Face milling may include a simultaneous shoulder milling operation. Unlike face milling, shoulder milling takes place with the cutting plane parallel to the axis of rotation, creating a flat or contoured surface on the workpiece periphery. Typical shouldermilling cutters usually have one or more rows of inserts. Slot milling creates a slot or ...
