“…Giasin et al investigated the surface roughness and burr formation in drilling of fiber metal laminate (GLARE) by using tungsten carbide as cutting tool with three different types of coatings (TiAlN, AlTiN and TiN). Titanium nitride (TiN) coated drills displayed best results with minimum surface roughness and burr formation, whereas TiAlN coated drills exhibited maximum surface roughness and burr formation at higher spindle speed [23]. According to Ozkan et al during milling of CFRP's with TiAlN and TiN coated carbide tools, maximum surface roughness was observed at lower cutting speed and feed rate in TiN coated carbide tool.…”

The carbon fiber reinforced polymer composite has made a substantial impact on the manufacturing sectors owing to its excellent mechanical, thermal and corrosion resisting properties. The surface roughness mainly depends on the machining parameters while drilling of carbon fiber reinforced polymer composite laminates. The study concentrates on the impact of uncoated and titanium nitride coated solid carbide drills on minimizing the roughness that is generated while making holes in bi-directional carbon fiber reinforced polymer composite by optimizing the drilling constraints [spindle speed (A), feed rate (B), point angle (C) and drill diameter (D)]. Experimental studies are carried out using Taguchi L 27 orthogonal array. The investigation discloses that the drill diameter is one of the most influencing cutting parameters followed by spindle speed and feed rate. The response surface methodology is chosen as a tool for predicting and optimizing the process parameters. The investigation also discloses that the experimental and the predicted results of surface roughness are closely matching with each other. The surface morphology illustrates that titanium nitride coated solid carbide drills minimize the surface roughness compare to that of uncoated solid carbide drills.

“…The circularity error at the hole entry was defined as the difference between the maximum radius (D min ) of a circle that can be circumscribed outside the circular hole profile and the maximum radius (D 0 ) of a circle that can be inscribed and completely enclose the circular hole profile without cutting it and is concentric with the maximum circumscribed circle [7], as shown in figure 4.…”

“…Hole quality is generally estimated based on a number of parameters, such as surface roughness, circularity error [2][3][4][5], which in turn are affected by the machining parameters, including drill geometry. Thus, many studies have been conducted for the last several decades to characterize the influence of cutting parameters on the hole surface quality and to understand the tool wear mechanisms in the drilling of polymers and polymer based composites [6][7][8][9][10][11][12][13][14]. Delamination is another major problem associated with machining of fiber-reinforced composites, which tends to reduce structural integrity of the composite structures [3][4].…”

“…Regardless of the material type, unfilled polymers, glass fiber reinforced polymers or carbon fiber reinforced polymers, several modern technologies, such as digital microscop and ultrasonic C-scan techniques [17], light optical microscopy [16], scanning electron microscopy [7] or X-ray photoelectron spectroscopy (XPS) [9], non-* email: nicusor.baroiu@ugal.ro distructive methods [16] were also considered in the attempt to study the influence of parameters on the quality of the machined surfaces in dry drilling, leading to an improvement of machining process quality. In order to asses the effect of various process parameters on the machinability of polymers and polymer-based composites (thrust force, torque, surface finish, circularity of the hole, delamination factor etc.…”

Drilling of polymeric materials can be challenging when holes are produced in large scale due to the necessity of controlling the holes quality. This paper presents the effect of machining parameters on the hole quality, in terms of surface roughness and circularity error, in drilling of high density polyethylene, polyamide and polyacetale. The analysis of variance was performed in order to assess the significance of cutting parameter on the hole quality parameters. The experimental results indicate that different cutting conditions are to be employed in order to achieve the optimum surface roughness and circularity.

“…Işık [22] examined the effects of cutting parameters such as depth of cut, feed rate, cutting speed, and tool geometry on surface roughness in machining of GFRP composites. The cutting force and power consumption could be controlled with cutting parameters and tool materials [23][24][25]. Surface roughness also varies depending on cutting parameters and tool material.…”

Glass fiber-reinforced plastic (GFRP) composites take place in engineering materials owing to their low-weight and high-mechanical properties. In some cases, they need to be shaped by machining before using in industrial applications. However, when these composites are machined, many problems such as bad surface quality, rapid tool wear are encountered. Therefore, optimization of cutting parameters is essential to eliminate or minimize these problems. In this study, GFRP composites were produced by combining polyester matrix material with glass fibers (GF) having 6 mm, 6-12 mm, 12 mm fiber length, and 20%, 25%, 30% fiber ratio by weight. The tensile strengths of these composites were investigated. Turning tests were also performed with cutting speeds of 40, 80, and 120 m/min, feed rates of 0.1, 0.2 and 0.3 mm/rev, and depth of cut of 1, 2, and 3 mm, according to Taguchi L 27 standard orthogonal array method. The effect of fiber length and ratio, and cutting parameters on cutting forces and surface roughness were analyzed. As a result of the experiments, it was observed that the reinforced polymer matrix with GF provide to increase the tensile strength. The highest tensile strength was obtained as 55.95 MPa from the composite having a fiber length of 12 mm and a fiber ratio of 25%. Besides, the feed rate was determined as the most effective parameter among the all parameters on both cutting force and surface roughness. Therefore, the feed rate should be chosen low for lower cutting force and surface roughness values.
