Computer numerical control (CNC) is pre-programmed code that represents instructions for machines to perform exact movements. This code indirectly defines how to generate, construct, or change a virtual object into a real one.

A CNC machine, according to this definition, must interface with a computer that is equipped with software that translates numerical code into Cartesian coordinates. This enables the machine to work with high precision, much like a robot.

CNC milling

CNC milling is a machine operation that creates custom-designed parts or components by gradually removing material from the work piece with rotating multipoint cutting tools and computerized controls. Typically, these systems have three linear degrees of freedom. They have free movement along the X, Y, and Z axes while the work piece stays motionless. Milling is more ideal for prototype and short production runs due to its limited dimensional operation, which limits the speed of operations.

Definition of Milling

What exactly is milling? It is a type of machining in which tools are used to shape the workpiece, usually on a movable table, although some milling machines also use movable tools. Milling started as a manual operation by humans, but now most milling is done by CNC milling machines, which use computers to supervise the milling process. Although CNC milling provides greater precision, accuracy, and production rates, manual milling is still beneficial in some instances. Shorter turnaround times are available with manual milling, which requires a high level of technical competence and experience. It also has the advantage of being less expensive, and the user does not have to worry about programming the system.

CNC Milling: Applications and Material Types

Capabilities in Production

CNC milling's manufacturing capabilities encompass a variety of procedures such as:


CNC mills are more efficient at material conservation, which results in lower material costs over the machine's lifetime. CNC milling machines are used to make complex short-run manufacturing parts, precision components and parts, and prototype parts.

CNC Milling Machine Types

CNC milling machines are extremely versatile and may be used to perform a wide range of cuts and machining operations. In general, however, the work piece remains stationary while the cutting tool moves and rotates to remove material and finish the design. Different CNC milling machines will have different spindle settings, and will fix and move the workpiece in different ways. Horizontal Milling: When a spindle with a mounted cutting tool presses against a work piece, it is oriented horizontally. Using thicker and shorter cutting tools, horizontal milling can manage deeper and heavier cuts.

Vertical milling involves moving a rotating cutting tool up and down a vertically oriented spindle to remove material from a stationary work piece. The spindle and table on the turret milling machine can move perpendicular and parallel to the axis.

Multi-axis milling: CNC mills with four or five axes make it possible to do very detailed or complex machine operations. Multi-axis milling machines move along the X, Y, and Z axes as well as rotate along the A and B axes. This permits the work piece to be approached from any direction, allowing various operations to be performed at the same time.
