... is validated by treating the rake faces of high-speed steel cutting tools and performing orthogonal cutting experiments in which the tools peened at the impact angle of 75 deg exhibit lower cutting and thrust forces than those peened at 40 deg. Additional peening parameters, namely, the particle volume ratio...
