      Authors: Mohit Pandey, B. Doloi, B. Bhattacharyya
      Pages: 3 - 22
      Abstract: Laser marking is one of the operations performed by laser with an aim to identify products, components, etc., so that they can be easily traced with information. The multi diode pumped fibre laser with ytterbium doped as a lasing medium, was used to mark a circular shaped image. The paper aimed to study the influence of process parameters such as laser power, pulse frequency, scanning speed, duty cycle and transverse feed on responses such as mark intensity, circularity and surface roughness value (Ra, μm). The range of process parameters involved were transverse feed of 4-14 μm per laser stroke, laser power of 7.5-17.5 W, pulse frequency of 50-60 kHz, duty cycle of 20-40% and scanning speed of 5-25 mm/s. Experimental work was carried out without the supply of assist gas pressure and laser marking process was done by scanning the fibre laser for single pass. Experimental results revealed that for better value of mark intensity, circularity and surface roughness value (Ra) of circular shaped marked image, the process parameters such as laser power of 12.5 watt (W), pulse frequency of 50 kHz, duty cycle of 30% and scanning speed of 5 mm/s should be selected.

      Abstract: Advanced polymer textile composites are characterised with high strength to weight ratio and tailored mechanical properties claiming their applications in advanced engineering sectors. The research work presented is focused on the development and characterisation of compressive behaviour of monolithic Kevlar and carbon-Kevlar hybrid fabric reinforced polymer composites (FRPCs). Vacuum-assisted resin transfer moulding process is used to cast the composite laminates. Results obtained present the effect of hybridisation of carbon yarns with Kevlar fabric, also compare the compression modulus and compressive strength of two fabrics along longitudinal axes. Fabrics with different weaving patterns, namely plain and twill are considered for reinforcement to experimentally investigate the role of weaving pattern plays in governing the mechanical strength of textile composite. FE model is generated to numerically simulate the compression loading behaviour of composites. Simulation results of longitudinal compression of carbon-Kevlar hybrid fabric composite show a good agreement with experimental results.

      Abstract: This paper targeted the design and stress comparison of a small-scale wind turbine blade which was constructed for the specific environmental conditions of the small rural village in Ethiopia. Firstly, the blade was designed from the characteristic of aerodynamic performance. Secondly, modelling and stress analysis of the windmills was conducted which is very significant for the further design and application of wind turbines. The material was epoxy-GFRP composite. The orthotropic mechanical properties of woven fibre epoxy polymer composite were created (ASTM D1683) with help of Autodesk Helius Composite V.16 software. The tensile and flexural testing specimens were fabricated by D3039M-17 and D7264M-15, respectively. Load, displacement, and modulus were investigated using UTM. Based on the parameters of the airfoil, the three-dimension and the assembly models of blades were mounted with the SOLIDWORK-V.16. Then the models were imported into ANSYS-V.15 WORKBENCH software for analysis. The displacement, Von Misses, and principal stress effects were determined.

      Abstract: Machining of low machinable non conducting engineering materials like borosilicate glass has imposed challenges in the manufacturing of micro devices like microfluidics, MEMS etc. Electrochemical discharge machining (ECDM), a hybrid processes of electric discharge machining (EDM) and electro chemical machining (ECM), emerging as a potential method to address the low machinability problems. In the present work the influence of helical tungsten carbide tools of varying diameter assisted with high speed tool rotation was adopted to improve machining performance in terms of on the material removal rate (MRR), heat affected zone (HAZ), radial over cut (ROC), tool wear rate (TWR) and depth of machining (DOM). It was found that the hydrodynamic region was more predominant with tool diameters 600 μm, 700 μm and at 2,500 rpm and resulted to a low machining depth. Smaller diameter tools assisted with rotational was found significant influence on the machining responses.

  • Synthesis and characterisation of nanoparticles by pulse laser ablation at

      Abstract: In recent years, material ablation at solid-solid interface by laser micromachining technique is emerging as a novel method for synthesising nanoparticles. It generates chemically pure fine crystalline particles compared to traditional methods. Moreover, it enables higher confinement of plume, thereby favouring nanoparticle growth compared to liquid-solid interface and gas-solid interface. This paper demonstrates the novel method of synthesising crystalline nanoparticles of titanium dioxide (TiO<SUB align="right">2), zinc oxide (ZnO), and graphite by laser ablation at solid-solid interface. The interface was maintained by preparing transparent ice on the target placed in a glass vessel. The size of synthesised nanoparticles is in the range of 1.5 nm to 5 nm for TiO<SUB align="right">2, 100 nm to 500 nm for graphite, and 2-10 μm for ZnO (agglomerated). From the observations, it can be inferred that the process employed gives an improved rate of synthesising crystalline nanoparticles.

  • Effect of straight and circular tool paths in micro channel fabrication
           using micro-milling

      Authors: Alwin Varghese, Suhas S. Joshi
      Pages: 87 - 103
      Abstract: Micro-milling can generate micro molds involving complex shapes rapidly as compared to other micro machining techniques. Researchers thoroughly investigated different aspects of micro-milling with straight tool paths. This paper investigates the effect of tool paths on cutting forces, tool wear and top burrs generated in micro-milling using straight and circular tool paths for micro channel fabrication. Micro-milling experiments were carried out to understand the effect of tool paths at two levels of cutting parameter values. It was observed that the tool wear rate in micro-milling along a circular tool path is more compared to that of straight tool path. Consequently, the cutting forces, top burrs and surface roughness were found to be more in circular tool paths. The flank wear rate in micro-milling along the circular tool path was estimated to be 70.9 <i>μ</i>m/m and 84.1 <i>μ</i>m/m for lower and higher levels of cutting parameters, respectively. However, the flank wear rate along the straight tool path was 57.24 <i>μ</i>m/m and 62.8 <i>μ</i>m/m for lower and higher levels of cutting parameters, respectively.

      Authors: Bhavana Mathur, Prashant Kumar

      Abstract: The present study focused on the mechanical properties of stir cast Al 6063/Al<SUB align="right">2O<SUB align="right">3 (alumina) reinforced metal matrix composites. Aluminum-alumina composites are used in various industries including fabrication, aerospace, automobile sectors, etc. The properties like corrosion resistance, low density, and high modulus of elasticity, higher thermal, and electrical conductivity make them the best choice for its applications in various industries (Prasad, 2004). The present work focus on the hardness of Al 6063/Al<SUB align="right">2O<SUB align="right">3 (alumina) reinforced metal matrix composites by varying the percentage of the reinforced element alumina in the base matrix alloy Al 6063, stirring speed and stirring time (Kok, 2005). The thickness of the sample was taken 10 mm, width 30 mm and length 100 mm. Nine samples were prepared by varying the percentage of alumina 2%, 4%, 6% (wt %), stirring speed of 800, 1000 and 1200 (Rpm) and stirring time of 5, 10, 15 (minutes). In this experiment work various works has been reviewed in which lower concentration of alumina was taken to analyse the effect on the response factor, that's why lower even concentration of alumina was taken. It was shown from the experiment that the hardness value increases with the increase in reinforcement percentage but after that, there was a decrease in hardness value.
