ON THE COMPARISON OF CONTACT AND NON-CONTACT EVALUATIONS OF A MACHINED SURFACE

Miroslav Piska, Jitka Metelkova
Keywords: statistical analysis | comparative study | 3D optical methods | stylus measurement | surface metrology | surface roughness

Surface integrity of machined parts plays a crucial role in their use, efficiency, comfort and safety. The trend of more effective and low-consumption products forces the producers to reduce weight and dimensions of the industrial parts so the requirements on the machined surface quality evaluation is more important from many aspects. The booming trend in optical non-contact techniques seems to b (…)

STUDY OF GREASE BEHAVIOUR IN A STARVED ELASTOHYDRODYNAMICALLY LUBRICATED CONTACT

Petr Svoboda, David Kostal, Jiri Kunak, Ivan Krupka
Keywords: EHD lubrication | starvation | grease

This paper is an experimental study of grease lubrication in a starved elastohydrodynamic lubricated (EHL) contact. Lubricating film thickness is measured with tribological experimental device ball-on-disc using optical interferometry and high speed camera. The lubricants used were commercial greases with a various kinematic viscosities, additives and thickeners formulated for low and high-speed (…)
