Production and minerals engineering department at the Technology University grants MSC to the student Zainab Jabar for her thesis "Influence of Laser Beam Parameters on Hole Accuracy"

The purpose of this thesis is to study and analyze the effect of the force (600,700,900,1000) W with Cutting speed of (2.2.5,3,3.5,4) mm / min and  gas pressure (2,3,4,5,6) in term of using fixed factors with different diameters on the accuracy of the hole. The results of optimization of the surface response methodology showed that the expected value corresponds to the experimental values in a well and reasonable manner for the accuracy of the hole (95.96%). The results showed that the depth of the heat effect area increases with the visit of the parameters (energy, Gas) while the hardness of the metal decreases with increased factors.
