2. 1. Analysis of Structural Dynamic Properties and Active Vibration Control Concerning Machine Tools and a Turbine Application

   Author : Henrik Åkesson; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Active Vibration Control; Structural dynamics; Nonlinearities; Turning; Milling;

   Abstract : Vibration in metal cutting is a common problem in the manufacturing industry, especially when long and slender tool holders or boring bars are involved in the manufacturing process. Vibration has a detrimental effect on machining. In particular the surface finish is likely to suffer, but tool life is also most likely to be reduced. READ MORE

4. 2. Methods for Characterisation of Pressing Die Surfaces

   Author : Johan C Berglund; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; finish milling; scale-sensitive fractal analysis; surface characterisation; polishing; functional correlation; : pressing dies; functional filtration; surface roughness; functional surface;

   Abstract : Design and manufacture of dies and moulds is a critical aspect of many production systems since the manufacturing and try-out of new dies and moulds often is essential in determining the lead-time and quality of a new production system. In the automotive industry, many new car models are introduced each year and for each of these models, a new set of pressing dies has to be designed and manufactured. READ MORE

5. 3. Machinability Testing of Materials in Metal Cutting with Focus on Compacted Graphite Iron and Cutting Fluids

   Author : Varun Nayyar; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; UTS.; Boring; Drilling; Cutting Fluid; Turning; Milling; Force; Wear; Force; Torque; Compressed air; CGI; Hardness; Tool Life; Material Properties; Chip Microstructure; Tapping;

   Abstract : Due to the stringent demands for lower emission from trucks require better mechanical properties of the material to be used in the engines. Better efficiency necessitates higher peak pressure in the engines and for traditionally used material, Flake Graphite Iron (FGI), the mechanical properties starts to reach the limit of what the material can withstand.

6. 4. Characterisation of Functional Pressing Die Surfaces

   Author : Johan C Berglund; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; functional correlation; functional surface; functional filtration; pressing die; multi-scale analysis; characterisation; finish milling; texture anisotropy; polishing; surface topography;

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

   Author : Per Jonsson; Chalmers tekniska högskola; []
   Keywords : 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;

   Abstract : 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. READ MORE
