1. 1. 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

3. 2. Tool steel for tool holder applications : microstructure and mechanical properties

   Författare :Anna Medvedeva; Jens Bergström; Birger Karlsson; Karlstads universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tool steel; tool holder; microstructure; mechanical properties; machinability; Materials science; Teknisk materialvetenskap;

   Sammanfattning : Large improvements in cutting tool design and technology, including the application of advanced surface engineering treatments on the cemented carbide insert, have been achieved in the last decades to enhance tool performance. However, the problem of improving the tool body material is not adequately studied. LÄS MER

4. 3. Tolerance Analysis Framework for Cutting Tool Interface Design

   Författare :Soner Camuz; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Variation simulation; reliability-based optimization; tolerance analysis; cutting tool interface design; geometry assurance;

   Sammanfattning : Tolerance analysis of cutting tool interface designs is a field with many opportunities for further development of existing methodologies. Cutting tool interface designs require multiple contacting surfaces, allocating the stress generated from the cutting forces, to avoid excessive deformation of the interface. LÄS MER

5. 4. Sheet metal trimming dies – characterisation methods of geometry and surface topography and the influence on wear

   Författare :Per Jonsson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; finish milling; wear measurement; functional surface; trimming dies; scale-sensitive fractal analysis; surface roughness; polishing; surface characterisation; high strength steel; tool wear;

   Sammanfattning : In recent years, the life cycle of car models has decreased from 7 to 5 years and the volume sizes are becoming shorter in the automotive industry. The increasing number of car models introduced to the market means that a fewer number of parts must pay the costs for the tool/die design and manufacturing. LÄS MER

7. 5. Rule by Association : Japan in the Global Trans-Imperial Culture, 1868-1912

   Författare :John Hennessey; Hans Hägerdal; Alexis Dudden; Linnéuniversitetet; []
   Nyckelord :HUMANIORA; HUMANITIES; global trans-imperial culture; association; assimilation; Hokkaido; Taiwan; expositions; Japanese colonialism; Japanese Empire; colonial history; colonial administration; Historia; History;

   Sammanfattning : Criticizing one-empire approaches, calls to apply much-needed transnational perspectives and methodologies to colonial history have recently emerged. This groundbreaking scholarship has already revealed that the competition between different European empires after 1850 has typically been overemphasized; in fact, a transnational perspective reveals extensive cooperation between the “great powers” of the age, along with myriad examples of exchanges and transfers of colonial knowledge.
