STUDYING ROUGHNESS OF STEEL CUTTING PROCESS BY LASER

Abstract

ABSTRACT: Practical work on laser – Steel cutting Process for thin sheet to gain better informations on cut quality .Relationship between cutting speed and roughness of the surface at different pressures is shown . It was found that the smoothness of the cut Process is proportional with the cutting speed without any apparent limitation . Roughest is also Proportional with Pressure of the oxygen gas which is used with CO2 laser beam.Keywords: "Roughness , Steel , Cutting , Laser".
