The Facing Operation

Facing on a milling machine is the process of cutting a flat surface perpendicular to the axes of the milling cutter. This process removes the material by rotating the facing tool in the counterclockwise direction as the table feeds the workpiece across the cutter. Face milling can be achieved with an end mill but is often done with a face mill, shell mill, or fly cutter.
