Laser Cutting
Week 2 For the 2nd lesson of CPDD, we will be mainly talking about The Learning objectives of Week 2’s lesson Introduction to laser cutting Reflection on Week 2’s lesson Learning objectives The learning objectives of week 2 lesson is to Explain how a CO2 laser cutter machine work Describe the hazard and safety associated with the operation of laser cutter machine List the materials that can be laser cut in FabLab SP Explain the difference between raster and vector Explain kerf and its impact in laser cutting Introduction to laser cutting How does a CO2 laser cutter work? A CO2 laser is produced in a sealed glass tube mainly filled with CO2 and some nitrogen. High voltage electricity is passed through the tubes which increases the energy of the gas particles and produces an invisible beam of high power infrared light(laser beam). In order to move the laser in different directions, there are multiple mirrors that reflect the laser that exits at the end of the tube to the focusing lens a
