Loose abrasive edge wear effects and final surface topography in conventional grinding machines

Applying Cordero-Davila's edge ring pressure increase to upper disk kinematics equations has led to excellent agreement between theoretical loose abrasive wear computer simulations and their experimental counterparts. Experiments to verify Cordero's ring equations over long grinding periods, up to 40min, and their computer simulations are presented in detail. These experiments led to a new improved version of Kumanin's loose abrasive wear equation. Maximum wear rate and final topography errors, between theory and experiment, were slightly larger than instrumental uncertainty. Now it became possible to compute exact pressure, relative speed and wear, at any contacting point pair and over the entire upper free disk surface.
