in late years. Ball end mills are commonly used for machining of dies. But during the machining of dies, cutting forces act on an end mill affects the cutting accuracy due to the bending of the tool as shown in Fig.1. In order to predict the accuracy of machined surface, it is necessary to predict cutting forces.
