operations performed on the mill include but are not limited to side and face milling, fly cutting, and precision boring. Mills are classified on the basis of the position of their spindle. The spindle Operates in either a vertical or horizontal position. The amount of horsepower the mill is able to supply to the cutter is also often important.

The process of removing material from a workpiece by advancing rotary cutters cutter into it is called milling. The process is carried out by adjusting pressure, speed of cutter head, and direction of feed. A milling machine is a piece of equipment that removes a layer of material from the surface by using a multipoint cutting tool.
