CNC milling is the process of precisely shaping and machining a workpiece using “Computer Numerical Control” (CNC) technology. In this process, CNC machines are programmed with specialized software and operate according to these programs to machine various materials such as metal, plastic, wood, or composite materials.
Key Features of CNC Milling
- Precision: CNC machines operate with high precision and can easily create complex and detailed geometries.
- Automation: CNC mills minimize human intervention through automation, which reduces errors and increases productivity.
- Versatility: Can be used for various cutting, drilling, carving, and shaping operations.
- Repeatability: CNC machines can produce the same part repeatedly with consistent dimensions and quality.
- Speed and Efficiency: Offers faster and more efficient production compared to traditional methods.
Working Principle of CNC Milling
- Design and Programming: The part design is created using CAD (Computer-Aided Design) software and converted into machining codes using CAM (Computer-Aided Manufacturing) software.
- Cutting Tool and Movements: The CNC machine processes the material by moving the cutting tools along different axes according to the programmed codes.
- Cooling and Cleaning: Coolants are used during machining to cool the material and remove chips.
