Milling Operations – ToolNotes
End Milling. End milling is probably the most common class of operations performed on milling machines. End mills are cylindrical cutters that normally have two or more cutting edges on both the periphery and end of the tool. End milling operations include side milling, slotting, facing, or partial facing, pocketing, profiling, and contouring.Web
