fact, the laser etching elevation can reach up to 80 microns whereas the laser engraving depth can reach 500 microns. So we need to turn down the speed a bit to ensure we get through our material. Why do all test cuts use max power of 85, instead of varying power? 40w – 30% speed. As power increases, the energy in the laser increases. Less time = less cost. 13837 0 obj <> endobj Reply With an increase in speed, the less time it will take to finish your project and less time = less cost.
