Comparison between Upmilling and Downmilling Operations on Tool Wear in Milling Inconel 718 The evaluations of the results are focusing on the comparison of upmilling and downmilling operations using physical vapor deposition (PVD) coated carbide inserts. Machining parameters; depth of cut, feed rate and cutting speed are FullText Paper (PDF): Comparison between Upmilling and Downmilling Operations on Tool Wear in Milling Inconel 718 Down milling is a better choice than up milling as we get the best finishing surface as well as there is less heat generation.
But in some exceptional conditions you have to use up milling. In this article, we have learnt about the difference between up milling and down milling. Down milling requires lesser force comparing to up milling. Chip thickness is zero at the entrance of cutting tooth and maximum at tooth exit. Chip thickness is maximum at the entrance of cutting tooth and minimum at tooth exit. When i see jorge helping other people with their essay and not me.

Type of MILLING MACHINES. Milling machine are classified on the base of the position of their spindle. namely, upmilling and downmilling. Upmilling is accomplished by rotating the cutter against the direction of the feed of Today we will discuss about difference between up milling and down milling. The milling is a machining process in which, a rotary cutter i used to remove the material from work piece in the direction perpendicular t the axis of rotation.
In downmilling there are two distinct ways to cut materials when milling, conventional (up) millingand climb (down) milling. The difference between these two techniques is the relationship of the rotation of the cutter to the direction of feed.
