Laser cutting
LASER CUTTING For this week we did laser cutting and the objectives were to: explain how the laser cutter works the risks and hazards that comes with using a laser cutter name the materials that can be cut and how deep it can be cut explain the difference between raster and vector So how does a laser cutter work? Specifically a CO2 laser cutter since that is the one we'll be using. It works by passing high voltage current through the tubes mainly filled with CO2 and some nitrogen which would increase the energy of the gas particles and produce an invisible beam of high power infrared light(laser beam). To move and redirect the laser beam, multiple mirrors would be use to reflect the laser beam to the focusing lens and onto the workpiece. The purpose of the focusing lens is to focus the beam into a small point making it more powerful like a magnifying glass. If the focusing lens is damaged or is too close or far from the focal point, the laser would not be able to cut ...
