“…The frequency of rotations was controlled by a mechanical tachometer. The machined sample of steel 20 with a roughness of Ra3,2 was fixed at control device 6 [23]. It includes damper 11 to prevent excessive rocking of the top of the device, and inductive sensor 8, which measures the amount of displacement of the support arm with the sample.…”

“…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].…”

For polymer-abrasive brush tools (PABT) working on CNC machines it is necessary to correct their wear constantly, since it is much higher compared to the wear of metal tools. Based on the dependence of tool wear on machining parameters for various materials, it is necessary to study the influence of the physical and mechanical properties of the material machined. The purpose of the paper is to study the process of finishing the surfaces of parts made of materials of different types with PABT. The analysis of dimensional wear of disc PABTs during the polishing various materials with certain physical and mechanical properties is provided in the article. The polishing was carried out in rational modes that ensure high quality and productivity of surface treatment. The similarity theory and dimensional analysis were used to assess the influence of the properties of the material machined on the intensity of PABT filament wear. To calculate it, dimensionless complexes were established, which take into account the physical and mechanical properties of the machined materials and evaluate their resistance to the penetration of abrasive grains, the ability of the material to absorb mechanical energy in the process of deformation and destruction under the impact of PABT filaments. The developed model was created for the first time. It made it possible to solve the problem of predicting the degree of dimensional wear of the disc PABT when polishing various materials, including difficult-to-machine ones. Prediction of the intensity of PABT filaments wear allows timely correction of the tool position during machining on CNC machines to ensure a constant pressing of the PABT to the surface being machined. The obtained Км material coefficient takes into account the influence of the physical and mechanical properties of the machined material and then estimates the intensity of PABT filaments wear. The KМ material coefficient can also be used to assess the PABT life and calculate the economic efficiency of the parts finishing treatment at the stage of technology development and the selection of polishing tools.
