Abstract
Novel composite system was developed, including real time force and temperature monitoring devices and minimum quantity lubrication (MQL) system. During MQL grinding, grinding force, temperature, blockage of a grinding wheel, surface roughness Sa and specific grinding energy are 0.9 N, 24 ℃, 15.49 %, 0.227 μm and 15.08 J/mm3 respectively, reducing 84.21 %, 51.81 %, 75.4 %, 88.4 % and 80 % correspondingly, compared with those of dry grinding. A motion model of single grain is proposed, and geometric contact arc length calculated is 44.76 μm. At optimal feed rate of 200 mm/min, the maximum and critical undeformed thicknesses of a chip are 0.05 and 2 μm, respectively. Infrared spectroscopy shows that crosslinking grid of cyanate ester was broken, and short-chain was formed on ground surface.
期刊介绍：
Tribology is the science of rubbing surfaces and contributes to every facet of our everyday life, from live cell friction to engine lubrication and seismology. As such tribology is truly multidisciplinary and this extraordinary breadth of scientific interest is reflected in the scope of Tribology International.
Tribology International seeks to publish original research papers of the highest scientific quality to provide an archival resource for scientists from all backgrounds. Written contributions are invited reporting experimental and modelling studies both in established areas of tribology and emerging fields. Scientific topics include the physics or chemistry of tribo-surfaces, bio-tribology, surface engineering and materials, contact mechanics, nano-tribology, lubricants and hydrodynamic lubrication.
