Understanding CNC Machining
Computer Numerical Control (CNC) machining is a subtractive manufacturing process that utilizes computer-controlled machines to remove material from a workpiece. The process begins with a CAD (Computer-Aided Design) model, which is translated into a set of instructions (G-code) for the CNC machine. This allows for high precision and repeatability in producing complex shapes and intricate designs.
Technical Features of CNC Machining
CNC machining offers a range of technical features that enhance its effectiveness in manufacturing. The following table summarizes these features:
| Feature | Description |
