The process of investment casting also known as “lost wax casting”, is one of casting methods to fabricate metal part with a complex shape. Flow behavior of stainless steel grade 304 at the temperature higher than 1550°C is a critical factor in casting mould design of the lost wax process. Non-desired heat transfer phenomena and using of the unsuitable mold design normally lead to defects in casting such as misrun, cold shut, shrinkage, pin hole and porosity. Parameters in casting such as pouring temperature, preheating temperature, pouring time, pouring rate and cooling rate were given by the current production condition.

Major barrier for the aluminum welding is the surface oxide layer which induces higher resistance for the welding of resistance spot welding. It results in the immediate tip wear of electrode and also gives effect on the properties of weld material in the resistance spot welding. Studies show that the significant cleaning of oxide layer upto few microns can enhance the electrode force and also low current and high frequency can significantly reduce the contact resistance which finally increases the joint quality of the aluminum. Interlayer of stainless steel can also change the fusion properties of the aluminum. Other interlayers like Al-Mg, Al-Cu28 also increase the formation of intermetallic compounds and improve joint quality.</em></span></span></p><p class="MsoNormal" style="text-align: justify; text-justify: inter-ideograph;"><span style="font-family: "Times New Roman", serif;"><span style="font-size: 16px;"><em>Cite this Article</em></span></span></p><p class="MsoNormal" style="text-align: justify; text-justify: inter-ideograph;"> </p><p class="MsoNormal" style="text-align: justify; text-justify: inter-ideograph;"><span style="font-family: "Times New Roman", serif;"><span style="font-size: 16px;"><em>Arick Lakhani, Darji PH.

The composites were prepared by semi solid stir casting process. Tensile specimens with ASTM B557 standard dimensions were prepared from the composites. These specimens were subjected to uni-axial tension under the 10 t capacity UTM. The specimen’s FEA models were created using ANSYS 16 and the stress strain values were obtained. The actual results were compared with the predicted values obtained from the FEA. It was ensured that the FEA results had well agreement with the original deformation length with in the acceptable error margin.</span></span></p><p class="MsoNormal" style="text-align: justify; line-height: normal;"><span style="font-family: "Times New Roman", serif;"><span style="font-size: 16px;">Cite this Article</span></span></p><p class="MsoNormal" style="text-align: justify; line-height: normal;"><span style="font-family: "Times New Roman", serif;"><span style="font-size: 16px;">Tarasasanka C, Ravindra K.

R. Sanghaniscr1385@yahoo.comG. D. Acharyascr1385@yahoo.comK. D. Kothariscr1385@yahoo.com<p class="MsoNormal" style="margin-top: 6.0pt; margin-right: 0in; margin-bottom: .0001pt; margin-left: 0in; text-align: justify; text-justify: inter-ideograph;"><span style="font-family: "Times New Roman", serif;"><span style="font-size: 16px;">Though electrical discharge machining (EDM) process is capable for complex and precise machining of materials irrespective of their hardness, it has certain limitations like low material removal rate (MRR), high tool wear rate (TWR), etc. which restrict its application areas. In EDM, material removal from workpiece and tool takes place by means of sparking between them which is a quite complex process. So, it is difficult to predict material removal rate and tool wear rate for various process parameters. In this paper, the experimental data available in existing literature are used to derive empirical formulas for heat distribution factor, crater radius and depth. The tool wear rate is calculated based on these formulas and validated with experimental results. For the selection of optimum process parameters, the proposed theoretical model can be used in EDM process.</span></span></p><p class="MsoNormal" style="margin-top: 6.0pt; margin-right: 0in; margin-bottom: .0001pt; margin-left: 0in; text-align: justify; text-justify: inter-ideograph;"> </p><p class="MsoNormal" style="margin-top: 6.0pt; margin-right: 0in; margin-bottom: .0001pt; margin-left: 0in; text-align: justify; text-justify: inter-ideograph;"><span style="font-family: "Times New Roman", serif;"><span style="font-size: 16px;">Cite this Article Sanghani CR, Acharya GD, K.

Moreover having uplifted to such a sphere of engineering excellence, reverting back to the ages of the bull carts will prove next to impossible thereby compelling us to search for a basket of alternative fuels to derive energy to cater to our needs. Several sources of energy, especially for driving the automotives are being developed and tested. Biodiesel, which is a derivative of vegetable oils, is catching the attention of various nations through its much similar properties to conventional diesel. An experimental investigation was carried out on a small direct injection (DI) diesel engine, fuelling the engine with 20% (B20), 50% (B20), and100% (B100) blending of rapseed oil methyl ester with diesel. The performance and combustion characteristics of the engine at various loads are compared and analyzed. The results showed higher brake specific fuel consumption (BSFC) and lower brake thermal efficiency (BTE) for the rapeseed blends. The engine indicated power (IP) was more for the blends B20, but found to be reduced for the blend B100 when compared to that of diesel. The engine combustion parameters such as pressure crank angle diagram, peak pressure, time of occurrence of peak pressure, net heat-release rate, cumulative heat release, ignition delay and combustion duration were computed. The rapeseed blends exhibited similar combustion trend with diesel. However, the blends showed an early start of combustion with shorter ignition delay period. The study reveals the suitability of rapeseed blends up to B20 as fuel for a diesel engine mainly used in generating sets and the agricultural applications in India without any significant drop in engine performance. </p><p>Cite this Article Ajay Partap Singh, Ajay Trehan.

Manufacturing has been threatened in most of the world except in China and USA, and awaits an action for a speedy recovery. One of the modes to revival is projected through all round cost cutting. To affect cost cutting, it is envisaged that the element of value addition be invigorated, using innovation as input and IIOT (industrial IOT) as the tool. The latter allows manufacturers to assign each of their physical assets a digital identity to maneuver the exact location and condition of those assets in real-time ubiquitously throughout. The trio of Value addition, innovation, and IIOT has been paradigm as an extension of the Joiner’s trilogy model. This set of imperatives of innovation, valuation and IIOT, which serve for cost cutting individually and collectively, may be holistically applied. In that holistic form these have been collated as a tool termed as Innovaluation. By providing for the most ‘valuable’ domains fitting into Joiner’s model—grounded over competence—Innovaluation assures achieving the most of profitability in manufacturing. This is in line with the coveted ‘Make in India’ initiative proposed by our worthy Prime Minister, Shri. Narendra Modi. </p><p class="MsoNormal" style="margin-bottom: .0001pt;">Cite this Article Priyavrat Thareja, Komal Sharma, Samridhi Sharma et al.

These aluminium based composites are being widely used in various applications such as automotive parts, machine cover, frames and ducts etc. Fly ash addition not only makes aluminium harder, stronger, stiffer and more wear resistant but also saves energy consumption and helps in cutting down green house emissions by utilizing almost freely available fly ash which is a waste of thermal power plant and problematic to dispose off. Alfly ash composite is electrically conductive and can be processed by Electro Discharge Machining (EDM). Rough cutting operation in EDM is treated as a challenging one because improvement of more than one machining performance measures viz. metal removal rate (MRR), surface finish (SF) and tool wear are sought to obtain a precision work. Using Taguchi’s parameter design, significant machining parameters affecting the performance measures are identified as discharge current, pulse duration and dielectric flow. It has been observed that a combination of factors for optimization of each performance measure is different. In this study, the relationships between control factors and responses like MRR and SF have been established. </strong></span></span></p><p class="MsoNoSpacing" style="margin-right: 1.35pt; text-align: justify;"> </p><p class="MsoNoSpacing" style="margin-right: 1.35pt; text-align: justify;"><span style="font-family: "Times New Roman", serif;"><span style="font-size: 13.3333px;"><strong>Cite this Article Pankaj Kr Sharma, Shashi Prakash Dwivedi, Amit Kr Sharma et al.

Beds, columns, bases, head stock are known as ‘structure’ in a machine tool. The Lathe Bed should be sufficiently rigid to prevent deflection under tremendous cutting pressure transmitted through the tool-post and carriage to the Lathe Bed. It must be massive with sufficient depth and width to absorb vibration. The ideal material must have high stiffness, good damping capacity, good cast ability, low thermal deformation. Various materials such as; concrete, acralic concrete, wrought steel, Epoxy Granite composite and ceramic resin concrete views as alternate material of cast iron. The main objective of my research work is to decrease the Manufacturing Lead Time of Lathe Bed and reduce Manufacturing Cost with the use of Alternate Material for Lathe Bed. With use of Epoxy Granite as alternate material for Lathe Bed, it decreases Manufacturing Lead Time of Lathe Bed from 7 days to 3 days. So it reduces the Manufacturing Lead Time by 52.14%. It also reduces the Manufacturing cost of existing Lathe Bed from 2937 to 2615 Rs. So it reduces Manufacturing Cost by 10.97 %. Wear rate of the Epoxy Granite is also less than Cast Iron. Epoxy Granite is also unaffected by Environment and Thermal effect.</em></span></span></p><p class="MsoNormal" style="margin-left: .5in; text-align: justify; text-justify: inter-ideograph; text-indent: .5in;"><span style="font-family: "Times New Roman", serif;"><span style="font-size: 14px;"><em></em></span></span><span style="text-indent: 0.5in;">Cite this Article</span></p><p class="MsoNormal" style="margin-left: .5in; text-align: justify; text-justify: inter-ideograph; text-indent: .5in;"><span style="text-indent: 0.5in;">Tapan Pandya, Ashutosh Kumar.

Importance in several damage detection techniques has significantly improved over the past two decades and numerous detection techniques created on model study methods have been established. Crack damage detection and condition observing of configurations have developed ever-increasing concerns. Generally best accessible techniques are constructed on visual review or localized valuation processes such as acoustic, ultrasonic and influence echo. The very vital issues of these techniques are that they usually give qualitative vision of the disorder of constructions rather than quantitative information. In some of techniques, the damage location is a priority and the approachability of damage location is mandatory.
