“…Higher helix angle decreases the temperature at the tool, which can be observed by Table 4. Increase in feed rate increased the surface roughness and cutting force similar to others researches [23,24]. Enhance in feed rate decreased the temperature slightly during drilling of AMMC under the lubricated condition.…”

The aim of the current work is to optimize the drilling constraints simultaneously during drilling of an Al6063/TiC composite based on grey relational analysis. Drilling trials were performed on Al-6063 reinforced with 15 wt% titanium carbide (TiC) of size 50 μm. HSS twist drills with diameter of 10 mm under lubricated condition were utilized for performing drilling tests. Drilling parameters explicitly helix angle, spindle speed, feed rate and responses such as surface roughness, cutting force and temperature are considered in the study. Grey relational grades were calculated to find the optimum levels of parameters, and moreover major involvement of constraints was dogged by ANOVA. The drilled composite specimen surface was analyzed under scanning electron microscopy (SEM). SEM metaphors of the drilled composite face specified the charisma of grooves, micro-cracks and dents.

“…6a, was drilled through the CFRP layer. The drilling was done with the steel side up as the drilling direction might affect the interface otherwise [29]. In reference to this hole, the second center hole of each specimen was machined on its defined position using a vertical NCmachining center VF-3 of the company Haas (Oxnard, USA).…”

This work shows a new way of single lap shear specimen production for hybrid metal-composite materials, which can be used to characterize process-induced interface property variations. Due to this special procedure, the specimen manufacturing can be done production-related and with a homogenization of the thermal stresses occurring in the joint area of the hybrid at each specimen. The exemption process of the specimen is kept in a minimum invasive way, not affecting the interface in the tested zone. The influence of the metal surface structure specifically created by micro form milling as well as the influence of the curing temperature on the maximum shear strength of the interface, were investigated. Finally, the driving failure mechanisms were identified and described.

“…Optimum parameters determined are 0.1% Nano content, 530rpm spindle speed, 0.04mm/rev feed rate and 5mm drill diameter. Dhiraj Kumar et.al [6] has studied the delamination effect in GFRP with the use of three dissimilar tools with different geometries and materials. Laminates were prepared with vacuum bagging method.…”

Drilling can be defined as a metal removal process in which holes of required size & depth from minimum to maximum can be obtained with the help of a rotary cutting tool called the drill bit. The requirement of micro holes in various applications such as filters in the medical field and circuit boards have resulted in the development of Micro Drilling operation as they reduce the production time and cost. In this paper, the literature survey on various challenges in the micro drilling of GFRP such as tool wear, drilling parameters (speed, depth of cut and feed), de-lamination, use of coated and uncoated tools, tool materials and their micro structural characterization has been performed. From the past few years, it can be concluded that there is a very small work that has been done in the area of micro drilling of GFRP. Today there is a need for the development of various advanced techniques to fulfill the need at a better cost and reduced time.
