  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

  3. 2. Simulation of fatigue crack growth in coated cemented carbide milling inserts

    University essay from KTH/Hållfasthetslära (Avd.)

    Author : André Tengstrand; [2017]
    Keywords : ;

    Abstract : The aim of this work is to create a nite element model that simulates fatigue crack growth in coated cemented carbide milling inserts. A typical fatigue wear of coated milling tools are comb crack formation on the cutting edges of the tool inserts. Comb cracks initiate from pre-existent cooling cracks in the coating layers.

  4. 3. Tool wear in turning of titanium alloy Ti–6Al–4V : Challenges and potential solutions for crater wear, diffusion and chip formation

    University essay from Uppsala universitet/Tillämpad materialvetenskap

    Author : Erik Bamford; [2016]
    Keywords : Wear; Titanium; Ti6Al4V; Diffusion; Crater Wear; Chip Formation; Shear Strain; Cracks; Turning; Cutting Tools; Cemented Carbide; TiCN; Coating; Sandvik; Coromant;

    Abstract : Titanium alloys are major materials used in the airplane industry, and prospects show that airplane production will double in the next 20 years. Consequently, the demand for cutting tools for machining of titanium alloys will increase. The primary problem when machining titanium alloys is their low thermal conductivity. READ MORE

  5. 4. Residual stress in CVD coatings : Evaluation of XRD and TEM methods for micro and macrostress determination

    University essay from Uppsala universitet/Tillämpad materialvetenskap

    Author : Dennis Karlsson; [2015]
    Keywords : residual stress; transmission electron microscopy; TEM; nanobeam diffraction; x-ray diffraction; XRD; CVD; TiCN; Al2O3; ZrCN; blasting;

    Abstract : Cutting tools are subject to extreme environment during processing, with hightemperatures and pressures. CVD coatings are used to increase lifetime andperformance of the WC/Co composite. Residual stresses in the coatings areinteresting as they may be destructive or constructive for the material duringoperation. READ MORE
