Design, Contraction & Perform Test of Three Axis CNC Milling Machine.

Abstract

This project outlines the design and components of a 3 axis CNC Milling machine controlled by an Arduino UNO micro-controller. The system integrates a NEMA 17 stepper motor, Motor Driver Shield v3, A4988 Motor Driver, and a 775 DC motor (12V) for precise and controlled movement. Linear bearings (12mm), shaft rods, and 608zz bearings contribute to the smooth motion of the machine. The inclusion of an 8mm CNC screw nut and patch rod, along with a 5*8mm pulley, ensures accurate linear and rotational motion. Power is supplied through a 12V adapter with a female connector. This comprehensive setup allows for versatile CNC operations, showcasing a blend of precision and adaptability in the fabrication process.
