CNC (Computer Numerical Control) Machining is the use of computer controlled machine tools functioning under numerical control to remove unwanted material from a work piece. Computer programs are used and customized to the requirements of a specific object or component, and controls various aspects, including the feed rate, location, speed and coordination.

Used in the manufacturing of both plastic and metal parts, CNC machines also control the exact positioning as well as the velocity. Also read more about The Importance of a Good Jig in Precision CNC Machining.

Multi-axis machines are more advanced CNC milling machines and add two additional axis (more than the normal XYZ or 3 Axis Machine) and allows work pieces to be moved on C or Q axis'. This allows a work piece, mounted horizontally, to be rotated along various axis, allowing both eccentric and asymmetric turning.

In 5 axis CNC machining, the fifth axis is responsible for controlling the tilt of the tool. This enables CNC machining companies to produce parts that have extremely complicated geometries. A great example of what 5 axis CNC machining operations can achieve is the organic geometries of the human head.

A CNC lathe is capable of creating a fillet by moving the cutting tool around the corner of a part, while CNC milling machines are capable of moving and endmilling along a circular trajectory or sloped line.

Each axis of movement is implemented in one of two ways:

1. By moving the tool itself, or

2. By moving the table (onto which the work piece to be machined is attached).

How these axes are is configured can vary, enabling machines with the same number of axes to perform different movements.

Conversational programming and CAM (Computer Aided Manufacturing) programming is used in order to program CNC machines, CAM being the most powerful of the two methods.
