This new edition of CAD/CAM/CIM has been incorporated with a few additions to provide the readers information on latest developments in this field. Computer integrated manufacturing started with software-based automation in combination with hardware. Current trends in manufacture such as digitization, including the shift to mass customization, led to significant changes in manufacturing. The details of this digital transformation have been dealt in detail in several chapters of this book. We are currently going through the fourth industrial revolution. Thanks to the resurgence of robotics and widespread adoption of artificial intelligence, machine learning, data science and analytics and cloud computing. This development as far as manufacturing is concerned is widely referred as Industry 4.0. The framework of the industry 4.0 concept has a long history starting with stand-alone mechatronic systems leading to cyber-physical and eventually autonomous systems to the final degree of autonomation. Manufacturing engineers need to have a comprehensive understanding of computer networking. Apart from actual manufacturing, acquisition of manufacturing data is very important for downstream processing of manufacturing information. Today efficient operation of manufacturing requires communication between machines, robots and other production equipment. Technologies like MT-Connect have been developed to enable communication between manufacturing equipment. This book is written for mechanical and manufacturing engineering students of undergraduate and postgraduate courses.
