2. 16. On Characterization and Optimization of Surface Topography in Additive Manufacturing Processes

   Author : AMOGH VEDANTHA KRISHNA; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; areal surface texture parameters; additive manufacturing; power spectral density; vat-photopolymerization; laser-based Powder bed fusion; fused deposition modeling; profile parameters; feature-based characterization; and multiple regression.; scale-sensitive fractal analysis; surface metrology;

   Abstract : With its ability to construct components through the layer-by-layer deposition of material, Additive Manufacturing (AM), more commonly known as "3D printing", has revolutionized the manufacturing industries. Not only can AM produce complex lightweight designs, but it can also streamline the supply chain, allowing businesses to more quickly and easily meet customer demand. READ MORE

4. 17. 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

5. 18. On surface structure characterization and application on additive manufacturing

   Author : Olena Flys; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; surface texture parameters.; fused deposition modelling; power spectral density; coherence scanning interferometer; selective laser melting; Surface characterization;

   Abstract : Countless industrial applications over the past decades have indicated the increased need to relate surface texture to surface function. The fast-growing industry of additive manufacturing admits the surface roughness as one of the main challenges. READ MORE

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

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

   Abstract : 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. READ MORE

7. 20. On the bone response to different implant textures. A 3D analysis of roughness, wavelength and surface pattern of experimental implants

   Author : Carin Hallgren Höstner; Göteborgs universitet; []
