Abstract Due to the current development requirement of expanded polystyrene(EPS) manufacture, a low-cost and portable polystyrene foam cutting system was developed. This system integrated the knowledge of CAD/CAM, motor control, CNC, advanced manufacture to determine its design scheme, develop host computer software, and finally program graphical user interface (GUI) optimization, optimization sequencing of graphic elements based on DXF file and cutting path planning. Additionally, software functions were tested and a real foam part was cut in the system. It has been proved that the system is easy to use and dimension tolerance is small which can satisfy the requirement of engineering application．
