A run-out measuring method using modeling and simulation in four-fluted end milling

The end mill center deviation with respect to spindle axis, that is called run-out, has significant effects on cutting force variation. Therefore, a run-out model must be included in a cutting force model to simulate accurate cutting force. In this paper, a method of modeling and simulation to measure a run-out in four-fluted end mill was developed. The simulated cutting force was compared with the measured cutting force and they had good agreements for their waves.
