“…The established dependences of filament wear on cutting modes qualitatively coincide with the results of studies for similar tools considering the wear process from the point of view of tribology [13,14,15]. The results of the experiments confirm the studies [12,17], in which it was substantiated that wear depends on thermal processes in the machining zone, the material being processed, interference and cutting speed.…”

“…One of the effective ways to control the accuracy and quality of machining parts using PABT is to build models that allow evaluating the influence of process parameters on the characteristics of accuracy and quality of surfaces machined. In [15], the effectiveness of elastic polymer-abrasive wheels when rounding edges has been proven. The research showed the influence of cutting speed, tool deformation and feed along the edge on the quality of the machined edge and the process productivity.…”

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.

“…Most literary sources study the possibilities of PAB in terms of achieving a minimum roughness and determining rational modes when machining surfaces and edges [1,8]. The use of PABs for polishing certain materials [9,10], as well as parts whose surface requires special treatment [11], is also being considered.…”

“…The abrasive brush tool is used for a wide range of finishing machining of parts and structures: rounding sharp edges, removing burrs, and polishing surfaces [1,2]. In some cases, polymer-abrasive brushes (PABs) replace outdated, less productive, non-environmental-friendly methods [3,4].…”
