  1. 6. Performance of advanced tool steels for cutting tool bodies

    University dissertation from Karlstad : Karlstad University

    Author : Anna Medvedeva; Karlstads universitet.; [2010]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tool steel; cutting tool body; fatigue strength; stress relaxation; machinability; high-temperature properties; microstructure; TECHNOLOGY Materials science; TEKNIKVETENSKAP Teknisk materialvetenskap; Materialteknik; Materials Engineering;

    Abstract : Performance of indexable insert cutting tools is not only about the performance of cutting inserts. It is also about the cutting tool body, which has to provide a secure and accurate insert positioning as well as its quick and easy handling under severe working conditions. READ MORE

  2. 7. The effect of workpiece material and its microstructure on tool wear in metal cutting

    University dissertation from ; Chalmers tekniska högskola; Gothenburg

    Author : Philipp Hoier; [2019]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Scanning electron microscopy; Superalloy; Cutting tool; Wear; Cemented carbide; Steel; Machining;

    Abstract : The aim of the present work is to promote the basic understanding of how the workpiece material and its microstructure affect the tool wear during metal cutting. To isolate the effect of the workpiece material, the tool material (uncoated cemented carbide) was kept constant while the workpiece was varied. READ MORE

  3. 8. On tool steel, surface preparation, contact geometry and wear in sheet metal forming

    University dissertation from Karlstad : Karlstads universitet

    Author : Fredrik W. Lindvall; Karlstads universitet.; [2011]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wear; Galling; sheet metal; deep drawing; Tool steel; surface preparation; Friction; Materialteknik; Materials Engineering;

    Abstract : In sheet metal forming operations the life length of the production equipment islargely dependent on the wear of the tools that are in direct contact with the sheet.One form of adhesive wear where some sheet material gets transferred to the tool, alsoknown as galling, is the most common cause of tool failure.

  4. 9. Inclusion Characteristics and Their Link to Tool wear in Metal Cutting of Clean Steels Suitable for Automotive Applications

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Niclas Ånmark; KTH.; [2015]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Tool wear; PCBN; Machinability; Steel; Non-metallic inclusions; Materials Science and Engineering; Teknisk materialvetenskap;

    Abstract : This thesis covers some aspects of hard part turning of carburised steels using a poly‑crystalline cubic boron nitride (PCBN) cutting tool during fine machining. The emphasis is on the influence of the steel cleanliness and the characteristics of non‑metallic inclusions in the workpiece on the active wear mechanisms of the cutting tool. READ MORE

  5. 10. Steel characteristics and their link to chip breaking and tool wear in metal cutting

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Niclas Ånmark; KTH.; [2016]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; machinability; steel; non-metallic inclusions; skärbarhet; stål; icke-metalliska inneslutningar; Materials Science and Engineering; Teknisk materialvetenskap;

    Abstract : The vision of this thesis is to study how it is possible to obtain optimised workpieces during metal cutting processes in industry. Specifically, the work is aimed to increase the understanding between the steel characteristics and their link to the chip breaking and tool wear during metal cutting. READ MORE
