Cutting polystyrene shapes using a heated wire, is a method widely used in making mounds, volumetric letter cut-outs or 3D shapes. In order to reach a very good quality and precision of the cut in polystyrene, it is necessary to take into account parameters that can vary depending on the cutting speed, working environment, amperage introduced in the heated wire. This paper shows how to build a CNC machine that cuts with nickel wire. This machine has 4 working axes (two vertical axes and two longitudinal axes). The aim of the research is to build an automatic and autonomous polystyrene cutting machine. The machine control system uses an Arduino mega 2560 microcontroller. The cutting process is performed by sending the G code file through a serial USB or by loading the code on a SD card, the machine has the autonomy to work without the use of a computer. After sending the code by the microcontroller, it activates the stepper motors.
