METHOD OF THE ABRASIVE PROCESSING Russian patent published in 1995 - IPC

FIELD: mechanical engineering. SUBSTANCE: method includes operations of polishing and burnishing. The burnishing is carried out in two stages. The standard pressure P₂ in the processing zone and the velocity V₂ of the tool shifting at the second stage are determined on condition that where P₁ is the value of the standard pressure at the first stage of burnishing, ρ is the edge radius of the abrasive grain of the tool, h₁ is the depth of forcing the abrasive grain at the first stage of burnishing, V₁ is the speed of the tool shifting at the first stage of burnishing, f_b is the burnishing factor at the first stage, f_f in the friction coefficient at the second stage of burnishing. EFFECT: enhanced quality. 4 dwg
