Down milling vs. up milling - Coromant

In up milling (conventional milling), the feed direction of the cutting tool is opposite to its rotation. The chip thickness starts at zero and increases toward the end of the cut. The cutting edge has to be forced into the cut, creating a rubbing or burnishing effect due to friction, high temperatures and, often times, contact with a work ...
