    With high speed of technology development, Plasma CNC machine plays an important role in industry, as it can cut any metal using only compressed air ignited at high voltage and high frequency. The cut is fast, clean and highly accurate. This report shows how plasma CNC machine was built step by step. Plasma CNC machine contains several parts: plasma unit, controller circuit, CNC table and software. Plasma unit generates the plasma torch which can cut the metals. Controller circuit controls the stepper motors using micro stepping method. This method has high accuracy control. CNC table design and analysis was performed by Autodesk Inventor software. CNC table contains three axes Y-axis, X-axis, Z-axis which move using rods and rails as linear motion system. It is strong and stable. Plasma trace Software was used to convert images to G-code that will be loaded to ARDUINO software and arduino will send commands to controller circuit by parallel port to move the axes. The plasma CNC machine was tested and gave good results with high accuracy Keywords: Plasma Arc Machining, Oxygen plasma, laser-cutting, CNC.
