New materials and their machining

Sophistication in materials applications is the basis of technological prog ress and therefore there is a continuous search for new materials: i.e. mat erials that are light in weight, strong, tough, corrosion resistant, durabl e, wear resistant, resistant to various hazards of nature, safe for our hea lth, etc. The new generation of materials with improved properties pose pro blems during machining because of their material structure, and hence they require new machining processes. The interactions between the toot and work piece and also between the various micromechanisms involved in material rem oval during ductile regime machining of new materials, such as glasses, cer amics, and semiconductors, are discussed in this paper.
