  1. 1. Machinability study on GCI brake discs - Effects of material variations and process behavior on tool life

    Uppsats för yrkesexamina på grundnivå, Lunds universitet/Industriell Produktion

    Författare :Christian Jaunviksna; [2023]
    Nyckelord :Metal cutting Machinability Grey cast iron Tool wear Cutting data Hardness Microstructure Segmentation; Technology and Engineering;

    Sammanfattning : Grey cast iron is one of the most used materials in the automotive industry. The material has a range of properties that makes it suitable for machining applications, but manufacturers still experience machinability problems. LÄS MER

  3. 2. 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

  4. 3. Mechanical and tribological characterization of additive manufactured Co-alloyed tool steels aimed for cutting tool bodies

    Magister-uppsats, Högskolan Dalarna/Institutionen för information och teknik

    Författare :Jijesh Rajan; [2022]
    Nyckelord :Maraging steels; Selective laser melting; microstructure; wear; Modified 18Ni300; Osprey MAR;

    Sammanfattning : A drill tool body operates under tough cutting conditions where it is subjected to severe rubbing at the drill flute margin by the sliding chips. The tool wear caused by the contact stresses of the high-speed sliding chips is one of the common damage mechanisms observed in drill tool bodies. LÄS MER

  5. 4. Mechanical and tribological characterization of additivemanufactured Co-free tool steels aimed for cutting tool bodies

    Master-uppsats, Högskolan Dalarna/Institutionen för information och teknik

    Författare :Mayur Mane; [2021]
    Nyckelord :Co-free maraging steels; Co-free W360 AMPO alloy; hot-work tool steel; Selective laser melting; microstructure; wear;

    Sammanfattning : Additive manufacturing (AM) is an emerging and interesting technology that enables some of theproduct development projects (PDPs) to produce products that have mechanical and tribologicalproperties comparable to products that are conventionally manufactured. Selective laser melting(SLM) is an additive manufacturing technology that is predominantly used for the production of metalbased components (i. LÄS MER

  7. 5. Akustisk emission vid skärande bearbetning från den adhesiva mekanismen som funktion av förslitningsutvecklingen

    M1-uppsats, Högskolan i Gävle/Avdelningen för industriell ekonomi, industridesign och maskinteknik

    Författare :Johan Lundell; [2021]
    Nyckelord :Adhesion; Stagnation; Skärande bearbetning; Abrasion; Verktygsförslitning; Ljudmätning; Frekvens; Amplitud;

    Sammanfattning : The adhesive mechanism is one of the most significant degradation processes of the edge in metal cutting. Although knowledge about adhesion and edge buildup (BUE) has increased in recent years, there are still areas that are less explored. LÄS MER
