End Milling

End Milling is a multipoint cutting process in which material is removed from a workpiece by a rotating tool.  The material is usually removed by both the end and the periphery of the tool.  Generally, the cutter rotates about an axis perpendicular to the surface.  On occasion a single-point tool, such as a fly cutter, may be used.

Process Characteristics

Uses a rotating cutter to produce a machined surface and creates small, discontinuous chips
Uses vertical and horizontal milling machines
Removes materials with the face and/or periphery of the cutter
Uses a wide variety of tools, including square end mills, ball end mills, shell end mills, and t-slot mills
Produces slots, angles, pockets, radii, and many other workpiece geometries
