  1. 1. Surface integrity on post processed alloy 718 after nonconventional machining

    Författare :Jonas Holmberg; Tomas Beno; Anders Wretland; Johan Berglund; Mikael Olsson; RISE; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Alloy 718; Non-conventional machining; post processing; surface integrity; Microstructure; Residual stress; Electron back scattering diffraction; Material removal rate; Manufacturing; Surface and Joining Technology; Bearbetnings-; yt- och fogningsteknik; Production Technology; Produktionsteknik; Manufacturing and materials engineering; Produktions- och materialteknik;

    Sammanfattning : There is a strong industrial driving force to find alternative production technologies in order to make the production of aero engine components of superalloys even more efficient than it is today. Introducing new and nonconventional machining technologies allows taking a giant leap to increase the material removal rate and thereby drastically increase the productivity. LÄS MER

  2. 2. Machinability of Single-phase Materials : Surface integrity and tool wear analysis

    Författare :Mike Olsson; Industriell Produktion; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; Machinability; Niobium; Tungsten; Oxygen-free copper; Surface integrity; Tool wear;

    Sammanfattning : The quality and performance of products are particularly important in sectors such as research facilities and in the nuclear, military and space industries. These sectors make use of high-performance materials that are uncommon in other contexts and therefore place high requirements on personnel, machines and tools. LÄS MER

  3. 3. Surface Integrity Characterization of Gears with respect to Running-in

    Författare :Dinesh Mallipeddi; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; micropitting; surface asperities; running-in; surface roughness; residual stresses; Gears; surface chemistry;

    Sammanfattning : A gearbox with gears of different sizes is part of a vehicle transmission system that plays an important part in transmitting the engine power to the wheels. The efficient energy transmission highly relies on the performance of gears. Together, the mesh efficiency and durability determines the gear performance. LÄS MER

  4. 4. Surface integrity and corrosion behavior of stainless steels after grinding operations

    Författare :Nian Zhou; Rachell Pettersson; Ru Lin Peng; Stuart Lyon; Högskolan Dalarna; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; stainless steel; stress corrosion cracking; surface integrity; grinding; residual stress; Steel Forming and Surface Engineering; Stålformning och ytteknik;

    Sammanfattning : Stainless steels are widely used in applications where both the mechanical properties of steels and high corrosion resistance are required. There is continuous research to enable stainless steel components to be produced in a more economical way and be used in more harsh environments. LÄS MER

  5. 5. High volumetric machining strategies for superalloy gasturbine components : Comparing conventional and nonconventional machining methods for efficient manufacturing

    Författare :Jonas Holmberg; Johan Berglund; Anders Wretland; Tomas Beno; Joel Andersson; Sten Johansson; RISE; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Alloy 718; High volumetric machining; Conventional and Nonconventional machining; Material removal rate; Post processing; surface integrity; Residual stress; Microstructure; Deformation; Manufacturing; Surface and Joining Technology; Bearbetnings-; yt- och fogningsteknik; Production Technology; Produktionsteknik;

    Sammanfattning : There is a strong industrial driving force to find alternative manufacturing technologies in order to make the production of aero engine components of superalloys even more efficient than it is today. Introducing new and nonconventional machining technologies, as well as enhanced utilisation of today's high volumetric manufacturing, allows taking a leap to increase the material removal rate and the productivity.
