“…It has been observed that the thrust force tends to rise linearly with feed for any level of spindle speed for 4‐facet and step drill. The result corroborates the findings of many investigations . However, the variation in thrust force with feed is nonlinear for parabolic drill; the thrust force initially increases with feed and then starts decreasing with further increase in the level of feed.…”

The rising concern regarding global warming has ignited a quest in the research fraternity towards development of sustainable materials that can reduce the carbon footprint. Natural fiber reinforced composites have made an excellent impression in the area of sustainable development because of their environmental and ecological aspects. These materials are widely used for manufacturing of engineering products. But, the use of natural fiber composites for engineering applications necessitates making of holes in order to ascertain assembly of several components by means of mechanical fastening. In this research endeavor, the drilling behavior of nettle/polypropylene (PP) composites has been experimentally investigated. The relative significance of the input process variables has also been studied with the help of statistical technique called analysis of variance (ANOVA). The present study established few significant facts in context of drilling of natural fiber reinforced composites. It has been observed that the facts established for drilling of synthetic fiber reinforced thermoset composites cannot be directly applied for natural fiber reinforced composites. POLYM.

“…Rajmohan et al [11] have carried out experiments on Al/SiC hybrid composite materials and analyzed the thrust force which is needed for the drilling of composites with the help of 3D surface and contour plots. Kumar et al [12] have conducted experiments to study the thrust during the cutting of fiber reinforced plastics. They have used vinylester as the matrix materials.…”

Glass Fiber Reinforced Thermoplastic composites (GFRTP) are an important, alternate to the conventional engineering materials due to their good application oriented properties.Drilling is unavoidable and an important operation used in automotive and aerospace industries in the assembly stage. The reduction of thrust force is needed to minimize the delamination. The paper examines the parameters which influence the thrust force on drilling Glass fiber reinforced polypropylene (GFR/PP). The experiments are conducted using Box-Bhenken experimental design method. Empirical relation is established for determining the thrust induced in drilling of GFRTP. The factors which affect the drilling process and their interaction are analyzed and presented in detail.

“…Study on drilling of PMCs comprising synthetic fibers is explored by many researchers [16,17]. As the applications of composites based on natural fiber are growing, the literature and machining data on drilling behavior of these composites has not been investigated in depth though few studies are available as discussed here.…”

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.
