2. 1. Theoretical and experimental studies of a single tooth milling process

   Author : Mathias Werner; Cornel Mihai Nicolescu; Lars Nyborg; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hobbing; single tooth milling test; TiN; High speed Steel HSS ; wear mechanisms; cutting force; cutting edge preparation; tool surface preparation; FEM cutting model;

   Abstract : The industrial development of metal cutting processes in gear manufacturing aims at continuously increasing productivity, including increased tool reliability. Basically, the parameters that have an influence on the cutting processes should be known and possible to control.Gear manufacturing is highly important for the automotive industry. READ MORE

4. 2. Mechanisms of Plastic Deformation of Cemented Carbide and Cermet Cutting Tools

   Author : Gustaf Östberg; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SEM; cermets; TEM; plastic deformation; ab initio calculations; EFTEM; APFIM; FIB; cemented carbides; EBSD;

   Abstract : In this thesis, the physical mechanisms acting during plastic deformation of hardmetals used in metal cutting applications have been investigated. Microstructural and microanalytical studies have been performed on cemented carbides as well as cermet materials. READ MORE

5. 3. Implementation and development of serial synchrotron crystallography at MAX IV

   Author : Bjelčić Monika; Göteborgs universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; ssx; time-resolved; crystallography; MAX IV LAboratory;

   Abstract : Over the past decade, remarkable advancements in femtosecond X-ray free-electron lasers (XFELs) have brought about a profound transformation in structural biology. These XFELs have opened up exciting opportunities for conducting high-time resolution, room-temperature studies on protein structures and dynamics. READ MORE

6. 4. Grinding effects on surface integrity, flexural strength and contact damage resistance of coated hardmetals

   Author : Jing Yang; Magnus Odén; Luis Llanes; Andrew Gant; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : The tribological and mechanical behavior of coated tools depends not only on intrinsic properties of the deposited film but also on substrate surface and subsurface properties – such as topography and residual stress state – as well as on interface adhesion strength. It is particularly true in the case of coated tools based on WC-Co cemented carbides (backbone materials of the tool manufacturing industry, and simply referred to as hardmetals in practice) as substrates.
