This paper presents a study on the development of a manufacturing system of printed circuit boards through copper milling. An advantage of this system is the replacement of chemical processes by physical process presenting a sustainable solution. The paper uses programs that will generate G-code needed to establish the coordinates where the milling forms the tracks. After obtaining the code, it will be transformed into steps that will be sent through the serial port to the microcontroller and the serial communication control will be in software. After obtaining information the microcontroller will execute the movement of the stepper motors through their drivers, H-bridge, the microcontroller also drives the spindle motor responsible for rotating the grinding tool, using a driver with a optocoupler and TRIAC
