“…Numerous methods have been used to measure delamination like scanning electron microscope [1], C-Scan [3] and shop microscope [5,10]. In general a measureable assessment is required in order to assess the effect of the cutting parameters and the geometry of drill tool [1][2][3][4][5][6].…”

India offered a biggest source of natural fiber like banana, rice husk, coconut and jute fiber etc. All the natural fiber has its unique advantages as well as mechanical properties which are very useful in the development of potential composites for various applications like transportation, automotive etc. There are various machining process in which drilling is most useful process for the assembly of different work pieces. During the drilling of composites it will undergo in the delamination process, which in turn reduces the strength as well as the efficiency of composites materials. In the present work drilling was carried out by using the various feeds (0.1, 0.2, 0.3 mm/rev), speeds (1000, 2000, 3000 rpm) and drill point angles (90 0 , 104 0 , 118 0) on the banana polyester reinforced composites. The delamination factor was measured by using machine vision system and digital image analysis. The mathematical model were developed using regression analysis to correlate the various machining parameters with the delamination factor and thrust force. Also the ANOVA has been used to found the effectiveness of the factors as well as their combinations. Optimization has been performed using the desirability function to find out the optimum machining condition for drilling of banana fibre reinforced composites.

The use of glass fiber polymer co mposite materials are on the rise due to their special properties like high specific strength and stiffness, excellent corrosion resistant, high damping, lo w thermal expansion high factor toughness. Majorly it is used in the fields of aerospace and automobiles especially in defense use. Though, manufacturing of these of these laminates are easy to their required shapes but obtaining a drilling in the laminate poses difficulty, due to its anisotropic non homogeneous nature. The rate of rejection at the final stage due to non selection of right machining drill parameters wh ich makes the researchers to find the optimal solution effectively. So met imes rejection rate accounts up-to 60% and hole drilling being one of the last operations creates many problems, mainly delamination stress concentration and improper hole quality with impounding higher cost factor. This paper presents an investigation on aspects of various mechanical properties and drilling of Glass fibre Mat Co mposite. Drilling experiments was conducted to study the delamination factor and hole quality on GFRP co mposites. Also the study carried out for Tensile Strength, Hardness and Flexural Strength of Glass Fibre Co mposite.

“…The author concluded that the quality of the drilled holes was improved by using a solid carbide eight-facet drill. Babu et al [3] studied the influence of drilling parameters on natural fibre-reinforced plastic with a cemented carbide drill, and the results were compared with GFRP composites. The analysis was carried out using the Taguchi technique as well as ANOVA.…”

This research work attempts to study the most prominent factor of the drilling operations performed on different thicknesses of biaxial glass fibre reinforced with graphene platelet nanopowder and epoxy composite using three different drills. Damages are induced in the workpieces to analyse the effect of changed cutting parameters and different tool materials for varied thicknesses of the plates during the drilling process. The resultant drilled hole exhibited surface irregularities that are measured using SURFCOM 1400G. The circularity deviations of the holes are measured using a coordinate measuring machine. Image-processing technique is used to calculate the area of maximum diameter of the damaged zone. Using these data, delamination at entry and exit is calculated. Utilizing response surface methodology and grey relational analysis, the varied operations are carried out and analysed with different tool materials for common cutting parameters. It is found that the lesser thickness workpiece with selected HSS drill under high speed and low feed rate is the best variable option.
