What is CNC Milling?
Computer numerical control (CNC) milling is a machining process that employs computerized controls and cutters to carve and shape metal or other rigid materials. CNC milling machines contain a spinning cutter that removes pieces of the workpiece through translating it in multiple axes. The cutter follows a programmed toolpath to machine the desired geometry specified in the computer-aided design (CAD) model. This automates what was previously a manual process and enables fast, precise, and repeatable fabrication of complex parts.
Types of CNC Milling Machines
There are several common types of CNC milling machines suited for different applications:
Type Description
Vertical Milling Machine The spindle is mounted on a ram that can move vertically on a column, useful for machining flat surfaces.
Horizontal Milling Machine The spindle is fixed while the table can move horizontally on a track in X and Y axes, best for profiling applications.
Universal Milling Machine Combines both vertical and horizontal milling, with a spindle that can tilt to mill at angles for complex parts.
5-Axis Milling Machine Allows movement in 5 linear axes (X,Y,Z translational and A,B rotary) enabling intricate sculpted surfaces.
The CNC Milling Process
Below is a brief overview of the standard CNC milling process:
A CAD model of the part design is created.
The CAD file is converted into a G-code program the CNC can understand using CAM (computer-aided manufacturing) software.
The workpiece material is securely clamped in the machine vice or fixture.
The cutting tool is mounted on the spindle and positioned at the workpiece origin.
The G-code is input and the CNC machine removes material layer by layer as per the programmed toolpath.
Upon completion, the milled part is removed for any required post-processing.
Benefits of CNC Milling for Metal Fabrication
Some key advantages of CNC milling for precision metal fabrication include:
High accuracy to tolerances of ±0.005 mm or better for demanding applications.
Ability to machine complex geometries with tight radii and angles through multi-axis control.
Consistency and repeatability through automated, programmed motions.
Cost-effectiveness for medium to high volume production runs.
Machines a wide variety of metals like steel, aluminum, titanium, and more.
Ease of programming through standard CAD/CAM workflows.
Applications of CNC Milling in Different Industries
