2. 1. Polishability of tool steels : Characterisation of high gloss polished tool steels

   Author : Sabina Rebeggiani; Olaf Dambon; Högskolan i Halmstad; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tool steels; surface characterisation; polishability; 3D parameters; high gloss polishing; Surface engineering; Ytbehandlingsteknik;

   Abstract : The manufacturing of plastic components, like a majority of other mass produced discrete parts, require well designed dies and moulds. Complex geometries and increasing demands on final surface appearance, which is strongly connected to the quality impression, are pushing for high demands on mould-makers and polishers as well as steel producers.

4. 2. On Polishability of Tool Steels

   Author : Sabina Rebeggiani; Bengt-Göran Rosén; Liam Blunt; Högskolan i Halmstad; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tool steels; polishability; surface characterisation; surface texture parameters; high gloss polishing; injection moulding;

   Abstract : One of the world’s fastest growing industries is the plastic industry. Today’s ever increasing demands of high quality products, shorter lead times and reduced costs push development and research forwards. READ MORE

5. 3. On tool steel, surface preparation, contact geometry and wear in sheet metal forming

   Author : Fredrik W. Lindvall; Jens Bergström; Staffan Jacobson; Karlstads universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wear; Galling; sheet metal; deep drawing; Tool steel; surface preparation; Friction; Materialteknik; Materials Engineering;

   Abstract : In sheet metal forming operations the life length of the production equipment islargely dependent on the wear of the tools that are in direct contact with the sheet.One form of adhesive wear where some sheet material gets transferred to the tool, alsoknown as galling, is the most common cause of tool failure.

6. 4. On cutting tool resource management

   Author : Ana Esther Bonilla Hernández; Tomas Beno; Claes Fredriksson; Leonardo De Chiffre; Högskolan Väst; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CAM programming; Cutting data; Lean; Manufacturing; Material Removal Rate; Optimization; Tool life; Tool utilization; Tool wear; Sustainability; Production Technology; Produktionsteknik; Manufacturing and materials engineering; Produktions- och materialteknik;

   Abstract : The search for increased productivity and cost reduction in machining can be interpreted as desire to increase the Material Removal Rate, , and maximize the cutting tool utilization. The CNC process is complex and involves numerous constraints and parameters; ranging from tolerances to machinability. READ MORE

7. 5. On a novel technique for preparation and analysis of the implant surface and its interface to bone

   Author : Anders Palmquist; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Focused Ion Beam FIB ; Transmission electron microscopy TEM ; Scanning electron microscopy SEM ; osseointegration; rabbit; human; titanium; titanium alloy; surface analysis; bone-implant interface analysis; ultrastucture; surface modification; laser;

   Abstract : The ultrastructural and biomechanical properties of the bone-implant interface are important factors for implant performance. For further understanding of the osseointegration process novel tools enabling analysis of the intact interface in high resolution is needed, preferably combined with histology and biomechanical tests.
