“…It was also reported that two flute twist drills gave less delamination and burr formations compared to three-flute and four-and eight-facet drills [13]. The use of coolants during drilling of GLARE® was found to reduce burr formations, enhance borehole surface finish, and lower the workpiece temperature [8,9]. The laminate thickness and fiber orientation of composite layers were found to influence a number of hole quality parameters and cutting forces [8,9,12,14].…”

“…The range of hole perpendicularity error can vary depending on the type of cutting process and workpiece material as depicted in Table 1. As it can be concluded from the literature, up to the knowledge of the authors, there were no studies which have previously looked into the impact of applying coolants during the machining of FMLs except in two of our previous work on drilling GLARE [8,9]. The current study aims to fill the gap in this field and complement on our previous work, by conducting an experiment to examine the impact of cutting parameters (spindle speed, feed rate), depth of cut, and fiber orientation on hole perpendicularity error in two grades of GLARE® laminates under dry, cryogenic, and minimum quantity lubrication.…”

Conventional twist drilling is a widely used machining process for creating holes in aerospace and automobile structures. Drilling at room temperature can sometime affect the quality of machined holes due to increased thermal effects on the workpiece. Thermal effects can be a cumbersome when machining composites and fiber metal laminates due to their different thermal expansion coefficients, which may introduce additional stress in the structure. Thermal machining effects can be minimized using coolants supplied either directly or indirectly to the cutting tool-workpiece interaction zone, to remove away part of the generated heat. The use of coolants adds extra costs for handling, disposal, and environmental impact. Therefore, environmentally friendly cooling technologies are replacing conventional cooling methods to reduce costs and impact on the environment. In addition, the selection of machining parameters has great influence on the hole quality. This paper investigates the impact of drilling parameters and two modern cooling technologies namely cryogenic liquid nitrogen and minimum quantity lubrication on the hole perpendicularity error of fiber metal laminates commercially known as GLARE® (Glass Laminate Aluminum Reinforced Epoxy). It was also found that applying cryogenic liquid nitrogen or minimum quantity lubrication does not lead to an improvement in hole perpendicularity error in GLARE® laminates.

“…An effective method to reduce machining temperatures is refrigeration cooling in which the liquid nitrogen is used as the coolant, usually. Various researchers by using the cryogenic method have examined the machining process in theory (Bajpai et al 2015), Rana et al (2016), Schoop et al (2016), Umbrello et al (2016)), and experiment (Biermann et al (2015), Dinesh et al (2016), Giasin et al (2016), Gupta et al (2016)). When cryogenic science is discussed, it is implied the use of refrigeration of fluids with lower temperatures than -150 .…”

Drilling process of fiber metal laminates (FML) requires a proper design of the processing parameters to prevent the occurrence of several issues and minimize defects, which can be detrimental for the integrity of the parts. These aspects become more critical in dry machining used in aeronautic field. In this scenario, the monitoring of process temperature is crucial to obtain useful information for machining optimization since many critical factors, such as matrix burnout, fiber pull‐out and delamination, depend on the heat generated during the machining. The aim of this work is to monitor the temperature measured on the tool and workpiece during dry drilling of Al/GFRP (GLARE) and Al/CFRP (CARALL) hybrid laminates. The influence of the cutting speed on the temperature trends was analyzed. Two different set‐ups were designed to measure the temperature on the tool, near the cutting edge and on the flank, and inside the laminate, in both the metallic and the composite parts. In addition, a numerical model to analyze the process temperature trend during drilling has been developed. The increasing the spindle speed from 1500 to 8000 rpm resulted in a decreasing of maximum temperatures of approximately 10°C on the tool tip and on the flank for the GLARE, and of almost 20°C in the CARALL laminates. The numerical simulation also pointed that the temperature fields is dictated by the thermal properties of carbon and glass fibers: temperature profiles within the CARALL were found smoother than those observed in GLARE.
