Composites are widely used in all the fields because of its favorable properties over conventional materials. Medium Density Fiberboard (MDF) is an extensively used wood composite in furniture industries. Drilling is the most commonly used machining process in the assembly. The surface quality of the hole depends upon the cutting conditions. The drilling damages like delamination reduces the structural reliability of the laminates and also affects the assembly of parts, appearance and the performance of the final product. The objective of this study is to analyze the influence of cutting parameters in a systematic approach on delamination in drilling of prelaminated MDF wood panels with High Speed Steel (HSS) twist drills of different diameters. The drilling experiments were planned and performed using Taguchi design. Response Surface Methodology (RSM) based mathematical model is developed to predict the influence of process parameters. The adequacy of the model is checked using Analysis of Variance (ANOVA). The results showed that the most dominant factor which influences the delamination is feed rate followed by the drill diameter.Keywords

In this work an attempt has been made to develop empirical relationships to model thrust force in drilling of GFRP composites by Multifaceted drill bit. The empirical relationships were developed by response surface methodology incorporating above drilling parameters. The developed model can be effectively used to predict the thrust force in drilling of GFRP composites within the factors and their limits are studied.Keywords

Carbon Fibre Reinforced Carbon (CFRC) Composite material is highly used in advanced industrial sector, especially in manufacturing of space shuttles and other expensive aerospace categories. The material's significant position and its growing importance has created interest among research community about the machining technology of this special material. This paper aims at finding the experimental drilling characteristics values of C-C composite by the combination of Taguchi method and Grey theory Technique. Manufacturing of good quality products at lower cost is the main objective of the modern industrial sector, and this is obtained by using optimal methods to the manufacturing conditions. This paper discusses about the use of Grey Theory to find the optimum drilling values. The experiments were conducted by using a Titanium Nitride coated Carbide drill tool on a carbon-carbon composite material plate with CNC Drilling Machine. This paper explains and demonstrates the influence of optimal set of characteristics, such as Spindle speed, Feed and Tool angle on the Delamination factors.Keywords

Objectives: To study the effect of modified (OMMT) nanoclay polyester resin on dynamic properties of Glass Fiber Reinforced (GFR)- Polystyrene Foam (PS) sandwich laminates experimentally. Methods/Analysis: The GFR– PS foam sandwich laminates are fabricated by hand lay-up process. Free vibration test has been conducted to evaluate dynamic properties of glass laminate and sandwich laminates. The morphological picture of the nanoclay dispersion in the polymer fracture samples has been investigated by using Scanning Electron Microscopy (SEM). Findings: The dynamic properties of the nano polyester sandwich have been significantly improved at 4% of nanoclay loading. Application/Improvement: From the results it is observed that, the effect of nano particle in fabricated composite significantly increases the dynamic properties.Keywords
