What is CNC Milling? (150 words):
Computer Numerical Control (CNC) milling refers to automated cutting operations, utilizing specialized machinery to shape various materials such as metals, plastics, and composites. These machines remove material from the workpiece using rotating cutter tools guided by pre-programmed instructions.

The production of prototypes through CNC milling involves transforming three-dimensional digital designs into tangible products. The process follows an ordered series of steps:

1. Design Creation: Computer-Aided Design (CAD) software is used to create digital models or blueprints.
2. Conversion to Machine Language: CAD files are translated into machine-readable instructions via Computer-Aided Manufacturing (CAM) software.
3. Tool Selection: Depending on the material and desired outcome, appropriate cutting tools, such as end mills or drills, are chosen.
4. Machine Set-up: Workpieces are securely clamped onto the CNC milling machine's table and aligned accurately for operation.
5. Execution: The CNC milling machine carries out precise cutting movements based on the programmed commands.
6. Post-processing: Additional finishing processes may be required, such as deburring, sanding, or polishing, depending on design specifications.

Advantages of Prototype CNC Milling (200 words):
Prototype CNC milling offers numerous advantages over traditional manufacturing methods when it comes to developing prototypes:

1. Enhanced Precision: CNC milling machines ensure exceptional precision and consistency, providing accurate replication of complex designs within micrometer tolerances.
