What is CNC Milling?
CNC milling is a manufacturing process that uses computer numerical control (CNC) technology to automate the operation of milling machines. Milling is a machining process that involves removing material from a workpiece using rotary cutters to create custom shapes, parts, or designs. CNC milling machines follow programmed instructions (G-code) to precisely control the movement of the cutting tools and workpiece, enabling high accuracy and repeatability.

Types of CNC Milling Machines:
1. 3-Axis CNC Mills: Move along the X, Y, and Z axes for basic machining tasks.
2. 4-Axis CNC Mills: Add a rotational axis (A-axis) for more complex geometries.
3. 5-Axis CNC Mills: Include two rotational axes (A and B) for highly complex and precise parts.
Advantages of CNC Milling:
1. Precision: High accuracy and tight tolerances (up to ±0.001 inches or better).
2. Versatility: Can machine a wide range of materials, including metals, plastics, and composites.
3. Complexity: Capable of producing intricate geometries and complex parts.
4. Repeatability: Ensures consistent quality across multiple parts.
5. Automation: Reduces manual labor and increases production efficiency.
