The effect of runout on cutting geometry and forces

Cutter runout is a universal condition affecting the performance of multi-tooth metal cutting operations such as milling operations. In end milling, the use of set screw-type tool holders causes the milling cutter to be offset in the tool holder with the offset side of the cutter experiencing higher than average chip loads leading to higher peak forces and uneven tool wear on the cutter.
