Milling – Introduction to Mechanical Design and Manufacturing
End milling: This operation uses a cutting tool with one or more flutes to remove material from the edge or corner of a workpiece. The cutting tool rotates parallel to the workpiece, creating a groove or profile. The cutting in milling operations can be performed in two different ways: conventional or up milling and climb or down milling.
