12. The effect of workpiece material and its microstructure on tool wear in metal cutting
Abstract : The aim of the present work is to promote the basic understanding of how the workpiece material and its microstructure affect the tool wear during metal cutting. To isolate the effect of the workpiece material, the tool material (uncoated cemented carbide) was kept constant while the workpiece was varied. READ MORE

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

15. High Temperature Wear Processes
Abstract : Moving machine assemblies are increasingly exposed to extreme operating conditions involving high temperatures owing to demands on higher power densities, high performance/efficiency and extreme environments. The changes in surface and near surface properties of contacting surfaces caused by exposure to high temperature and deformation govern the occurrence of friction, wear and material transfer of the tribological system.
