CNC machining refers to any process that uses a CNC machine. This could be for routing, milling, drilling, or other types of work that is done with metal, wood or other materials. This is a manufacturing process that uses the automatic opportunity from the computer to create shapes or forms that must be precise.

The raw materials are first used, and then they are transferred to a CNC machine which uses cutting tools for these shapes. CNC machining requires computers with at least one microprocessor as well as several units of storage. The CNC can be programmed with CAD and CAM software systems to create precise movements.

CNC machining is automated, which saves time and money for the operator. When the machine is properly set up, the operator can load the materials and program it. The machine will then work automatically without the need for attention.

Operators need to be familiar with the machine before they can do any CNC machining. CNC can be added to the machine's general features. For example, adding CNC to a routing process automates it. Operators must be able to understand the machine and the codes, CAM or CAD, how to use them, and how to operate it. They must also be able to understand basic routing.
