The Possibility of Creating a Low-Cost Laser Engraver CNC Machine Prototype with Platform Arduino

Abstract

Some of the advantages of CNC machine use are high processing quality and the speed of the final machining of the product. In the paper we present the low cost solution while the goal was to design and implement a 3D model of a CNC machine based on laser engraver that does not contain too many parts (not only because of the price but also because of defectiveness) and to optimize it for easy production use. When implementing, those parts were focused on that are easily accessible for ordinary consumers or they can produce them themselves. Arduino has been used as a microcontroller. The software part was a created GUI that allows direct communication with the laser engraver machine based on the designed 3D model of the processed product, generating and sending a Gcode to the machine through the USB port. In the paper we compared the results of laser engraving by our designed engraver CNC machine and the professional solution Akshar Fiber-Pro Laser.

Construcción de una máquina CNC de corte y grabado por láser

“…Así mismo, la gran variedad de láseres disponibles actualmente ha incrementado el número aplicaciones de corte y grabado de calidad, así como de manufactura en una amplia gama de materiales (CNC MEXICO 2020), (Ramon and Alexis 2018), (Hubeatir, Al-kafaji, and Omran 2018). En este sentido, se han propuesto y desarrollado máquinas para corte y grabado, a partir del uso de software libre y plataformas electrónicas como Arduino, tarjetas controladoras para el movimiento de motores y láseres con la suficiente potencia óptica, lo que les da las características antes mencionadas (Correa, Toombs, and Ferreira 2017;Khalid, Al, and Rameshkumar 2016;Koprda et al 2020;Pajaziti, Asllani, and Gjelaj 2017). Por ejemplo, (Vijayakumar et al 2020) desarrollaron un prototipo portátil para corte y grabado CNC láser con una potencia óptica de 20 W, presentando resultados de grabado y corte en papel y madera.…”

Selected Properties of Plywood Bonded with Low-Density Polyethylene Film from Different Wood Species

“…Wood-based materials are popular materials that are still used extensively as an alternative to solid wood across many industries. Among wood-based materials, plywood is widely used in diverse fields, including housing construction, vehicles, laser engraving and interior decoration, furniture production and many others [ 1 , 2 ]. According to the latest data released by FAO [ 3 ], during the ten-year period from 2009 to 2018, plywood global production and consumption volumes increased by 101% and 104%, respectively, which amounted to record values in 2018 of over 163 and 161 million m 3 , respectively ( Figure 1 ).…”
