The tool surface topography is often a key parameter in the tribological performance of modern metal forming tools. A new generation of multifunctional surfaces is achieved by combination of conventional tool manufacturing processes with a novel Robot Assisted Polishing process. This novel surface texturing method allows for a large degree of freedom in specifying surface characteristics and facilitates a high degree of reproducibility between samples surfaces. A series of strip reduction tests, equivalent to a metal forming ironing process, are conducted to benchmark the tribological performance of 15 generated tool surfaces. © 2012 CIRP. Source

Friction, lubrication, wear and other tribology related effects such as surface topography of tool and workpiece are important in many modern metal forming processes. In order to face these tribological challenges the subject of tool surface topography structuring has become Interesting. The following work demonstrates a method for generation of designed tool surface topographies by means of a novel Robot Assisted Polishing machine. Three tool rolls are polished using three different strategies and machine parameter settings. The resulting surfaces are qualified using 2D and 3D roughness measurement equipment. The strip reduction test is applied to assess the performance of the generated surfaces under challenging conditions. The results show a clear correlation between the tool surface topography and the resulting workpiece surface quality. © 2011 Wiley-VCH Verlag GmbH & Co. KGaA. Weinheim. Source
