Throughout history, cutting has been at the heart of production. Metals are subjected to a variety of techniques, which can be classified according to the physical phenomenon involved. Many key industrial components require machining to get their final shape, exact dimension, and acceptable surface polish. Machining is a crucial finishing procedure in which tasks are created to the desired dimensions and surface polish by gradually eliminating extra material from the prepared blank in the form of chips using cutting tools that are pushed past the work surfaces. Chips are formed during all machining processes by deforming the work material on the job's surface with the use of a cutting tool. Chips come in a variety of forms and sizes, depending on the tool geometry, cutting conditions, and work material.
This book elucidates the concepts and innovative models around prospective developments with respect to metal cutting. It talks in detail about the various concepts and theories related to this subject. It deals with calculating space angles in a plane, curved edge drills and space angle problems. It also explores energy dissipation in metal cutting, modelling modern cutting tools, free cutting tool design, theory of regenerative chatter and NC machine tools. The aim of this book is to equip students with the fundamental techniques and methods used in this area. Through this book, we attempts to further enlighten the readers about the new concepts in this field. Coherent flow of topics, student-friendly language and extensive use of examples make this book an invaluable source of knowledge. For someone with an interest and eye for detail, this book covers the most significant developments related to this field.
