Face milling is a machining technique used for flattening and smoothing the surface of workpieces. Machinists use two types of machines for this process which could be either a machining center or a milling machine. The major difference between this process and traditional milling techniques is that the milling machine or machining center is perpendicular to the workpiece. This means the top of the machine mills the workpiece instead of the side used in other milling techniques.
The face milling process could either be manual or automatic. The difference between both is just the feed rate. For the manual face milling, the machinist would have to stop the machine repeatedly to move the workpiece across the table while the feed rate for the automatic type is more constant. This makes the automatic type less prone to mistakes or wrong cuts.
The process uses various face mill cutting tools, including end mills, shell mills, and fly cutters. The machine rotates the tool counterclockwise and moves the workpiece across its teeth.
