Theory of Formation of Edge’s Surface Roughness Finished by Radial Polymer-Abrasive Brushes

Abstract

Formation of roughness during treatment by polymer-abrasive brushes occurred as a result of interaction of cutting micro-relief with processed surface. The cutting micro-relief of abrasive instrument is described in the form of random process with normal distributional law. When calculation of roughness, the depths of penetration of cutting lugs in processed material as well as regularity of changing of radial radius of rounding of peaks of cutting lugs from modes of treatment are taken into consideration. Set are relations of roughness of processed edge from modes of treatment (deformations of instrument, cutting velocities, feeding) as well as from constituent cutting force. It is proved that usage of polymer-abrasive brushes for rounding of edges faces all requirements of aviation industry on roughness of processed edges.

Model of Influence of the Machined Material Properties on Wear of the Polymeric-Abrasive Tool Filaments

“…Modern scientific literature gives information about technologies of the manufacturing polymer-abrasive brush tools and their application. There are also studies in which the dependence of the surface quality on the processing modes, the force effect of the tool on the part and the temperature field in the tool-part zone were determined [8,9,10]. There are also publications that explore the possibilities of achieving high processing performance and their use for polishing certain materials or parts with special surface requirements [5].…”
