![]() Carrying out test cuts on different materials and filling in the data into a record sheet.Repeating with the other lenses available.Running the power test program (available here) and establishing the available power.Defocusing the lens to reduce the energy density and prevent etching its anodised aluminium surface.Using a power meter to measure the available power of the laser (See Video 11).Checking the resulting size of the test square.Potentially adding an example on the sheet.Filling in your parameter table including:.Air assist should be minimised on organic matter.Using a small pot of water to get a visible indication of the air assist rate.On card in the example the edge was sooty so we increase double the speed and try again – use an iterative process to find the best speed. On card in the example, if there is smoke you know you haven’t cut through. Place the job above the bed on something (Russ uses ‘dome’ nuts as stand-offs).Process for determining the required cutting parameters:.MIA (Perhaps included cutting laser board and not using air assist?) The Process to Determine your Own CO2 Laser Cutting Parameters.Percentage power best measured with a power meter. ![]() cutting, making lines, dotting mode, scanning (various types). Parameters needed for different type of work, e.g.Cutting parameters – documents yet to be made available.How to derive your own CO2 laser cutting parameters Contents
