“…Consequently, grey relational analysis (GRA) can lead to the simultaneous optimization of all parameters, which jointly contribute to a general characteristic that expresses the effectiveness of drilling, i.e., the material removal rate (MRR). For example, this has been applied to two epoxy composites reinforced with natural fibers: jute/flax hybrids [24] and sisal basket weave fibers [25]. A notch is created when the spinning drill bit penetrates the substrate of the material, which is generally detrimental to the laminate's properties [26].…”

This review highlights the influence of parameters on the drilling characteristics of biocomposites including natural fibers. The particular structure of natural fibers, including their hierarchized geometry, which potentially causes fibrillation, can result in an increased chance of irregularity of the hole and a more complex mode of delamination or, in general terms, damage to the composite. On the other hand, to attain an effective junction of the laminates in a structure, a nut–bolt procedure must be selected, which requires the performance of a drilling operation. This is becoming increasingly important since the fields of application for natural fibers and their variety have been steadily growing in the last few decades. Additionally, adequately performed drilling operations can address considerations related to circular economy. The drilling characteristics evaluated herein include thrust force, torque, surface roughness, and the delamination factor at the entry and exit of the drilling tool. The variation in tensile strength, stiffness, and strain propagation due to the presence of open holes of various sizes, the number of holes, the holes’ patterns, the effect of the type of fiber of the notches, the fiber architecture, and the fibers’ stacking sequence in biocomposites have also been discussed.

“…A fibre is considered by its length presence some better compared to its dimensions. Jute fibers are fully bio-degradable, recyclable and environmentally friendly [4][5][6]. Hybrid is the flexible system with unique properties in which combined two or more fibers types to design composite materials that overcome the drawbacks of individual fibers composites [7][8].…”

“…Currently, hybridizing natural fibers with synthetic fibers, getting innovative consideration, to prepare a composite with improved properties, such as low cost, light weight, ease of fixing. Among several types of natural fibres, jute fibre has a high content of cellulose which considers an attractive option for the special engineering materials such as construction structures, building, automotive, aerospace, biomedical materials, in an eco-friendly manner [3][4][5][6][7][8][9][10][11][12]. In last decade, natural fiber reinforced epoxy resin composites have attracted growing research benefits owing to their potential as a substitute for composites reinforced with synthetic fibers like basalt, glass, Kevlar or carbon [13][14][15][16][17][18][19][20].…”

“…Due to its high mechanical properties" jute fibers are considered as a substantial and alternative to glass and carbon fibers [13][14][15][16]. The total dimensions and its compositional reliability are substantial in better value of the fiber and the sum of these parameters is serving of the fiber finding a new investigation on drilling of GFRPs in which L orthogonal array was used for determining delamination as well as surface roughness [6][7][8][9]. The process parameters are spindle speed, feed rate and tool point angle were combined to identify the optimal process parameters.…”

Natural fabric Reinforced polymer (NFRP) composites are the materials by a matrix and a reinforcement of natural fibre. NFRPs are the materials with low density, high molding flexibility, environmentally friendly and have wide range of applications extending from products of commodity to aerospace, defence, automobile spare parts, and bicycle frames applications. In this work the effect of cutting parameters in drilling Natural fabric reinforced composites were studied. Experiments were conducted to study the effect of drill bit diameter, spindle speed and feed rate on Material Removal Rate (MRR), Surface Roughness, Circularity of Hole and Delamination Factor. Theoretical calculations are done to calculate Material Removal Rate and Delamination Factor. Surface Roughness and Circularity of Hole measured by Surface Roughness Tester and Coordinate Measuring Machine (CMM) respectively. The input parameters considered were 6mm, 8mm and 10mm diameter drill bits, spindle speeds of 600rpm, 1200rpm & 1800rpm, feed rates of 0.1rev/min, 0.2rev/min and 0.3rev/min. Experiments were carried as per Taguchi Experimental Design (L9 ) to get the optimum values of MRR, Surface Roughness, And Circularity Of Hole and Delamination Factor. Optimization was done using Taguchi Analysis, Grey Taguchi Analysis and Multi Attribute Decision Making (MADM) Method. The optimal solution for the multiple response system of drilling of NFRP were diameter of drill bit of 10 mm, Spindle speed 600 rpm and at 0.3 mm/rev feed rate. MADM process concluded that, Circularity of Hole was most preferred response than followed by Material Removal Rate, Surface Roughness and Delamination Factor

“…The results revealed that the depth of cut has significant role to play in producing higher material removal rate and cutting speed has significant role to play for producing lower surface roughness. In the investigation analysis of jute-flax hybrid composite for surface roughness and material removal rate using optimized process parameters, [8] employed analysis of variance to find the significance of individual parameters. The results revealed that spindle speed and drill bit diameter have most effect on material removal rate and surface roughness followed by feed rate.…”

The use of optimal parameter values in an experimental investigation for minimizing surface roughness has always been the design trend of many machining operation without checking the variation levels of the process parameters if it has any measure of significant difference or not in minimizing surface roughness of the workpiece. The study carried out a comparative analysis between low, intermediate and high level of cutting speed, feed, depth of cut and tool on mild steel, stainless steel and brass using one-way ANOVA approach with the aid of statistical package for social sciences (SPSS), version 17 based on drilling operation. The findings revealed that there were no statistically significant differences between the levels for the respective workpiece in minimizing surface roughness. The result implies that the low, intermediate and high level plays equal contributing effect in minimizing surface roughness in drilling mild steel, stainless steel and brass. The study concludes that preference should not only be given to a particular level in an experimental investigation because minimum surface roughness can be achieved at any level which we might least expected.
