“…Then, this paper purposes the study of the multiscale effect of coated cutting tools on the NFRP surfaces after profile milling process. The tribo-energetic approach [28][29][30] was used to reveal the physical cutting mechanisms that are related to the tribological contributions of both coating and machining parameters. The multiscale approach [28,31,32] was hence used to identify the effect of the cutting contact conditions on the machined NFRP surface quality.…”

This work aims to investigate the tribological effects of coated tools on the surface finish of natural fiber reinforced plastics (NFRP) during profile milling process with particular emphasis on the natural fiber cutting mechanisms and tool wear. Both up-milling and downmilling configurations were considered. The cutting experiments were carried out on unidirectional flax fibers reinforced polypropylene resin (UDF/PP) using three different cutting tools. Uncoated tungsten carbide, titanium diboride (T i B 2 ) coated and diamond coated were used to conduct profile milling tests. Tribological cutting contacts were evaluated by measuring the specific cutting energy. Surface state was acquired by scanning electronic microscope (SEM) and optical microscope (OM). Surface topography was measured using 2D Surfascan stylus profilometer. Machined NFRP surface finish was characterized using standard and multiscale analysis based on wavelets transform.Results show that the cutting edge radius made by tool coating has a significant effect on surface finish. Natural fiber shearing is more efficient once the removed chip thickness exceeds the cutting edge radius value. Moreover, it had been demonstrated that the pertinent scales for surface finish analysis are between 50 µm and 1 mm which correspond to the multiscale fiber reinforcement structure. Furthermore, and unlike the uncoated tool, T i B 2 and diamond coatings allow a good wear resistance of the cutting tools against the tribological solicitations of flax composites machining.

“…The tribo-energetic approach [31,32] was used to identify the activated mechanisms during the tribological cutting contacts in machining and then establish the relationship between the fiber properties and induced-cut surface state of NFRP. The tensile stiffness and yield strength of each studied fiber are determined from mechanical properties of Each sample was polished at profile thickness of workpiece with the same grid size of sand paper before profile milling process.…”

AbstractRecently, natural fiber reinforced plastic (NFRP) materials are becoming a viable alternative to synthetic fiber in many industrial applications which not require high structural performances. However, machining of NFRP such as milling process is almost unavoidable operation to facilitate the parts assembly in addition to the finishing of final products. The present study thus focused on the influence of natural fiber types on tribological behavior during profile milling process. Three types of short natural fibers (bamboo, sisal and miscanthus) reinforced polypropylene (PP) composites are investigated. The quality of NFRP machined surface is quantified using a multi-scale analysis based on wavelets decomposition. The natural fiber effect related to the machined surface quality is hence identified at all scales from roughness to waviness. The Bamboo fibers reinforced plastics which exhibit high contact stiffness shows the smoother surface finish after machining. Therefore, the multiscale surface roughness is used as descriptor of natural fiber's influence on the machining mechanisms and to establish the cutting signature of NFRP materials.

“…7 demonstrates average material removal rate along the finishing duration. The curves of V s = 9.6 m/min in two figures have shown a stable cutting ability during the whole process when there is no adhesion wear [4,8,13]. Besides, it can also be noticed that increasing workpiece rotating speed is able to enhance material removal rate but not proportionally according to the results of Q w in the first 10 s. From Fig.…”

“…Nevertheless, for the cases with adhesion, material removal rate falls, especially for the case with a worse adhesion, which has been previously found in Refs. [8,13]. Finally, Q w becomes independent on belt feed rate in the cases where adhesion wear happens from the beginning.…”

Adhesion wear on abrasive belt sometimes occurs as an abnormal abrasion way because of an improper selecting on working conditions during the belt finishing. In this paper, the forming process of the adhesion wear and its effects on the finished surface is investigated through a series of experiments. The results reveal that the applied pressure and the belt feed rate are supposed to be the two sensitive variables for forming the adhesion wear. A certain amount of accumulated chips is a trigger to cause adhesion wear initially, and then, the sufficient heat accumulation becomes the main factor for the following adhesion wear. Thus, shortening the finishing duration, decreasing applied pressure, rotating speed and introducing cooling/lubrication system are recommended to avoid adhesion wear. The belt finishing process with adhesion presents a potential to further decrease surface roughness by 30% maximum, improve bearing characteristics and obtain equivalently high compressive residual stresses; however, this merit has to go with the sacrifice of belt's cutting ability.
