“…In our previous work, we studied, in the same process configuration, the link between grits' morphology, the surface finish of belt-finished workpieces, and the physical mechanisms which govern their wear performance [9]. We found that a coating with slanted grits had the advantage to ensure a good clipping of roughness profile while preserving valleys depth and thus, preserving the retention capacity of the surface roughness.…”

Advanced belt finishing process is remarkably simple and inexpensive. The principle of operation is simple: pressure-locked shoes platens circumferentially press an abrasive coated belt on a rotating workpiece. This abrasive machining process reduces significantly surface irregularities subsequently improving geometrical quality and increasing wear resistance and fatigue life. It is therefore extensively used in automotive industry to superfinish crankshaft journals. However, the major industrial issue about this manufacturing process is its efficiency and robustness. One of the most promising ways to solve this issue is to control the distribution and morphology of the abrasive grits. Recently a new generation of abrasive belts coated with structured and shaped agglomerate grits has been commercially available. These structured coated belts with mastered cutting edge orientations promise to be more efficient as they have a better wear resistance compared to the traditional coated abrasive belt. Therefore, this work aims to discuss these assumptions and to establish the link between three structured coated belts, the surface finishes and the physical mechanisms which govern their wear performances. In particular a parametric study, based on the cycle time and the rotation speed, is lead in order to analyze the potential of each structure in terms of surface roughness improvement, wear resistance and consumed energy. The experimental results have demonstrated that, depending on the abrasive structure considered and for a same number of revolutions, modifying the cycle time or the rotation speed can lead to different surface finishes and belt's wear.

Structuring Surfaces by Microfinishing Using Defined Abrasive Belts

Microfinishing, also known as superfinishing or short-stroke honing, is a commonly used process for generating technical surfaces focusing on tribological applications. Due to microfinishing processes high surface qualities are manufacturable regarding the surface roughness and bearing area ratio. While the required characteristics for tribological loaded workpieces are changing with their rising significance, the surface structuring is becoming more and more important. With the use of defined abrasive belts, the possibilities of surface structuring by microfinishing are enhanced. The possibilities and challenges concerning surface structuring by microfinishing applying defined abrasive belts are described in this research study. Therefore, a geometrical-kinematic simulation is used to predict the theoretical structures generated by microfinishing, while in experimental investigations the influences of kinematic parameters and a multi-stage process sequence are considered.

“…Then, a multiscale representation of the topographic profile that better reflects the variations in the process or the intended function of the component is obtained. Existing literatures in surface metrology show various purposes of the application of this approach such as process monitoring [11,13,24] and the identification of abrasive mechanisms activated during the finishing process [9,14]. Figure 1 illustrates the influence of choosing the mother wavelet function on the scale and amplitude of the detected surface features.…”

“…To take into account such multiscale behavior, processing techniques that decompose the observed data at different scales are necessary [8]. Various harmonic and morphological approaches were proposed in the literature [10] such as pass band filtering, discrete [11,12] and continuous [9,13] wavelet decomposition, the evaluation length variations method [14,15], and modal decomposition [16].…”

Multiscale surface characterization is a powerful tool that is used for process monitoring, surface quality control, and manufacturing optimization by establishing a link between process variables and functional performances. The multiscale decomposition approach using continuous and discrete wavelets is widely applied to take into account scales dependency. However, the optimal choice of the analysis wavelet function and the number of decomposition level is still a big issue. In this article, the artificial neural network theory was combined with the wavelet concept and was optimized based on the genetic algorithm to identify the relevant wavelet function for multiscale characterization of abraded surface topographies. Then, an extensive wavelet function library was developed and the proposed algorithm was applied to topographic data obtained from various abrasive finishing processes. The results show the pertinence of this approach to select the relevant wavelet, and a universal relevant wavelet function for abraded surface characterization was determined.
