INDUSTRY 4.0 INDIUM GALLIUM NITRIDE DIODE LASER ENGRAVER

Laser engraving is an advanced technology in material processing that involves removal of material layer by layer. The aim of this research paper is to obtain digitally designed patterns and pictures on materials using InGaN (indium gallium nitride) laser module and to measure certain characteristic features of this advance laser technology. A novel tabletop CNC laser milling machine is specially built up to for using the laser engraving. The time taken to complete the engraving operation is measured using different techniques for different resolution in the design. The adaption of internet of things and Industry 4.0 featured a low-cost CNC laser engraver is special useful for learners to explore further research on the laser field.
