What is upmilling and down milling? Different types of material removal Stratergy?

Question

Accepted Answer

Upmilling and down milling are material removal strategies used in milling operations.

Upmilling involves feeding the workpiece against the rotation of the milling cutter, resulting in a smoother finish and less heat generation.
Down milling involves feeding the workpiece in the same direction as the rotation of the milling cutter, resulting in a rougher finish and more heat generation.
Other material removal strategies include climb milling, conventional milling, and high-speed machining.
The choice of strategy depends on factors such as the material being machined, the desired finish, and the capabilities of the milling machine.
For example, climb milling is often used for roughing operations, while conventional milling is preferred for finishing operations.
