Analytical determination of conditions of reduction of surface roughness at abrasive polishing

A mathematical model for determining the surface roughness in abrasive polishing conditions is established with the aim of lowering it. It consists in the realization of ultimate shear value of the ratio of thickness to radius of rounding the cutting edge of the abrasive grains, whereby the cutting process ( chip formation ), the process proceeds to the plastic deformation of the material without separating chips. It was found that the limiting value of the slice thickness to the radius of the rounding of the cutting edge of the abrasive grain were determined friction abrasive grain with the material being processed
