Abstract

The main objective of this project is to develop and establish of marking procedure and investigation of marking characteristics of most commonly used EN8 Bearing steel for ball bearings. To perform the experiment, an experimental design matrix was constituted using the design of the experiments. For this purpose, in the Response Surface method, Box Behnken design was chosen as a statistical tool to build an experimental layout and also for the Optimization Response Surface Method. An Nd-YAG laser and Fiber laser was used in the laser marking process of stainless steel. The influence of the pulse frequency, Focal Point, marking seed of the laser beam on the mark depth, width and mark contrast have been studied in this Dissertation. Design of Experiment was obtained using Box Behnken design. Also Anova and Regresion Analysis were performed. Optimization of that parameters has been done using Response Surface Method.
