Aluminium metal matrix composite is main concern of any industrial organization for its survival in the competitive world. In our research experience in area of machining of advanced composites, we have had opportunities to work on some machining of advanced composites issues. This is motivated us to write a book for students of machining of advanced composites concepts and techniques of some major issues on machining of advanced composites. There is also huge gap between the existing text book and journal articles, and we have tried to bridge this gap by suitably mix research articles with prevailing concepts and techniques. during writing this book we kept in mind the necessity of simple presentation throughout the text.
