1. 11. On the Effect of Grain Size and Hardness on the Machinability of Superalloys and Chip Deformation

   Författare :Stefan Olovsjö; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Superalloys; Microstructure; Burr; Machinability; Waspaloy; Chip microstructure; Tool wear; Alloy 718;

   Sammanfattning : Superalloys are used in applications such as gas turbines, steam power plants and nuclear power systems that require good high temperature properties and/or exceptional corrosion resistance. Superalloys are classified as materials that are “difficult to machine”. In production machining is a most commonly occurring procedure. LÄS MER

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

   Författare :Niclas Ånmark; Andrey Karasev; Pär Göran Jönsson; Thomas Björk; Jinming Zhou; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Tool wear; PCBN; Machinability; Steel; Non-metallic inclusions; Materials Science and Engineering; Teknisk materialvetenskap;

   Sammanfattning : 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. LÄS MER

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

   Författare :Niclas Ånmark; Andrey Karasev; Pär Göran Jönsson; Thomas Björk; Mikael Olsson; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; machinability; steel; non-metallic inclusions; skärbarhet; stål; icke-metalliska inneslutningar; Teknisk materialvetenskap; Materials Science and Engineering;

   Sammanfattning : 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. LÄS MER

7. 15. Performance of advanced tool steels for cutting tool bodies

   Författare :Anna Medvedeva; Jens Bergström; Pavel Krakhmalev; Staffan Gunnarsson; Volker Schulze; Karlstads universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tool steel; cutting tool body; fatigue strength; stress relaxation; machinability; high-temperature properties; microstructure; Materials science; Teknisk materialvetenskap; Materialteknik; Materials Engineering;

   Sammanfattning : 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. LÄS MER
