MANUFACTURING INC.
CNC milling is a highly precise, computer-controlled manufacturing process used to create complex parts and components from solid materials. Unlike traditional machining, CNC (Computer Numerical Control) milling automates cutting and shaping through pre-programmed software—delivering exceptional accuracy, repeatability, and speed.
It’s a subtractive process, meaning it removes material from a workpiece using rotating cutting tools until the final shape is achieved.
CNC milling stands out for its ability to:
Handle complex designs with high dimensional accuracy
Reduce human error through automation
Perform secondary or finishing operations on pre-machined parts
Support high-volume and custom production
This versatility makes CNC milling a go-to solution for industries like aerospace, automotive, marine, oil & gas, and more.
CNC milling machines use a combination of:
Cutting tools with multiple sharp teeth to remove material
Spindles to rotate the tool or workpiece at high speeds
Feed systems to control movement with precision
CAD Design
Engineers create a 2D or 3D model of the desired part using computer-aided design (CAD) software.
CAM Programming
The CAD file is converted into machine instructions using CAM (computer-aided manufacturing) software. This generates G-code, which tells the CNC machine how to move.
Machine Setup
The workpiece is secured on the machine bed, and the correct tools are installed.
Milling Operation
The operator initiates the milling cycle. The machine uses the uploaded code to move cutting tools on multiple axes, precisely shaping the material.
Different jobs require different milling methods. Here are some of the most common:
Plain Milling (Surface Milling)
Cuts flat surfaces parallel to the tool axis.
Face Milling
Cuts flat surfaces perpendicular to the tool axis—often for smoother finishes.
Angular Milling
Cuts at angles to create grooves, chamfers, or angled edges.
Form Milling
Produces curved surfaces, contours, and complex shapes using specially shaped tools.
Modern manufacturers rely on CNC milling because it:
Delivers tight tolerances and fine finishes
Scales from prototypes to high-volume production
Integrates easily with CAD/CAM design processes
Reduces time and labor costs
