This book reports on cutting-edge research and technologies in the field of advanced manufacturing and materials, with a special emphasis on unconventional machining process, rapid prototyping and biomaterials. It gathers contributions to the International Conference on Manufacturing Engineering and Materials (ICMEM 2020), which was originally planned in June 2020, but will actually take place in 2021, in Novy Smokovec, Slovakia, because of the Covid-19 pandemic. Despite the challenging times, submitted contributions were peer-reviewed, and upon a careful revision, included in this book, which covers advances that are expected to increase the industry's competitiveness with regard to sustainable development and preservation of the environment and natural resources. Condition monitoring, industrial automation, and diverse fabrication processes such as welding, casting and molding, as well as tribology and bioengineering, are just a few of the topics discussed in the book's wealth of authoritative contributions. A special emphasis is given to problems connected to climate change and solution manufacturer and engineers may adopt and develop to prevent and cope with them.

This book reports on cutting-edge research and technologies in the field of advanced manufacturing and materials, with a special emphasis on unconventional machining process, rapid prototyping and biomaterials. Based on the International Conference on Manufacturing Engineering and Materials (ICMEM 2018), held in Novy Smokovec, Slovakia on 18-22 June 2018, it covers advances in various disciplines, which are expected to increase the industry's competitiveness with regard to sustainable development and preservation of the environment and natural resources. Condition monitoring, industrial automation, and diverse fabrication processes such as welding, casting and molding, as well as tribology and bioengineering, are just a few of the topics discussed in the book's wealth of authoritative contributions.

The objective of our study is to look for various mechanisms of tool life in order to understand it and subsequently use them to find out the various parameters of tool wear in rock cutting. This will lead to the development of an understanding of the tool wear parameters which one can control in order to increase the tool life as per the convenience in machining. On the basis of the knowledge-base one has to try to maintain the tool life in order to favorably increase the material removal rate. This book also dealt with the experimental study of dry drilling in basalt and related tool wear. It is found that flank wear, VB, and cutting edge radius, CER, wear rates increase with rock strength, VB-wear rates and CER-wear rates exhibit opposite trends in their dependence on the remainder of the cutting parameters.

In this era of"think small"or"think big"one would instinctively simply scale down or scale up the size of all machineries to a device to make it small or big.It is true that nothing is there to stop one from downsizing or amplifying the device components to make the device undersized or oversized. Some serious fall out wiill be there of scaling down or scaling up many physical quantities.This book will present, with selected cases, the scaling laws that will make engineers aware of both positive and negative physical consequences of scaling down or scaling up machines and devices.Miniaturizing or amplified machines and physical systems is an ongoing effort in Human civilization.This endeavor has been intensified in recent years as market demands for: Intelligent, Multi-functional and Low cost consumer products has become stronger than ever.The only answer to produce these consumer products is either to wrap up many components into the product-making it obligatory to miniaturize each individual component or make it amplified with gigantic construction.Miniaturization or amplification of physical systems is a lot more than just scaling down or scaling up device components in sizes.

Rapid Prototyping is now a technology of two and half decades old. It is now high time to critically investigate the candidate rapid manufacturing processes which can be seamlessly interfaced with RP processes. In this book an attempt has been made to identify such suitable production processes for customized manufacturing methodology.The final chapter of the book discusses about the interfaces of some suitable manufacturing processes with the RP methodology. These interfaces are some time very much problematic and there are not at all seamless and hassle free in most of the cases. These interfaces are crucial for the success, survival and efficacy of the rapid manufacturing processes.In a nut shell the book exposes a reader about the developments of RP and RM processes for customized manufacturing domain. The author will feel deeply honored even a small number of readers are enlightened in this fascinating world of Rapid Prototyping and Rapid Manufacturing.

In view of the rapid changes that are taking place in Indian economy due to the policy of liberalization and the fierce global competition, the Indian manufacturers have to adopt themselves to the changing scenario. Indian handicrafts and products from its rural industries have a large global market and can change the balance of payment positions of India. Also small and medium scale industries including ancillaries who are traditionally suppliers of simple and rough machined components are now being encouraged to involve themselves in highly sophisticated products. The main objective is to identify, develop and exploit new technologies that can bolster productivity, quality and commercial viability without costing the environment, i.e. to develop environment friendly engineering processes on the principle of agile manufacturing for which the best candidates are rural and medium scale industries of India.
