“…The brushing process is a metal-cutting process used for the grinding of metallic surfaces with the help of brushes. Its main applications are the deburring of precision components [9], the structuring of decorative surfaces of glass [26], and the functional surface preparation of metals for subsequent process steps of joining [35]. Common to all these applications is that the brushing process functions as a finishing process for components with a high inherent added value.…”

“…In principle, such prediction models can be obtained from a comprehensive simulation of the brushing process [38], [26]. Such simulation-based models are expensive and complex because -in addition to the many process parameters mentioned above -the dynamic behavior of the tool has to be broken down to the filaments and microscopically to the individual grain in engagement.…”

“…Mathai et al investigated the brush deburring of Nitinol foil and found that the burr removal can be divided into two stages: fatigue fracture and crack formation [12,13]. Novotný et al presented the novel process of frosted glass using an abrasive filament brush and provided a good quality surface [14]. The above foregoing sources mainly focused on the surface morphology changes after brush grinding and do not clarify the influence of the process parameters on the brush force and material removal rate.…”

Abrasive filament brushes have been widely used in surface processes for a wide range of applications, including blending, edge-radiusing, and polishing. However, the associated brush mechanics of material removal is still not clear. In order to analyze the brush grinding of aluminium alloy, this paper constructed a kinematic model of a single filament, simulated the scratch process of a single abrasive grain, and investigated the brush force and material removal based on the finite element approach. The simulated result shows that the brush grinding can be changed from elastic–plastic deformation to chip formation when increasing the brush speed to 1000 r/min. The normal and tangential forces increase linearly and quadratically with the increase in the rotation speed (500–5000 r/min), respectively, and increase linearly with the increase in the penetration depth (0.1–1 mm), which is consistent with the experiment results. In addition, the amount of material removal initially increases with the increase in penetration depth, and then decreases. This paper provides a new approach to understanding the process of material removal and is helpful for the selection of reasonable brush parameters in the intelligent grinding control application.

“…10 For example, the studies on the road sweeping brush 11 have developed the methodology of modeling brush deformation to analyze brush contact geometry and contact force, and the results were further summarized into mathematical models, which were utilized in experiments and dynamics analysis. Novotný et al 12 present the novel elimination process for frosted flat glass that use a cylindrical brush with composite filaments, and provide a good quality surface. Uhlmann and Hoyer 13 carried out the surface finishing of zirconium dioxide with abrasive filament brush, and found that the grain size and the brushing velocity have a considerable influence on the surface quality of zirconium dioxide.…”

In the process of surface treatment, steel wire brush can not only efficiently remove surface contaminants, such as deteriorated paint film and rust, but also increase the adhesive strength. However, the associated brush mechanics of material removal is still not clear. In order to reveal the brush mechanics of material removal, this paper assumed the tip of steel wire were ball–cone shaped, constructed contact force model, and calculated the brush grinding force under different process conditions based on finite element approach. The simulated results show that the brush grinding can be changed from plastic plowing to chip formation when the penetration depth is increased to 10 μm, then changed from chip formation to plastic plowing when the inclination angle is increased to 30°, respectively. The simulated value of brush force rises with the increasing penetration depth and inclination angle, which was consistent with the experimentally obtained values, and the relative errors are within 9%. The quantity of material removal increases with the ascending of penetration depth, and decreases with the ascending of inclination angle. This paper provides guidance to understand the mechanics of material removal, predict the brush grinding force, and contribute well to an automatic grinding control application.
