： In the process of micro milling, the tool diameter is small and the wear is fast. The tool wear has obvious nonlinear effect on the micro milling force, and the tool run-out has different effects on the wear of per tooth. These factors will lead to the instability and precision of machining process. However, the general micro milling force model …
