Types of milling AS Precision actually runs

The milling service page names three methods: plain milling, face milling, and form milling. That is the entire published taxonomy — this article does not invent climb vs conventional or a cutter-brand list.

Plain milling puts the cutter axis parallel to the surface being generated. It is the path for slots, steps, and long flats.

Face milling puts the cutter axis perpendicular to the face. It is how a blank becomes a datum and how a cover gets a flat that a gasket can seal.

Form milling is the named route when the cutter itself carries the profile — a shape that would be slow to interpolate as a 3D surface.

Machines behind those methods, per the same page: vertical mills, multi-axis machines, and machining centers. Tolerance band published: ±0.001–0.005 in.
