  1. 1. Modeling and Analysis of the Shot Peening Process : a Study of the Residual Stresses in an Insert using the Finite Element Method

    University essay from Linnéuniversitetet/Institutionen för maskinteknik (MT)

    Author : Hamid Torkaman; [2018]
    Keywords : Shot peening; Residual stresses; Cutting tool inserts; Post-coating treatment; Coated cemented carbide;

    Abstract : Cutting tool inserts are often coated with thin layers either through chemical vapor deposition (CVD) or physical vapor deposition (PVD) processes. In order to have a better wear resistance cutting tools are mostly subjected to post-coating treatment processes. READ MORE
