# Precision CNC Milling for High-Quality Parts
## The Importance of CNC Milling in Modern Manufacturing
CNC milling has revolutionized the manufacturing industry by providing unparalleled precision and repeatability in part production. This subtractive manufacturing process uses computer-controlled rotary cutting tools to remove material from a workpiece, creating complex shapes and features with tight tolerances.
## How CNC Milling Works
The CNC milling process begins with a digital 3D model of the part to be manufactured. This model is converted into machine instructions (G-code) that control the movement of the cutting tool along multiple axes. Modern CNC milling machines typically operate on three to five axes, allowing for the creation of highly intricate geometries.
