Modeling the wetting behavior of grinding wheels

Abstract Helical flute grinding is an important process step in the manufacturing of cylindrical cemented carbide tools where use cooling lubricants a defining factor determining performance. Finding optimal parameters and conditions for efficient lubricant essential reducing energy consumption controlling properties boundary zone like residual stresses. Any mathematical model describing interactions between wheel, workpiece during has to account complex microstructure wheel; however, this renders identification slip or heat exchange coefficients numerically prohibitively expensive. In paper, results from oil droplet experiments are compared with simulation wetting behavior wheels. More specifically, finite element simulations thin-film equation used identify different wheel specifications (grain size, bonding structure, status). Our show that both grain size have influence on behavior. The we identified fluid-microstructure will be effectively those more 3D fluid-dynamic via Beavers-Joseph condition.
