Identification of the appropriate model parameters in the cutting process is essential to achieve highly accurate cutting simulations that are effective for the process optimization. During end milling, tool damage deteriorates not only the side cutting edge geometry but also the corner cutting edge as the cutting distance increases. The conventional model does not consider the effect of local corner edge damage on the cutting force. Therefore, we proposed a model and its parameter identification method considering the corner edge damage. The tool life test verified that the corner damage modelling significantly improves the force estimation accuracy.
