Abstract

Laser is the most commonly used technology in the various stream such as engineering, medical, design, and also the business. With the different parameter setup there is various process of the laser can be done. One of the process is the laser engraving process. Laser engraving process allowed the engraver or the laser operator to engrave variety surface of the material type with various of design since in the 21th century the laser engraving machine is coordinated automatically. The laser engraving technique itself holds the same concept of past decades of engraving process, which is removing the layer of surface to form the pattern, layer by layer, the only difference is the engraving technique nowadays using the laser to do engraving. With the laser engraving machine, it is possible to produce the product in mass production with a uniform result. The imagination is not limited since various design can be done. For the exact machine that capable of doing the engraving process is, carbon dioxide (CO2) Laser and neodymium-doped yttrium aluminium garnet (Nd:YAG) laser, fiber laser and semiconductor laser. The main goal for this project is to produce the good quality of product by doing the study of the surface morphology by setting various parameter to get the good result of engraving. The material will be observed and examined after the engraving process.
