This volume provides production and mechanical engineers with a wide-ranging account of the techniques of machining that have been developed to deal with new materials. These include polymers, hard metals and ceramics, which are difficult to treat by conventional methods either because of the hardness of components or the high accuracies of machining required. Each chapter includes a discussion of the basic working principles, the removal rates and surface characteristics attainable, and typical industrial applications and machines that are available. Electron, ion beam, electrochemical and laser machining are described in detail. The erosive effects of sparks giving rise to accurately controlled metal removal or electrodischarge machining in which a liquid dielectric such as light oil is the working fluid is next described. Machining by use of plasma arcs, the medium here being an ionised gas, is then discussed. Two non-conventional mechanical methods of machining, involving ultrasonics and water jets, are also explained.Chapter ten of the book describes a range of mainly chemical methods of machining, many of which are the basis for the nano-machining technology needed for the latest generations of computers.

Explaining principles underlying the main micromachining practices currently being used and developed in industrial countries around the world, Micromachining of Engineering Materials outlines advances in material removal that have led to micromachining, discusses procedures for precise measurement, includes molecular-level theories, describes vaporizing workpiece material with spark discharges and photon light energy, examines mask-based and maskless anodic dissolution processes, investigates nanomachining by firing ions at surfaces to remove groups of atoms, analyzes the conversion of kinetic to thermal energy through a controlled fine-focused beam of electrons, and more.
