Difference Between Up Milling and Down Milling - mech4study

First one is named as conventional milling or Up milling and the other one known as climb milling or down milling. The main and basic difference between up milling and down milling is the direction of rotation of cutter to the feed. In up milling the cutter is rotate clockwise when cutting the work piece from right to left.

Milling Machine: Methods of Milling. Milling Processes

Milling is an important process of manufacturing technology and basically it refers to the removal of metal from the work piece using a tool which has several cutting points and is rotating about its axis. Thus each cutting point removes a little bit of the metal but since there are multiple such points and the tool is rotating at a fast speed, the overall removal is quite brisk.
