“…In general, longer filaments are less rigid and used for achieving finer surface finishes while the shorter filament lengths have a greater stiffness and are used on hard materials or when more aggressive material removal rates are desired [6]. It has been found that abrasive filament tools can generate surface textures that range from a Ra of 13 μm, for tools made of larger-diameter steel wire, to a Ra of 0.40 μm for tools that employ fine grit nylon/ abrasive fibers [7]. However, the exact correlation between texture parameters and the corresponding filament chosen for the polishing operation is complex and, therefore, experimentation is often required in order to obtain the desired results [7].…”

“…Stango and colleges have identified three distinct regions within the contact zone for wheel-type filament tools, which provide general insight into the material removal process for orthogonal polishing with filament tools [7]. Region I is the initial contact zone where the bristle makes first contact with the workpiece.…”

“…The contact mechanics for disk-type tools differ from that of wheel-type tools [7]. Once the disk-type tool is in full contact with the workpiece, and the workpiece is wider than the tool, the filaments remain in constant contact with the surface and exert even cutting forces.…”

“…As the tool rotates and translates across the surface of the workpiece the abrasive particles embedded within the nylon are exposed along the exterior of each filament, as shown in Fig. 5, and act as multiple small cutting edges to polish the surface [7].…”

In order to expand the regional production of machine tools which utilize precision machined sliding guideways, cubic boron nitride (CBN) hard milling may be implemented as an alternative finish process instead of conventional surface grinding. While higher material removal rates can be achieved with a milling strategy, the use of a defined cutting edge leads to surfaces with asperities. These sharp peaks quickly wear down during sliding contact, resulting in unacceptable changes in the load bearing surface of the guide. Therefore, a post process to milling must be implemented to mitigate these features. This paper investigates the use of a spindle mounted abrasive disk filament tool for producing a functional surface similar to the ground surfaces. The optimal process parameters were investigated using 2D profile measurements, followed by comparison using areal analysis of ground, milled, and polished surfaces. It was found that polishing reduces both the height and volume of asperities on the milled surface, leading to contact characteristics which were more similar to those of the conventional ground surfaces currently used for sliding guideways.

“…remove undesirable burrs resulting from the milling, etc., or the changes in the condition of the edges of the objects in a form of rounding, chamfering, blunting [1,8,9,11]. Taking into account the fact that most elements after machining have burrs, the application of brushes in the machining centres creates a possibility of processing involving the removal of burrs directly after machining without dismantling the parts from the area of the treatment machine.…”

Brushing is one of the mechanical processing methods of the surface, which involves the effect of a rotating tool on the workpiece. There are many design solutions for brushes, and the basic division is related to the arrangement of working elements and divides the processing into cylindrical and front brush. The more detailed division concerns the materials used to fill brushes, which can be natural, artificial, composite in a form of sunken abrasive grains into plastic fibers. In addition, individual fibers can be found in a simple, crimped or knot form. Brushes with knot fibers are more rigid and are thus used for more aggressive applications. Fibers can also be characterized by chemical and temperature resistance.By analysing the brushing process and the effects obtained after this treatment, it is difficult to clearly identify this process into a particular surface treatment method. At the intersection of the cylindrical surface of the fibre with the front one, an edge is formed, which can be treated as the cutting edge of the tool, which is present in typical machining tools. While brushing, the material removal nature of this process can be seen, however, the brushing products are comparable to those produced in abrasive processing. In turn, taking into account the kinematics of the treatment, individual fibres, while hitting the surface, perform the burnishing task analogous to the dynamic burnishing process [13,14]. The study results of the hardening of the surface layer and its favourable properties are presented in [2]. The study results on the increase of fatigue strength due to the favourable effect of brushing on the state of stresses and the hardening of the surface layer were presented. Considering various ways of impact of the brushing process on the surface and the surface layer, the brushing treatment can be treated as one of the hybrid processing methods. In practice, brushing is used to change the topography of the surface, remove corrosion products, paint coatings. The change of topography of the surface may be related to the decorative aspect or it may affect the surface development, the increase of free surface energy, which is of key importance in adhesion material bonding [4]. However, the most beneficial effects can be obtained by using the brush-cleaning treatment to Research Article ABSTRACT Because of its advantages, brushing processing has many uses. The main ones include the removal of corrosion products, surface cleaning, deburring and shaping the properties of the surface layer. The intensity of these processes depends on the degree of impact of brush fibres on the work surface. In the case of tools, in which the resilient fibres are the working elements, forces in the brushing process, apart from the machining parameters, depend on the characteristics and overall dimensions of individual fibres. The paper presents the results of studies of the influence of technological parameters and type of fibres on the radial force in the brushing process. THE EFFECT OF MACHINING CONDITIONS...
