 Abstract

In this project, Taguchi method was employed to optimize the copper powder concentration in dielectric ?uid for the machining of hastealloyusing Electrical Discharge Machining (EDM). The process parameters such as discharge current (A), powder concentration and pulse on pulse off (Ton&Toff) were changed to explore their effects on Material Removal Rate (MRR). It was observed from the experimental results that the copper powder added dielectric ?uid signi?cantly improved the MRR. Analysis of Variance (ANOVA) and F-test of experimental data values related to the important process parameters of EDM revealed that discharge current and copper powder concentration has more percentage of contribution on the MRR.The main aim of our project is to investigate the effects of nano-fluid in electro discharge machining of hastealloyusingtaguchiapproach.

 Abstract

The absorption of heavy metal from dying industry wastewater by charcoal from various ecofriendly natural available absorbent materials. The discharges of industrial effluents into aquatic environment cause a potential threat to the aquatic life as well as human health, which is a matter of great concern due to their toxic nature and adverse effect. The small scale dying industries generate a large amount of pollution load which in many cases is discharged into environment without any pre-treatment. The dying industries release harmful heavy metals which is 3 to 4 times higher than standard values. Heavy metals as been considered as one of the most toxic pollutants due to its carcinogenic and teratogenic nature. Several methods have been adopted for the removal of heavy metals from dying industry wastewater. These include chemical reduction, precipitation, ion exchange, electrolysis etc., but these process will contain more expensive so the small scale industries will not used those process for removal of heavy metals. In the present study, peel of jack fruit , bamboo charcoal, bark of mango are used. After activating materials are used as absorbents, the peel, charcoal, and bark are used for chromium, cadmium and lead removal process. The effect of various parameters such as dosage of absorbents for the removal of heavy metals, pH and effect of contact time, are studied. The absorbent gives the optimum results. The natural material gives 99% heavy metal removals.

 Abstract

In automobile the suspension system is essential to absorb shocks, vibration and bumps etc. Vehicle is run on different type road conditions such as even, uneven, rough etc. The automobile frame and body are mounted on front and rear axle through springs and shock absorbers. This is essential to damp out road shocks transmitted to the frame by the wheels when they roll over uneven road. This creates discomfort to the passengers and produces stresses in the frame and other parts of the automobile. The passenger experiences the jolts by the forward movement of the vehicle and jerks due to uneven road conditions. Even under good road condition the passenger are also subjected to bounce and roll when cornering and pitch when the front wheels are suddenly lifted or dropped in relation to rear wheels that means suspension system work continuously. Due to varying conditions of heating, ventilating, cooling and dehumidification in the atmosphere at various places, the air conditioning of automobiles is very essential. To maintain human comfort and improve internal atmosphere in an enclosed space, proper control of freshness, temperature, humidity and cleanliness of the air is required. So, in this project we are using renewable energy of suspension system to produce air conditioning effect in automobile.

 Abstract

The experiment is carried out to assess the strength and workability of concrete using M sand. We add the admixture of SIKA to increase the strength at very short days of curing. As decreasing the days of curing that result in increases the time management in construction. The specimens were allowed for curing and determine the compressive strength, flexural strength and split tensile strength.

 Abstract

:This project takes us through a journey that deals with the control of distortion during welding of boiler panel assembly. During the study of this project we found that the distortion control was a major problem. The combined handwork put by us together has revealed that there is a solution to control the distortion during welding of boiler panel assembly. The data collected tells us that the distortion can be controlled by improved technique. The suggestion put forth by us in control of distortion during welding of boiler panel assembly has the project to new dimension and the final outcome for this project is productive for us and also to company.

 Abstract

Simplification of engineering and precise control of manufacturing process can result in significant cost saving. The most cost effective way, which can pay big dividends in the long run, is flexible manufacturing. Manufacturing need not be high ended and to be sophisticated.By employing DFMA (design for manufacturing and assembly) technology we achieve most attractive results. It required conscious effort to identify areas where this technology can be implemented. Circular saw machines and grinding machines are used in wood working industry on a large scale in many countries. The scope based on the existing wood cutting machine and the appropriate of DFMA methodology. The machine designed and manufactured can perform multiple operations at the same time on wood with required speed and controlled or operated by motor. It can perform cutting, grinding and buffing operations. In this paper, the preliminary design, valuation of design requirements and the design results are described. We are sure that the information contained in this paper would certainly prove useful for better insight in the scope and dimension of this project in its true perspective.

 Abstract

:India is an agricultural country cultivating ground nuts quantity in the village sides of the country. Groundnut is a crop of global importance. It is widely grown in the tropics and subtropics, being important to both smallforming and large commercial producers. Groundnut business is a huge market and faces huge profits when they are planted and maintained perfectly. The available planting machines are imported from foreign countries. The imported machines are not only bulk in size but also costing around lakhs. Also planting groundnuts manually consumes lot of time which can be saved by automating the process.In this project an attempt has been made to the design and fabrication of multi agro machine exclusively for small farmers at low cost. The machine is made versatile such that very simple components are employed in the fabrication and this is the reason for the low cost of the machine. The main objective of our project is to carry out the groundnut threshing operation, seed sowing, and fertile spraying simultaneously. The modelled components are fabricated and assembled together to form a complete machine.

 Abstract

This paper describes the working of a cycle which works on pneumatic power. A pneumatic cycle uses compressed air as a source of energy for locomotion. In this system a single acting pneumatic cylinder is operated as a slider crank mechanism which converts the linear reciprocation of the cylinder piston rod into oscillatory motion of the driver crank about the pinion shaft.. These stated problems in this paper are overcome by a pneumatically operated cycle which has low weight, takes less time for refueling and requires less maintenance. The Hybrid Bicycle can either be pedaled manually or be run on compressed air. Compressed air is used to turn the real wheel through a slider crank mechanism via a chain and sprocket. The actuation of the pneumatic piston used in the slider crank mechanism is controlled by a 5/2 pneumatic directional control valve which in turn is actuated by a push button through cam and follower arrangement connected to the crankshaft. This ensures that the pneumatic piston expands for half the revolution and contracts for the other half. A push button valve actuates this mechanism and a flow control valve is used for speed control.
