CNC machining is a manufacturing process that uses computer-controlled machines to shape materials like metals and plastics. It involves interpreting digital designs and translating them into precise instructions for the machine's tools.

Common types include milling, turning, Complex Mill Turning, and 5-axis Machining.

CNC machining can be used on a wide range of materials, including metals (aluminum, steel, brass, etc.), plastics (ABS, nylon, polycarbonate, etc.), and composites.

The process involves creating a digital design, programming the CNC machine with instructions based on the design, setting up the machine with the appropriate tools and materials, and then allowing the machine to execute the program to shape the material.

Factors that can affect cost include the material used, the complexity of the design, the quantity of parts needed, and the machining time required.

Reputable CNC machining services have quality control measures in place to ensure the accuracy and precision of their work. It's also important to provide clear specifications and tolerances in your design.

CNC machining can be used for both prototyping and production, making it a flexible manufacturing process.
