A Review on Parametric Optimization of Laser Engraving using Fiber Laser on Steel

This Review Paper describes effects of laser Engraving on various materials by varying process parameters and by using different laser engraving machines. Laser Engraving is a non-conventional machining process for engraving/marking and it is a non-contact type process. Previously where only Electrical Discharge Machines were used, laser engraving and marking have replaced them due to a unique combination of speed and versatility. In Laser Engraving process material removal is done layer by layer and which is in the range of very few microns. This Review paper shows progress and research in the field of laser engraving process. Different types of laser machines such as Fiber Laser, CO2 laser, Nd: YAG Lasers are industrially used & available in recent time. Therefore for Optimum Use of Laser energy it is necessary to optimize process parameters to get best Quality Engraving/Markings. This paper deals with important progress work on laser engraving and its process parameters.
