Abbott curves characteristics of turned surfaces
Petropoulos, G. P.; Torrance, A. A.; Pandazaras, C. N. (2003)Evaluation and modelling of bearing curves and bearing ratio parameters are of great importance in surface characterization and tribological functioning of engineering surfaces. The present investigation is focused upon ... -
Characterization and modelling of piston ring-cylinder tribosystem microtopography in lubricated contact
Pandazaras, C. N.; Petropoulos, G. P. (2000)A study of piston ring-cylinder tribological behaviour under mixed lubrication mode is usually based upon data regarding surface contact magnitudes, fluid film characteristics and resultant mixed friction forces. The present ... -
A computational estimation of the critical rotational speed for finite hydrodynamically lubricated journal bearings
Pandazaras, C. N.; Petropoulos, G. P. (2001)Presents theoretical results regarding the computational estimation of the critical rotational speed in smooth or of negligible roughness and waviness hydrodynamically lubricated journal bearings. Results were provided ... -
A computational study of hydrodynamically lubricated convex and concave journal bearings
Pandazaras, C. N.; Petropoulos, G. P. (2001)In the present study, computational data are presented regarding the tribological behaviour of convex and concave journal bearing configurations under hydrodynamic lubrication. In specific cases these results may improve ... -
Control of representative turned surface textures
Petropoulos, G. P.; Vaxevanidis, N. M.; Pandazaras, C. N.; Antoniadis, A. (2004)A method for characterizing machined surface textures corresponding to varying cutting conditions, which lead to differing profile shapes, is presented here. Through a proper multi-parameter analysis carried out on turned ... -
Morphological - Functional Aspects of Electro-Discharge Machined Surface Textures
Petropoulos, G. P.; Vaxevanidis, N. M.; Radovanovic, M.; Zoler, C. (2009)This study investigates a set of "non-common" surface topography parameters of Electro-Discharge Machined surfaces that give differing aspects of texture related to morphological characterization and possible tribological ... -
Multi-parameter identification and control of turned surface textures
Petropoulos, G. P.; Pandazaras, C. N.; Vaxevanidis, N. M.; Antoniadis, A. (2006)A method for characterizing turned surface textures corresponding to varying cutting variables leading to differing profile shape is presented with emphasis on a global view of turning machinability parameters. Through a ... -
Phenomenological investigation of cutting oils: Antifriction and antiwear behaviour at low contact temperatures
Pandazaras, C. N.; Ivkovic, B.; Petropoulos, G. P. (2001)The basic reason for the use of cutting fluids in machining processes is to increase cutting tool life and to decrease machining costs. An experimental simulation of tribological processes representing rear cutting tool ... -
