Milling

The milling process is a machine tool that rotates a circular tool with numerous cutting edges arranged symmetrically about its axis, called a milling cutter.

The metal work piece is usually clamped to a table that can move in three perpendicular directions. Cutters of many shapes and sizes are available for a wide variety of milling operations. Milling machines cut flat surfaces, grooves, shoulders, inclined surfaces, dovetails, and T-slots. Various form-tooth cutters are used for cutting concave forms and convex grooves, for rounding corners, and for cutting gear teeth.
