Design and Fabrication of CNC Milling Machine

Abstract

This thesis report focuses on the development of a miniature CNC milling machine with high precision capabilities for manufacturing complex geometries. The aim is to create a machine that meets ISO standards and produces highly accurate machined parts that enhance machine performance and lifespan. Unlike existing CNC machines, this machine employs AI and sensors, such as ultrasonic sensors, to ensure precise component movement. The machine can manufacture parts like drone wings, which have better strength than those manufactured by casting. Additionally, the unique assembly structure of the CNC milling machine minimizes vibrations during machining. The fabricated machine is also portable and can be easily carried by two or three people. By loading the G and M code in the machine, the desired geometry can be achieved with almost negligible deviation from the CAD model due to the machine's superior accuracy. Overall, this project provides a solution for highly accurate and portable manufacturing of complex geometries in miniature CNC machines.
