Up Milling: Down Milling: 1. This machine is also called as conventional milling. This is called a climb down milling. 2. The cutting forces act upward. The cutting forces act downward. 3. Mostly used for rough cutting operations. This is used for finishing operations. 4. Due to the more tool wear rate, the durability of the tool is less.
Read OnDown 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 …
Read OnDifference Between Up Milling And Down Milling. Difference Between Up Milling And Down Milling. 1. There is propensity to lift workpiece so extra clamping forces are required to fix job on table. Forces are enough on job to press down. Thus clamping difficulty is not so much. 2. Cutter turns against direction in which the work is being fed.
Read OnThe right type of contact between the edge and material at the entry and the exit of a cut must be considered for successful milling. In a milling operation, the workpiece is fed either along or against the direction of the cutter rotation, which affects the start and finish of the cut, as well as if down milling or up milling method is used.
Read OnBy comparing both the figures it is found that the shape of the metal chip removed by the cutter is the same in both the cases. But in up milling, as the cutting proceeds, the chip thickness increases gradually whereas, in the down, milling chip thickness decreases slowly. In other words, chip thickness in up milling is zero at the start and ...
Read OnWhereas in the down milling, the cutting force varies as a maximum at the beginning and minimum at the end. In up milling, The force of cutting tends to lift up the work since it is directed upwards. Hence fixturing is difficult. But in the down milling, The force of cutting is directed downwards and keeps the job pressed against the table.
