Research on removal function of fluid hydrodynamic fixed abrasive grinding

Fluid hydrodynamic fixed abrasive grinding (FHFAG) is now evolving into a promising finishing method underpinning the major advances across grinding and lapping sciences. While the advances have been startling, the key unmet challenge to date is the theoretical basis of removal function. Here, we approach this challenge by presenting a fully coupled flow deformation model. Given the separation function on microchannel from the grits fixed on the grinding pad, hydrodynamic pressure distribution with many dynamic pressure peaks and basic film thickness can be described theoretically. Combining with primary material removal mechanism the removal function of FHFAG was achieved. The experimental results showed a strong agreement with the prediction removal function model and its practicability has also been verified.
