Common Milling Operations
Milling Flat Surfaces
One way to mill a flat surface is by plane milling (Figure 23.1). Adjust the milling cutter
vertically to give the needed depth of cut while the workpiece is held on the table and
slowly feed it horizontally. Every tooth on the periphery of the cutter removes a chip every
revolution. Milling wide, flat surfaces this way is called slab milling.
Figure 23.1 One way to mill a flat surface is by plane milling.
Another way to mill flat surfaces is by face milling. In this method, the cutter teeth
operate at right angles to the cutter axis. Inserted-tooth face-milling cutters (Figure 23.2)
face mill large surfaces.
Figure 23.2 Inserted tooth face milling cutters face mill large surfaces.
