Laser cutting of Aluminium alloy BS 1100 sheet using CO2 laser

The problem under focus for this research work was gas laser cutting of ―difficult-to-laser-cut‖ material. Non ferrous materials such as aluminium alloys, brass and copper alloys were the difficult-to-laser cut materials. They were named so since they were less absorptive to laser beam by nature and reflected majority of the laser beam that falls upon them. Hence laser cutting of such material became a tedious task subject to various limitations such as sheet thickness, higher kerf width and higher surface roughness.
