Low cost semi-industrial 3GDL CNC vertical milling center design with non-ferrous metal machining capability

This work proposes the design of a low cost semi-industrial three degree of freedom CNC vertical milling center (VMC) with non-ferrous metal machining capabilities. The design seeks to mitigate the difficulties that acquiring a commercial industrial CNC can present, such as large dimensions, high cost and complications in its transportation within the plant. The proposed machine will be made up of 1 NEMA 23 stepper motor for each X, Y and Z axis, and will be controlled by open source firmware using an ATMEGA 2560 microcontroller. Likewise, the working area will be 320x180mm and will have a precision 100 microns with semi industrial capacities. This design is aimed at small and medium-sized companies that are looking for a low cost non-ferrous CNC milling machine that in turn has the quality, performance and precision of an industrial one.
