ABSTRACT
Milling machines produce mainly flat surfaces by means of a rotating cutter with multiple cutting edges. The two main types of machine are the horizontal and the vertical spindle. Milling cutters usually have teeth cut on the periphery and/or at the end of a disk or cylinder. Alternatively, inserted-tooth cutters with replaceable teeth may be used. In horizontal milling, up-cutting is the usual practice, but down-cutting may also be used. The types of cutter are listed in the following (Figure 19.1).
