Design and Construction of a Low Cost CNC Milling Machine for Woodworking

Computer Numeric Control (CNC) machinery were created to reduce manufacturing times for industry, but this type of machinery is costly and therefore only a few uses can recover the investment. However, the progress of electronics in the last decades has allowed to develop affordable CNC machines. This article explains the design and manufacturing process of a low budget CNC milling machine for woodworking. All the structural elements were designed and simulated using PTC CREO, as well as the manufacturing sequence. The control hardware uses commercially available electronics such as Arduino ONE, and stepper motors to move the machine, while the software uses the free open source codes Vetrica Aspire and Universal G Code. The machine was tested on different materials, obtaining good results. The result is a CNC milling machine for woodworking that costs about 50% the price of an equivalent commercial machine, an can therefore be a suitable solution for craft industries.
