Efficient Use of Electronic Waste for CNC Machine

Abstract

In order to minimize the cost of the CNC machine, this paper proposed an idea to recycle the waste material of the old computer system. The implementation of this paper consists of the followings: Arduino UNO R3 board, Stepper motorsfor the motion of X and Y axes, mini Servo motor, L293D driver IC, Arduino Processing software (freeware), Inkscape software to create G-codes for the input data (freeware), any type of pen or pencil-as the main source of ink. This project is able to draw complex line drawings by plotting the coordinates using a simple algorithm. Plotting of coordinates is cultured within G-codes prepared by a software after which it is transferred to the microcontroller by which the motor mechanism is instructed to draw the image or text data, motor mechanism includes X-and Y-axes that can each work independently, yet simultaneously.

Low Cost Multifunctional CNC Laser and Mill Built From the Reuse of Computer Equipment and E-Waste: Rem-CNC Router

“…This way, it was possible to make several changes to the original design by Walendorff (2020) in order to obtain an increase in the work area of the REM-CNC Router, in addition to allowing the easy change of the tool used in the machine. Verma, Gianchandani and Saroha (2018) state in their study that the use of waste materials from computing devices and e-waste for the construction of robotics and automation projects causes great cost reduction, improves the cost-effectiveness and reduction of environmental impacts.…”

“…Later, this technology became known as Computer Numerical Control, allowing the control of the movement and operation of machine tools, having as main advantages the reduction of cost, production time, efficiency, agility, flexibility and precision (VERMA; GIANCHANDANI; SAROHA, 2018).…”

REM-CNC Router - CNC multifuncional Fresa e Laser de baixo custo construída reutilizando equipamentos de informática e lixo eletrônico

“…marlonnardi.com/p/construa-sua-propria-cnc-20-2.html. Analisando o projeto de Walendorff (2020) e levando em consideração que a proposta do projeto já era de baixo custo, percebeu-se que haveria uma redução de custos se fossem utilizados materiais reciclados para a construção da máquina CNC. Verma (2018) afirma em seu estudo, que o maior benefício na utilização de material residual de dispositivos eletroeletrônicos na construção de uma máquina CNC, é a relação custo-benefício e a diminuição de custo (VERMA; GIANCHANDANI; SAROHA, 2018).…”
