Evaluation of methods for measuring tool-chip contact length in wet machining using different approaches (microtextured tool, in-situ visualization and restricted contact tool)

Ellersiek, Lars; Menze, Christian; Sauer, Florian; Denkena, Berend; Möhring, Hans-Christian; Schulze, Volker (Berlin, Heidelberg : Springer, 2022)

The contact length is one of the most important factors to evaluate the chip formation process and the mechanical loads in metal cutting. Over the years, several methods to identify the contact length were developed. ...
Influence of metal working fluid on chip formation and mechanical loads in orthogonal cutting

Denkena, Berend; Krödel, Alexander; Ellersiek, Lars (London : Springer, 2022)

Metal working fluids are used in machining processes of many hard-to-cut materials to increase tool life and productivity. Thereby, the metal working fluids act on the thermal and on the mechanical loads of the tool. The ...
Investigation of pressing and ejection performance of friction-reducing powder-compaction tool coatings

Behrens, Bernd-Arno; Brunotte, Kai; Petersen, Tom; Bohr, Dieter ([Ostrava-Zabreh] : Tanger Ltd., 2021)

Pressing in dies followed by sintering is the most commonly used process for shaping metal powders into components. The mechanical properties (e.g. tensile and fatigue strength) of the final sintered component depend on ...
Microscopic investigations into lubricated friction pairs in synchronizers

Poll, G.; Neudörfer, S.; Skubacz, T. (London : SAGE Publications Ltd., 2008)

An essential component of manually operated vehicle transmissions is the synchronising device. Synchronizers have the task of minimizing the speed difference between the shifted gearwheel and the shaft by means of frictional ...
Oscillating rolling element bearings: A review of tribotesting and analysis approaches

de la Presilla, Román; Wandel, Sebastian; Stammler, Matthias; Grebe, Markus; Poll, Gerhard; Glavatskih, Sergei (Amsterdam [u.a.] : Elsevier Science, 2023)

Rolling element bearings, when subjected to small oscillating movements or vibrations, run the risk of being damaged by mechanisms such as Standstill Marks and False Brinelling. Damages resulting from these phenomena can ...
Physical properties of boundary layers in angular contact ball bearings lubricated with greases containing polymers

Gatzen, M.M.; Pape, F.; Poll, G.W.G. (London : SAGE Publications Ltd., 2009)

This article describes the effect of polymer additives in lithium greases on performance and boundary layers of high-speed angular contact ball bearings. High-speed test rigs were used to run grease life tests utilizing ...
