The present study is focused on liquid nitrogen treatment of M2 tool steel for 12 hours, 24 hours, and 36 hours at-196 0 C followed by tempering at 150 0 C. The treated tool samples are used for machining low carbon steel on a CNC lathe to varying combinations of Spindle speed (700, 1100 & 1800 rpm), Feed rate (0.1, 0.125 & 0.15 rev/mm) and Depth of cut (0.15, 0.3 & 0.45 mm). Taguchi's Design of experiments and ANOVA methods are used to statistically analyze the effect of cutting parameters and cutting forces on the tool wear and surface roughness after experimentation. SEM analysis is carried out to investigate the type of tool wear experienced by the cutting tools. The regression analysis has resulted in a model to predict the values of surface roughness, tool wear and friction coefficient, with a maximum error of ±6% from the actual experimental values.

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.

“…Among the drilling variable, feed rate and cutting speed are dug up to have a considerable influence on thrust force and thus delamination in drilling operation. [22][23][24] Researchers reported that increased feed rate leads to occurring larger damage around drilled hole. 1 According to some researchers, cutting speed also plays an important role in forming delamination; while, others reported that its effects on delamination is limited.…”

The reinforcements of nanoparticles have an important role in improving the machinability of nanocomposite materials. Except for the known nanoparticles such as carbon nanotube, graphene, nanoclay, etc., the effect of boron nitride reinforcement on the machinability of composite materials are a recent research topic. In this study, boron nitride nanoparticle was introduced to the matrix resin that brings about additional strength and enhancement in thermal and mechanical properties of the composite. Though it was confirmed that this composition enhances the focused properties, it is necessary to investigate drilling performance of these composite and identify the effects of this boron nitride nanoparticle on machinability of carbon fiber epoxy nanocomposite considering thrust force, delamination factor, etc. Accordingly, while the thrust force is increased by reinforcement of the boron nitride nanoparticles, on the contrary of literature, delamination factor is tend to reduce as compared with reference composite. This experimental study shows the addition of boron nitride nanoparticles help to reduce delamination factor of carbon fiber epoxy nanocomposite. In addition, hole surfaces and drilling mechanism analyzed with optical and scanning electron microscope about damage estimation.
