Abstract

Laser engraving is the practice of using lasers to engrave or mark an object. A CNC control system is used to drive the movement of the laser head. Laser engraver is a device that can cut paper, engrave wood and plastic. Using laser, the engraving process will be very precise and clean can be achieved. This project was aim to build a machine that can do laser engraving with a minimal cost at least can do the stated function. It is controlled using a Raspberry PI which is the main control centre for the machine. The engraving sample is attached to x-axis so it only moves in x direction while the laser is attached to y axis so it only moves in y direction. Two stepper motor were used for moving both the x-axis and y-axis. A laser diode used was taken from computer dvd-rw that has output power 200 mW. From my findings, this low power laser diode is suitable for my project as it is able to achieve the objective. This laser engraver machine should be able to do marking that would have been done by other processes.
