Desarrollo de un prototipo de fresadora CNC de 4 ejes de bajo costo basado en Arduino para prácticas educativas

Abstract

Currently, the use of CNC machines is becoming increasingly popular among many educational institutions to carry out multiple machining jobs and create other projects, although there are a large number of types of CNC machines that can be created using low expensive materials. There are certain types of CNC that are more difficult to build, such as a four- and five-axis CNC or those with very advanced systems. This project proposes the design and construction of a functional prototype of a 4-axis CNC milling machine, controlled by an Arduino Mega controller. The main goal of this project is to provide a teaching tool that allows students to become familiar with the operation and programming of CNC machines. For this project development, several bibliographic sources and research have been consulted in order to understand the entire process necessary for the design, construction and operation of a CNC machine. At the end of the prototype, different functional tests were carried out on the prototype in order to verify the correct functioning of the main functions such as machining the parts and that the code works without errors when giving instructions to the prototype.
