Abstract

A 2D finite element model of three different rake angles (8°, 12° and 16°) was developed to simulate the peripheral milling of Ti-6Al-4V alloy. This was validated by machining experiments performed using a specially made solid carbide single flute fly cutter. The investigations indicated that this approach estimates the resultant cutting forces with prediction errors of 11%-26%, depending on the rake angle. This confirms the potential of finite element modelling to assist with the selection of cutting tool geometry for specific applications. However, this approach revealed that special attention should be paid to appropriate selection of the Johnson-Cook (J-C) constitutive parameters.
