Parametric optimization, especially in machining of non-ferrous alloys seems to be quite rare and needs an immediate attention because of its associated downstream financial and non-financial losses. This book tries to fill the gap and presents an optimization problem of commonly used Al-7020 Alloy. Principles of Response Surface Methodology (RSM) have been implemented through Minitab software to bring necessary multi-response optimization, while turning on a CNC turner. The present study focuses on to enhance Material Removal Rate (MRR) while simultaneously reducing the Surface Roughness (Ra), during turning of Al-alloy. Such opposite natured response optimization is much difficult to achieve, particularly when uncoated carbide tip has been used as a cutting tool. Intensive literature survey helps to pin point parameters like; Cutting Speed, Feed Rate and Depth of Cut as a most critical to machining parameters, as far as effective and efficient optimization of selected responses are concerned. All these control-parameters are directly or inversely related to each other. If the depth of cut is increased MRR increases at the same time we get poor surface finish. Increase in the cutting speed has positive impact on both material removal rate and surface finish. Shortlisted parameters are conflicting, so we have to optimize these for further enhancement of the overall turning performance. At last, the optimized results are verified by using ANOVA as a statistical tool. This book provides quite rare Case-study of multi-response optimization (while non-ferrous CNC turning) to practioners, machinists and SME owners appropriately.

Six Sigma approach is generally employed to improve the sigma level of manufacturing or service processes by reducing their deviations and defects. Six Sigma provides the opportunity to eliminate mistakes, improve morale and save money. Doing things right in first time and keeping them consistent is the only idea behind Six Sigma. Its fundamental objective is to achieve customer satisfaction with continuous improvement in quality and productivity. Mostly we are emphasizing on various tools or techniques being used during DMAIC projects and almost ignore the procedure to execute different phases of the Six Sigma project. This book provides unique step by step methodologies to perform Define, Measure, Analyse, Improve and Control phases of a Six Sigma project, respectively. An empirical investigation has been carried out in a make-to-order type (medium sized) foundry and Six Sigma is successfully implemented by decreasing the scrap of piston castings, appreciably. The book focuses on scrap reduction specifically in Indian foundries and tries to find out the reasons of low productivity index. It also tends to shatter the various phobias of SMEs in context of Six Sigma by validating the compatibility of proposed methodologies through a successful case study in Indian foundry environments.

Africa’s dire need to industrialize is universally acknowledged and it is evident that the continent’s vast mineral resources can catalyze that industrialization. This requires the promotion of local beneficiation and value addition of minerals to yield materials on which modern Africa’s industry and society can rely. This book is, therefore, about transforming Africa’s comparative advantages in minerals into the continent’s competitive edge regarding materials. Mineral beneficiation and value addition form the basis and provide opportunities for mineral-driven Africa’s industrialization. The scope of the book is three-fold with inter-connected relationships: Information, Technical, and Policy oriented. It will be a useful reference material for mining undergraduate students on beneficiation and value addition of each of the minerals found in Africa. The book, while presenting a broad overview of beneficiation and value addition of Africa’s minerals, provides crucial starting material for postgraduate research students and R&D institutions who wish to delve into more advanced methods of extraction and utilization of mineral-derived materials that are in Africa for the purpose of industrialization of the continent.

As per present manufacturing scenario, focus of all manufacturing organizations is to produce good quality product with a minimum cost. CNC turning process is the most common machining process that is used in now days. Present work has been done to optimize the machining parameters for material AL 6061 like depth of cut, feed rate and cutting speed. As per the requirements of the manufacturing sector there is huge application of AL6061. Therefore it becomes necessary to optimize the various machining parameters of AL6061.In present work CNC Turning parameters has been optimized for AL 6061 using Response surface Method (RSM). Initially after selecting the parameters and their levels individually a RSM matrix has been prepared. After words experiments were performed as per RSM matrix. Material removal rate and surface roughness was recorded as per the defined set of experiments of matrix. Afterwards significance of individual parameters like Speed, feed and depth of cut has been noticed at 95% confidence level by applying regression tests.Further the optimized results have been verified using One Way ANOVA. MINITAB 16 software is used for the formulating the matrix and for the analysis of regression and response surface methodology.

The book contains Optimization of Multi response of Turning Process Parameters by Using Tool Inserts, now a days mostly used optimization technique which is better than single response optimizing technique because all the output is affected at a time by all the input factors. The objective of this book is to determine the optimal setting of cutting parameters speed (N)m/min, depth of cut(d) mm, feed(f)mm/rev, Nose Radius(r)mm, variation amplitude(mm/sec2), vibration frequency(kHz) in Cutting tool inserts to minimize surface roughness (Ra) and to increase the Tool life. In this book the experiment has been carried out on CNC (SPINNER 15) lathe in dry, Wet and MQL (Minimum Quantity Lubrication) cutting Condition turning of a commercially used EN 24 grade steel as a work material and carbide insert tool (CNMG120408 CNMG120412). This book highlights use of Taguchi experiment design to optimize the multi response parameters on turning operation. For this experiment Taguchi design of experiment was carried out to collect the data for surface roughness and tool vibration. The results indicate the optimum values of the input factors and the results are conformed by a confirmatory test. This book describes use and steps of Taguchi design of experiments and orthogonal array to find a specific range and combinations of turning parameters like cutting speed, feed rate and depth of cut, Nose Radius and Cutting condition to achieve optimal values of response variables like surface roughness, tool life, material removal rate in turning of Split Bush of EN24 Material.

Manufacturing a product is not difficult, the difficulty consists in manufacturing a product of high quality, at a low cost and rapidly. Drastic technological advances are changing global markets very rapidly. In such conditions the ability to compete successfully must be based on innovative ideas and new products which has to be of high quality yet low in price. One way to achieve these objecti ves would be through massive investments in research of computer based technology and by applying the approaches presented in this book. The First International Conference on Advanced Manufacturing Systems and Technology AMST87 was held in Opatija (Croatia) in October 1987. The Second International Conference on Advanced Manufacturing Systems and Technology AMSV90 was held in Trento (Italy) in lune 1990. The Third, Fourth, Fifth and Sixth Conferences on Advanced Manufacturing Systems and Technology were all held in Udine (Italy) as follows: AMST93 in April 1993, AMST96 in September 1996, AMST99 in June 1999 and AMST02 in June 2002.
