“…Multiple Layers were stacked together using hand layup in the four specimens depending on the weight of the fiber used, the weight fraction ratio of the fibers is 37%, polymer is 34% and 29% for Aluminum.. Stacking sequence was in certain order and different orientation angles as described in Table (1) and figure (3) and (4). To begin the manufacturing, first releasing agent must be applied on the glass mold to prevent the workpieces from sticking in the mold, the specimens were made by applying some of the resin on the aluminum alloy layer and then on the fiber layer till the last layer of aluminum as in figure (5), after that the specimen was placed in a glass mold and then in the oven for curing. The heating method included applying heat to the composites, then immediately specimens were placed in the oven at 52°C for 5 hrs.…”

“…For this composite specimens the optimum parameters for the best surface roughness are A3B3C3 (A3=5000r.p.m, B3=1600mm/min, C3=2mm) that is illustrated in figure (10). The nine experiments that had been applied to the composite and the measured surface roughness, four values for each experiment, are all listed in table (4) and the input parameters with their results of Ra are illustrated in table (5). The experiments work well in the final square shape, but there are fiber burr in most of the experiments, also separation occurs only in Exp.…”

In this paper the ability of fabricating laminate composites by manual layup was discussed. Heating method was used to manufacture the composites; heat was applied to approximately 12 hours with specific heat temperature. There were four types of laminate composites fabricated and studied in this research, containing Aluminum alloy 6061 as the common element in all types, two types of fibers; woven Carbon fiber with two different orientations: ±45°, ±60°, random fiberglass and with two types of resin; epoxy resin and polyester resin. Different types of composites were made to determine the effect of CNC milling machine to the measured surface roughness and for specified parameters. The weight fraction ratio of the fibers is 37%, polymer is 34% and 29% for Aluminum. The parameters selected are spindle speed, feed rate and depth of cut. The L9 Taguchi orthogonal arrays, signal to noise (S/N) ratio and analysis of variance (ANOVA) are selected to determine the effect of these parameters; it was analyzed by MINITAB 17 program. The results showed that the parameter were significant more to the epoxy resin specimens than polyester resin specimens. The optimal milling parameters for good surface finish for Aluminum – Carbon fiber composite are at 3000RPM, 1200mm/min, 1.2mm, and for Aluminum – Fiberglass composite are 5000RPM, 1800 mm/min, 2.0mm.

“…The surface roughness is better at high spindle speed, low feed rate, and low depth of cut. Feed rate has the most dominant factor in influencing the surface roughness 𝑅𝑎, followed by spindle speed [10]. The use of Taguchi enhancement system was explained by [11] in advancing the cutting parameters of milling processing for machining the halloysite nanotubes (HNTs) with aluminum fortified epoxy hybrid composites through the dry condition.…”

 Fibers, metal and resin were made up together using mold and compression method.  Hand layup was used and Taguchi method for obtaining the optimum parameter.  The workpiece with most significant parameters is FG-Al with polyester resin.  The best Ra after milling is for FG-Al, CF-Al with polyester resin.Recently, composite materials were widely used in different applications due to their lightweight, and good thermal and mechanical properties. In this study, an attempt to manufacture laminate composites by hand layup was performed. Also, optimal parameters for the best surface roughness were investigated. Therefore, three parameters had been examined; spindle speed, feed rate, and depth of cut. The L9 Taguchi orthogonal array, signal to noise (S/N) ratio, and analysis of variance (ANOVA) were selected to determine the optimum parameters. To create composites, the compression method was employed. Four different types of composites were manufactured with 2.8 mm thickness, to determine the effect of the parameters on the surface roughness and for specified parameters using the CNC milling machine. The weight fraction ratio of fibers was 39%, the polymer was 34%, and 27% for Aluminum. The results showed that the optimum parameters for surface roughness in milling machine of composites for Polyester resin for aluminum-fiberglass composite are; spindle speed=5000 r.p.m, feed rate=1600 mm/min, depth of cut=1.6 mm and Ra=1.853 μm, and for epoxy resin; aluminum-carbon fiber composite is spindle speed=4000 r.p.m, feed rate=800 mm/min, depth of cut=1.2 mm and Ra=2.43 μm.

In this research work an attempt has been made to try to investigate the effects of cutting parameters such as feed rate cutting speed and depth of cut on surface roughness in turning operation of 16MnCr5 steel, is a case hardening steel with by the support of Taguchi technique. An orthogonal array, signal to noise (S/N) ratio and analysis of variance (ANOVA) were used to determine the effects and contributions of cutting speed, feed rate and depth of cut on the response variable. Turning operations were carried out by Tungsten carbide coated cutting tool inserts. The experiments were conducted at three different cutting speeds (400, 600 and 800 rpm) with three different feed rates (0.06, 0.12 and 0.18 mm/rev) and a constant depth of cut (0.5, 1.0 and 1.5 mm). The cutting parameters are optimized using signal to noise ratio and the analysis of variance.obtained result data revelled that depth of cut has most significant effect over surface roughness followed by cutting speed while feed rate has lowest effect.
