Study on the Influence of Different Tool Edge Radius on Milling Ti6Al4V

Short tool life is one of the bottleneck problems in Ti6Al4V machining. Edge preparation plays an important role on tool life. To investigate the influence of edge preparation on cutting force, cutting heat and chip morphology et al, Finite element model (FEM) is established. The software adopted in this study is ThirdWaveSystems AdvantEdge. Experiment is designed to verify the validation of the FEM model. Based on the validated FEM, optimized edge radius is obtained.Copyright © 2010 by ASME
