CNC machining is a manufacturing process that uses computer numerical control (CNC) to automate and machine parts with extreme precision and repeatability. It is one of the most common and versatile manufacturing processes used today.
CNC machining works by using computer-controlled equipment to remove layers of material from a stock piece in order to produce a custom-designed part. The process starts with a CAD (computer-aided design) model of the part, which is then converted into CNC programming code.
The CNC code contains precise instructions for the tools on the CNC machine to follow. This could involve movements in 3 axes (X, Y, and Z) for milling and drilling machines, or rotational movements on lathes. Advanced 5-axis CNC machining services simultaneously controls movement on 5 axes, allowing for very complex geometries.
The part is machined from a block of material, called the workpiece, clamped inside the CNC machine. Common materials include metals like aluminum, steel, titanium, brass, and plastics like ABS, nylon, and acetal. The cutting tools move across the workpiece, removing material according to the programmed paths.
Extreme precision down to tolerances as tight as 0.001 inches.
Ability to machine very complex 3D shapes that would be infeasible manually.
Highly repeatable process perfect for manufacturing multiple identical parts.
Faster and more efficient machining compared to manual methods.
Minimal material waste by using optimized tool paths.
Suitable for low to high production volumes.
With its speed, precision, efficiency, and versatility, CNC machining is an essential manufacturing process used across a wide variety of industries such as aerospace, medical, automotive, and more.
