In micro-milling, down milling mode generates larger wavy-type burrs, while up milling mode produces smaller ragged-type burrs. Cutting edge radius and progression of tool wear are factors driving burr size growth. To reduce burr size, a cutting tool with a very small edge radius should be selected, and the tool can be coated to extend its life.
