International Journal of Engineering Trends and Technology (IJETT) – Volume 6 Number 5- Dec 2013 Material Processing by Laser: A Review Vijay Narayana* Nitesh Guptab S.M Farhanb a:Department of Physics S.R.M.G.P.C.Lucknow b:Department of Mechanical S.R.M.G.P.C.Lucknow Abstract:-This work investigates the application of the CO2 high power laser emphasised with the help of computer, laser Nd-YAG cutting processes examined were in at the materials to be cut by laser. The material then different thicknesses ranging from 2 to 10 mm. The process burns, melts or is blown away by a jet of gas impact, parameters were examined as:- leaving an edge with a high-quality good surface finish. Laser cuttings are mainly concerned with industrial o Laser power application such as cutting, drilling boring of any solid o Range of cutting state article. [3] o Speed II. TYPES OF LASER CUTTING: o Type of focusing lens o Pressure and flow of the covering gas o Thickness of the samples Index terms:-Types of laser cutting, process of cutting, finishing and tolerance. I. INTRODUCTION After the discovery of first solid state laser ( ruby laser) “used for drilling boring for diamond dies in engineering research centres. In
