The machine can cut on different types o f materials such as sheet iron, pipes and tubes. This study presented three design options such as Option 1 (Stepper motor and normal screw), Option 2 (Servo motor+ball and roller screw) and Option 3 (Stepper motor+ ball and roller screw). Based on the advantages and disadvantages o f these options, Option 2 was chosen because it was the most optimal fo r the existing budget and equipment conditions. According to Option 2, the technical drawings fo r CNC machining were designed using Autodesk Inventor 2020 software with the dimensions and technical requirements to be able to build the CNCplasma cutter completely. The simulation test results on Mach3 software showed that this machine with a working area 1000 X 800mm ensured safe operating conditions and met technical requirements. Therefore, this CNCplasma cutting machine can be used fo r display and teaching purposes.
