Implementación de una máquina CNC aplicando Arduino para la impresión y perforación de circuitos impresos.

Abstract

It is of the utmost importance the relevance that electronic devices have in our daily activities. These electronic devices have a fundamental element called printed circuit board which connects every single electric component that is part of the circuit. The printed circuit board is one of the most important elements, the objective of this degree project is the implementation of a CNC machine using Arduino for the printing and drilling of printed circuit boards through a three-axis milling method X, Y, Z improving both the printing and drilling process due to the fact the manual process is prone to make mistakes. The mechanical design of the CNC machine was developed from a CAD design, it was decided to select wood due to the ease for joining parts, its hardness, and its lightness, by the same token, the electric system was focus on the use of an electric card together with the stepper motor controllers. We used a PCB design software that is capable of creating a JPG file and then transformed it into Gcode in a software specifically created for this type of work, a control system using Arduino which interprets position coordinates of the code was also implemented. G. The last stage of the project was the operation of the CNC machine, verifying tests such as the displacement of the axes automatically. In the same way, we corrected the faults that were presented in the speed and displacement, ensuring a high level of design and printing of the PCB boards.
