Minimum quantity lubrication (MQL) is currently a widely used lubricating technique during machining, in which minimum amount of lubricant in the form of mist is delivered to the machining interface, thus helps to reduce the negative effects caused to the environment and human health. Further, to enhance the productivity of machining process specifically for hard-to-cut materials, nano cutting fluid (suitably mixed nano materials with conventional cutting fluid) is used as an alternative method to conventional lubrication (wet) in MQL. In this study, h-BN nano cutting fluid was formulated with 0.1% vol. concentration of h-BN in conventional cutting fluid (Servo- ‘S’) for NCF-MQL technique and its tribological behaviors on machining(turning) performance of Inconel 625 were studied and compared with other lubricating conditions (dry, wet, MQL conventional). The tribological effects were analyzed in terms of tool wear analysis, chip morphology along with statistical analysis for machined surface and evolved cutting forces during machining. The optimal input machining parameters for experiments were defined by the use of Taguchi and Grey relational based multi response optimization technique. Finally, the tribological study shows that the use of h-BN NCF-MQL is a viable and sustainable option for improving machining performance of hard- to- cut material like Inconel 625.

Solar dryers are one of most efficient devices for drying food and other products. These devices are eco-friendly and need solar energy for their operation and which is available freely and abundantly at almost every place. These are simple devices which do not need use any fossil fuel for their operation, which are expensive, exhaustive in nature and are not eco friendly. Several fresh food products and other items are dried for preservation and utilization for longer period of time. In recent times, with the development in this technology, the solar dryers are becoming well equipped with efficiency increasing add-ons which give higher performance. Several experimental studies have been carried out to mitigate the time consumption and increasing the productivity of solar dryers. Optimization of solar dryers is done to increase their workability increasing accuracy and reducing drying time and cost investment. In order to optimize the complete setup several techniques could be used to get the optimum results. In the present work Taguchi optimization technique was applied for experimental analysis of solar dryer which was used to dry potatoes. The results thus obtained showed the best configuration comprising air velocity, air flow and humidity required to dry potatoes

Forming Simulation

Metal forming plays a very important role in the manufacturing. Simulation of manufacturing process aids in the improvement of quality, reduce energy and resource consumption and helps in visualization of the process. The design of experiment helps in optimization of the parameters in any processes. In this paper, Taguchi optimization technique is used to predict the best results for the given inputs such as roller diameter, friction value, velocity of the rollers and percentage reduction to the forming process and get the optimized values for spread, hardness, effective stress, power required, strain rate and torque using the manufacturing simulation software. It is found that the important parameter is percentage reduction affecting the effective stress. Optimal parameters with desirability value of 0.87 have been obtained.

Severe plastic deformation (SPD) Processes is to be determined as metal forming processes in which a very large plastic strain is imposed on a bulk process in which to make an ultra-fine-grained metal. Generating an ultrafine grained metal is to allow lightweight parts by using high strength metal for the safety and reliability of micro-parts and for eco-friendly, is the main intention of SPD Processes. In Severe plastic deformation processes (SPD), repetitive corrugation and straightening (RCS) are one of the new technical processes, in which the grain size is reduced to ultrafine grain size then the strength of copper is going to be increased by using this process in this project. The Taguchi optimization technique is utilized with conventional orthogonal array L9, in which to determine the process parameters are statistically significant on hardness. Finally, the verification test was carried out to investigate optimization enhancements.

Polar Code

Mobile communications have seminal importance in telecommunication systems. Thrust challenges in optimization area like capacity to scale up in channels, coverage area and integration of newer techniques with minimum design efforts are targeted in this work. This article proposes a novel technique of configuring the present decoder with Euclidian distance polar-code decoding method at low hardware efforts. The Taguchi optimization technique based on orthogonal array method for polar-code is employed to carry out an experimental design to achieve parameter optimization. This method helps to cram interaction between process parameters. Taguchi optimization analysis of polarization effect of polar code and 8 PSK higher modulations resulted into an increase in channel utilization and bandwidth. The experimentation results proved a low SNR of 9.8 dB and efficient channel utilization of 2.9956 bits/Hz for desired BER of 10- 4, reducing network congestion by 1.5 times. At the same time, yield in bandwidth has sunk from 25 KHz to 16.66 KHz by paying minimum penalty of 1.496 dB in required SNR.
