  2. 26. High Pressure Jet Assistance in Steel Turning

    Author : Patrik Dahlman; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Jet Assistance; Tool Life; Chip Control; Turning; Ultra High Pressure Cooling; Jet Momentum;

    Abstract : Steel turning is one of the most common industrial processes today. It is a very old process, where a lot of improvements and optimisations have been done throughout history. But, the struggle for further cost reductions pushes the process development into new areas. READ MORE

  4. 27. Very high cycle fatigue of tool steels

    Author : Vitaliy Kazymyrovych; Jens Bergström; Arne Melander; Karlstads universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fatigue; crack growth; ultrasonic testing; tool steels; inclusions; Materialteknik; Materials Engineering;

    Abstract : An increasing number of engineering components are expected to have fatigue life in the range of 107 - 1010 load cycles. Some examples of such components are found in airplanes, automobiles and high speed trains. READ MORE

  5. 28. High Performance Manufacture of Sintered Steel – Critical Aspects of Tooling Performance and Sintered Microstructure

    Author : Sepehr Hatami; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Tool Steels; Chromium Alloyed Steel; Modelling; Process Selection; Sinter-Hardening; Atmosphere; Microstructure; Galling; Pressing Dies; Wear;

    Abstract : Steel is the dominant material for the production of structural parts. By means of powder metallurgy (PM) processing, manufacturers have been able to manufacture steel parts with appreciable dimensional accuracy and desirable mechanical properties. READ MORE

  6. 29. Wear of coated and uncoated PCBN cutting tool used in turning and milling
