in up milling tool rotates againest direction of feed, in down milling tool rotates in the same direction of the feed
Upmilling requires higher force compared to down milling
Tool wear rate is more in up milling compared to down milling
Up milling is used for rough cutting operations, Down milling is used for finishing operations
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 with and against feed.
in up milling: tool rotates againest direction of feed, in down milling : tool rotates in the same direction of the feed
up send mail
down load from attachment or seb site.
in up milling we machine the material from bigger dia to the smaller dia meter and in down milling the direction will be opposite as from bigger to smaller dia of cut
Is a combination of system parts together to create more massive systems and thus consists of an emerging system which is a compilation of subsystems of the original systems. In this design, the basic elements of the system are first identified in great detail, then linked together to form larger subsystems, which in turn are linked to each other at several levels sometimes until a complete, high-level system is formed at the end. This method is often similar to a "seed" model where the beginnings are small but eventually grow to be more complex and complete. However, these "organic strategies" may result in the interconnection of elements and subsystems that are developed in isolation to become a subject for local improvement versus working to conform to a global purpose of the system.
it refers to directoion of cutter rotation in relation to direction of feed
Down Milling:Cutting edge takes full thickness of cut at entry and thin cut at exit
Up Milling: Cutting edge takes thin cut at entry and full thickness at exit
The milling operation is used to facing of those work piece, which are not symmetrical from its axis. It is also used to cut pockets, drill, slot and shape the work piece according to the requirement.There are two ways to cut the material from the work piece through milling machine. 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. In this type of milling the tool spins against the direction of feed. In this milling process, the cutting chips are carried upward by the tool.In down milling, the cutter rotates clockwise while cutting the work piece from left to right. In this milling operation, the tool spins with the direction of feed. The cutting chips are carried downward by the tool.
