Nowadays, machining is one of the most important of manufacturing processes in which a cutting tool or other techniques are used to remove excess material from a workpiece so that the remaining material is the desired part shape. Forming technologies includes a large group of manufacturing processes in which plastic deformation and other techniques are used to change the shape of workpieces. Machining and forming technologies can be applied to a wide variety of materials, namely, metals, polymers, ceramics, composites, biomaterials, nanomaterials. This book focuses on machining and forming technologies.
