A G-Code Controlled Mini Milling Machine is a compact CNC setup designed for precise cutting, drilling, and shaping of metal, wood, or plastic parts. It operates based on G-code instructions, allowing complex machining tasks to be performed automatically with high accuracy. This machine is ideal for engineering students, prototyping labs, and hobbyists who want hands-on experience with CNC manufacturing.

Parts Used:

1. Mini Milling Machine Frame – base structure for stability
2. Spindle Motor – performs cutting or drilling
3. Stepper Motors & Drivers – control X, Y, and Z axis movement
4. Lead Screws / Ball Screws – provide smooth linear motion
5. Linear Bearings & Rails – ensure precise travel
6. CNC Controller Board (Arduino + GRBL, Mach3, or similar)
7. Power Supply Unit – for motors and spindle
8. Limit Switches – prevent over-travel
9. CNC Software (e.g., Fusion 360, Mach3, GRBL Controller) – for design and control
