Abstract
The design and fabrication of a CNC (Computer Numerical Control) plasma cutting machine represent a significant advancement in precision manufacturing, enabling efficient and accurate cutting of conductive materials such as steel, aluminium, and brass. This project focuses on developing a cost-effective, versatile CNC plasma cutting machine tailored for applications in metal fabrication, automotive, aerospace, and artistic design. The system integrates a robust mechanical framework, including a stable frame, gantry, and linear motion components, with a high-performance plasma power supply and automated torch height control (THC) for consistent cut quality. Electrical systems, powered by stepper motors and a CNC controller, ensure precise movement, while CAD/CAM software facilitates the translation of complex designs into G-code for automated operation. The fabrication process involved sourcing materials, assembling mechanical and electrical components, and rigorous calibration to achieve cutting accuracy within ±0.1 mm. Key challenges, such as managing thermal distortion and electromagnetic interference, were addressed through careful design and shielding techniques.
