Abstract

This paper describes a variety of fundamental research of laser engraving of different materials which the authors have recently performed. Laser engraving is machining process where material is engraved by laser process. In this review the research and progress in laser engraving of different materials are critically reviewed from different perspectives. Basically many types of industrial lasers like, carbon dioxide (CO2) laser and neodymium-doped yttrium aluminium garnet (Nd: YAG) laser, fiber laser, semiconductor laser which are used for laser engraving process. Some important laser processing parameters and their effects on MRR and surface roughness are discussed. This paper deals with the review of papers by authors.
