Sesha Saty, “Numerical modelling of thermal phenomenon in friction stir welding of aluminum plates”, IOP Conference Series: Materials Science and Engineering, vol. 149. p. 012208, 2016.[Abstract]


Friction stir welding (FSW) is a solid state welding process with potential to join materials that are non weldable by conventional fusion welding techniques. The study of heat transfer in FSW aids in the identification of defects like flash, inadequate heat input, poor material flow and mixing etc. In this paper, transient temperature distribution during FSW of aluminum alloy AA6061-T6 was simulated using finite element modelling. The model was used to predict the peak temperature and analyse the thermal history during FSW. The effect of process parameters namely tool rotation speed, tool traverse speed (welding speed), shoulder diameter and pin diameter of tool on the temperature distribution was investigated using two level factorial design. The model results were validated using the experimental results from the published literature. It was found that peak temperature was directly proportional to tool rotation speed and shoulder diameter and inversely proportional to tool traverse speed. The effect of pin diameter on peak temperature was found to be trivial.

Friction stir spot welding (FSSW) is a recent joining technique developed for spot welding of thin metal sheets. This process currently finds application in automotive, aerospace, marine and sheet metal industry. In this work, the effect of FSSW process parameters namely tool rotation speed, shoulder diameter and dwell time on Tensile shear failure load (TSFL) is investigated. Box-Behnken design is selected for conducting experiments. Fuzzy based soft computing is used to develop a model for TSFL of AA6061 joints fabricated by FSSW. The interaction of the process parameters on TSFL is also presented.

Cleaner Production (CP) strategies are basically concerned with environmental sustainability, maximization of waste reduction, recycling, and reuse. This research has the purpose to identify the use of resources and sources of pollution in a cleaning equipments manufacturing and testing factory. The principles of clean technology are applied at the same factory for reducing air pollution and waste water standardization. The research focuses on the effect of Clean Technology (CT) implementation on different causes of air pollution and wastewater. The main application of clean technology is to minimize air pollution in the welding area (production area), and to develop a better system for wastewater treatment. Installation of local exhaust ventilation with a proper design can prevent the emission of welding fumes to the atmosphere and implementation of a treatment plant will help for the reuse of water. Both can give the company a better environment friendly and working atmosphere. A case study is carried out in a cleaning equipment manufacturing company. © Research India Publications. More »»

M. Nithin and Dr. Gokulachandran J., “Risk assessment and management in a manufacturing industry”, International Journal of Applied Engineering Research, vol. 10, pp. 17303-17314, 2015.[Abstract]


An industry is always prone to hidden risks. This study provides an overview on the identification, assessment and management of risks in a manufacturing industry. A conceptual model was developed for the effective Risk Management. A case study was performed for Risk identification through observation and interview with company personnel and Risk assessment by a) Risk classification and b) Risk prioritization using Analytical Hierarchy Process (AHP). Suggestions for risk control were also put forward to the company along with the conceptual model. In this study, suggestions were also made to document the Risk identification, Risk assessment, and Risk control continuously for every update. The suggestions for effective risk control, were made based on the severity of each risk and cost effectiveness. © Research India Publications. More »»

Reuse of partially worn-out materials and parts is a philosophy now being applied in all manufacturing industries to achieve the goal of green manufacturing. High productivity cutting tools used in manufacturing industry are generally expensive. As such, the accurate assessment of remaining useful life (for reuse) of any given tool is of great significance in any manufacturing industry. This exercise will in turn reduce the overall cost and help achieve enhanced productivity. This paper reports the use of two soft computing techniques, namely, neuro fuzzy logic technique and support vector regression technique for the assessment of remaining useful life (RUL) of cutting tools. In this work, experiments are conducted based on Taguchi approach and tool life values are obtained. Tool life values are predicted using the aforesaid two soft computing techniques and RUL obtained from these values are compared. More »»

In manufacturing industry, cutting tools are often discarded when much of their potential life still remains. Predicting the remaining useful life of the partially degraded components and putting them to use will help to save natural resources to a great extent. This saves manufacturing cost and protects environment. The main objective of this research is to develop a comprehensive methodology to assess the reuse potential of carbide-tipped tools. In this work, based on Taguchi approach, experiments are conducted and tool life values are obtained. The analysis is carried out in two stages. In the first stage, a regression model is proposed for the prediction of remaining life of carbide-tipped tools. In the second stage, an artificial neural network model is developed for predicting tool life. The results of both models are compared. © 2012 Inderscience Enterprises Ltd.

A second model is developed based on fuzzy logic method for predicting tool life. The results obtained from fuzzy method are compared with regression model. The results of the fuzzy model is found to be more closer to experimental values More »»

Purpose - To provide a modified orthogonal array-based model for enabling the researchers and practitioners to exploit the technique, "design of experiments" in an agile manufacturing environment. Design/methodology/ approach - The characteristics of Taguchi's off-line models and agile manufacturing were studied. A theoretical model of modified orthogonal array-based experimentation was designed. This model was subjected to implementation study in an Indian pump-manufacturing company. Findings - The model contributed in this paper has shown its feasibility in achieving quality in agile manufacturing environment. Research limitations/implications - The authors are residing in an Indian city where the majority of the companies have not adopted agile manufacturing criteria. Hence, it was not possible to carry out implementation study in an agile manufacturing company. Future researchers should examine the practical validity of the proposed model in agile manufacturing companies. Practical implications - Since the manufacturing organizations are fast becoming agile, due to the customers' dynamic demands coupled with competition, the traditional quality improvement techniques are becoming obsolete. The model contributed in this paper is found to be useful in achieving continuous quality improvement in AM environment. Hence the model would be a useful technique for today's practitioners whose activities are increasingly focused towards achieving agility in manufacturing. Originality/value - The literature survey covering articles on agile manufacturing indicates that no researcher or practitioner has contributed a model that would exploit the technique, "design of experiments" in an agile manufacturing environment. Hence the proposed model is expected to be of high value for researchers and practitioners to explore the way of achieving continuous quality improvement in agile manufacturing environment. © Emerald Group Publishing Limited.
