Milling is the machining process of using rotary cutters to take away material from a workpiece advancing in a direction at an angle with the axis of the tool. It covers a wide variety of different operations and machines, on scales from small individual parts to large, heavy-duty gang milling operations.
Turning is a machining process in which a cutting tool, ideally a non-rotary tool bit, describes a helical toolpath by moving more or less linearly while the workpiece rotates. sense).
