K.Parameshwaran, R. Kamalakannan, M. Prakash, R. Kalaiarasan | pp: 08-12 | Purchase PDF
Abstract: Chatter is a self-excited vibration that occurs during any machining process. Chatter vibrations were induced during boring process due to cantilever shape of boring bars. These vibrations increase the temperature of the boring tool further which ultimately increases the tool wear. In this project a suitable damping material is fixed on the boring bar, used to measure temperature for various positioning of the damper, various levels of speed, feed rate and depth of cut. The main objective of the work is to design damped tool holder for existing machine tools with low cost. The improvement of the damping capability of boring tools and suppression of chatter were attempted using different types of dampers such as Copper and Brass. These materials are having high density and so that inertia mass of the boring tool is increased to suppress the chatter of boring operations. Modal analysis of boring bar is done by using ANSYS software in this present investigation. Modal analysis is used to determine the natural frequencies and mode shapes of a structure. The natural frequencies and mode shapes are very important parameters in the design of a structure for dynamic loading conditions.

S. Raam Kumar, R. Pirai Sudan, M. Nirmal Prethum, B. Kumaragurubaran, T. Senthilkumar | pp: 18-22 | Purchase PDF
Abstract: Direct energy conversion from sunlight to electricity is obtained through solar cells. The Efficiency of solar cells is about 23.89% in the laboratory and 13.76%. More than 30% of incident light is reflected back from the surface of single crystalline Silicon (Si) solar cells because of the high refractive index of Silicon material. The initial objective of this project is to minimize the reflection losses in solar cells using an Anti-Reflection coating (ARC). In solar cell applications, a single layer thin film Anti-Reflective coating is often used. But such a Single Layer Anti-Reflective coating (SLARC) and Double layer Anti-Reflective coating reduces reflectivity only in a limited range. Triple Layer Anti-Reflective coatings (TLARC) are so widely utilized to improve conversion efficiencies and current density of silicon solar cells. Such Triple layer anti reflective coating can eliminate the need for a mechanical tracking device for proper optical alignment of the solar cell with respect to incident sunlight.
Metal Bonded Fullerenes as an Additive in Lubricants
K. Jayabadhrinath | pp: 23-25 | Purchase PDF
Abstract: The fullerene (C60) molecules having the ability to roll against the surfaces contributes to its lubricating property. The high impact strength and shear strength of fullerenes makes it a better lubricant. Metal bonded fullerenes are stable. The bond breaks upon application of pressure due to moving parts causing shear between the molecules breaking the weak metal bonds. The bond breaks making the fullerenes free to move thus reducing friction between the moving parts. As the fullerenes are electrophilic they attract any electron rich compound and again forms a weak bond which breaks upon application of force thus protecting the fullerene molecules being washed off when the machine is not in use. This increases the efficiency of the machine reducing friction also reducing the wastage of lubricant.
