  1. 1. Investigations of Tool Wear Mechanisms in the Turning of Conventional, Calcium Treated and Ultraclean Steels

    Master-uppsats, KTH/Materialvetenskap

    Författare :Milou Göransson; [2023]
    Nyckelord :Clean steel; Ultraclean steel; Longitudinal turning; Cemented carbide cutting tool; Chemical vapor deposition coating; Machinability; Tool wear; Non-metallic inclusions; Rent stål; Ultrarent stål; Längdsvarvning; Hårdmetall skärverktyg; Kemisk ångdeponering beläggning; Bearbetningsbarhet; Verktygsslitage; Icke-metalliska inneslutningar.;

    Sammanfattning : Application of clean and ultraclean steels have shown to provide favourable mechanical properties for bearings and transmission components, specifically regarding fatigue performance, compared to conventional steel grades. Clean steels are characterized by containing a very low level of non-metallic inclusions. LÄS MER

  3. 2. Temperature effect on insert tool life in dry machining

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :William Hagberg; [2021]
    Nyckelord :Milling tool; Temperature; Wear; Simulation; Cooling; Heat sink; Insert;

    Sammanfattning : This thesis work researched the temperature effects the insert tool life. This was examined through physical laboratory testing with designed milling tools and temperature simulations in ANSYS. The designed milling tools altered the temperature in the insert through external parameters like design and material. LÄS MER

  4. 3. Development of a Laboratory Test Method for Assessment of Crater Wear Volume on Inserts for Steel Turning

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Joakim Sandberg; [2019]
    Nyckelord :Crater wear; turning; focus variation; volume;

    Sammanfattning : This thesis project was carried out at Sandvik Coromant in Västberga, Sweden with the purpose of developing a new laboratory test method for volumetric assessment of crater wear on inserts for steel turning. The test method was developed with the Sandvik Coromant´s existing crater wear measurement method as a starting point. LÄS MER

  5. 4. Exploratory study of the interactions between textured alumina coatings and steel

    Master-uppsats, KTH/Materialvetenskap

    Författare :Jonas Svantesson; [2018]
    Nyckelord :alpha Al2O3; diffusion couple; chemical wear; crater wear; DICTRA;

    Sammanfattning : The crater wear of alumina coated WC-Co cutting tools is thought to be influenced by the chemical reactions between the coating and the workpiece material. Three different crystal orientations ((001), (012), and (100) of alpha alumina CVD coatings are examined in combination with four workpiece materials of steel to establish what reactions are present, and the extent of diffusion.

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

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Tillämpad materialvetenskap

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

    Sammanfattning : 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. LÄS MER
