It was verified that the values recommended by the equipment manufacturer can be optimized, being possible to use less radiation power in the laser beam with greater speed of cut, providing a better cut surface quality, improving and optimizing the entire process. Through the Taguchi statistical analysis model, it is possible to indicate the best set of laser cutting parameters. Metallographic and cut surface analysis, burr and roughness measurements were carried out, supported by a Scanning Electron Microscopy and profilometry. The different values were performed cutting a stainless steel AISI 316L and a cold rolled steel St12. Three important laser cutting parameters were studied in order to investigate their importance in the cut surface quality: radiation power, cutting speed and gas pressure. ![]() ![]() Thus, this study is aimed to improve and optimize this process using a fibre laser equipment. ![]() This loss of quality is usually related to a burr problem. The machine is supplied complete with SOFTWARE, easy and intuitive, capable of importing files from the most well-known computer-design programs currently in. The mismatching of these parameters leads to a loss of cut surface quality, which is hardly re-established. One of the main problems with laser cutting equipment is related to the wrong setting of cutting parameters.
