Cut quality of mild Steel by CO2 laser

Abstract

Cut quality of mild steel by Co2 laser is studied extensively and new approach to classify quality is presented . This approach is based on combining different parameters such as cut kerf, heat affected zone and roughness.A mathematical relationship(in matrix form ) has been developed to include all the above Parameters in one factor which is called the quality factor . In addition , cut quality by CO2 laser is compared with many different machining techniques which are produced by previous researchers .This comparison shows that CO2 laser are an excellent tool
