Design, Control and Realization of a CNC Laser Engraving Machine

Abstract

Nowadays, CNC machines participate in metalworking industries such as machining operations (milling, turning, grinding, etc.), inserting components like PCBs, and drawing. Therefore, in our project, we designed a portable CNC laser-engraving machine for drawing. Our machine is precise, able to process or engrave complex drawings, does not require much space, and does not require an operator with high qualifications (just a simple computer user); also, it is very cheap for purchasing and maintenance. This is due to the open-source software used, the microcontroller board Arduino UNO based on the ATmega328P, the small stepper motors, and the simple mechanisms used to transfer the movement to the 4W laser. In our future work, we will reduce the vibration during the operating time and optimize machine geometry.
