Blue leather with 3-mm thickness was marked and cut by a 10 watt CW CO2 laser with a 3.75-inch focal length lens. The speed of 50 mm/sec was used for etching surface with one pass and the speed of 10 mm/sec was set for cutting through the sheet with three passes. Total cycle time for cutting and marking the whole part took 6 min 40 sec. For reducing the cycle time, the higher power CO2 laser was recommended to be used in the application.
