All About Milling in Machining

Conventional milling (or up milling) is a milling process in which the cutting tool rotates in the same direction as the workpiece's motion, so the tool moves in the opposite direction to the material feed. It is more applicable to higher ductility materials and allows faster machining. This results in progressive cutter engagement, increased ...
