“…Previous works has been invested particularly in the drilling and milling operations in order to identify the overall variability behavior of NFRP during machining process in terms of surface roughness, cutting forces and delamination factor using statistical analysis of variance. These studies [17][18][19][20][21][22][23][24][25][26] show that the cutting feed rate has larger effect on the cutting forces, delamination factor and surface roughness, followed by the tool diameter for drilling process and depth of cut in the case of milling operation. The cutting speed has the lowest contribution on the modification of the cut surface state.…”

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.

“…The main outcome of these studies is that the feed rate has the larger contribution to the machining response [18][19][20][21][22][23][24][25][26][27]. Indeed, cutting forces, delamination factor and global surface roughness increase by feed rate increasing.…”

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.

Bajpai and Singh [19] studied the drilling performance of sisal-polypropylene composite material with process parameters, namely feed rate, cutting speed and the drill point geometry. Venkateshwaran and Perumal [20] analyzed delamination of the composite plates and by varying the feed and speed.…”

Cotton fiber composites are currently used in the interior parts of automobiles, insulation boards, fiber boards and various parts of high-friction mechanical assemblies. These composites are subjected to machining operations. Drilling is an indispensable machining operation for assembly of different parts. The present work aimed to experimental and analytical investigations on drilling of bi-directional cotton polyester composite.Influence of feed, spindle speed and drill point angle on machining characteristics like thrust force, torque and delamination factor was studied by conducting experiments derived from Taguchi's L27 orthogonal array. To determine the significance of each drilling process parameters and their interactions analysis of variance (ANOVA) test was conducted. Modeling of drilling parameters was carried out through multiple regression analysis and their optimization for minimizing cutting forces and machining induced damage was carried out using S/N ratio analysis.
