New Materials and their Machining

Sophistication in materials applications is the basis of technological progress and therefore there is a continuous search for new materials: i.e. materials that are light in weight, strong, tough, corrosion resistant, durable, wear resistant, resistant to various hazards of nature, safe for our health, etc. The new generation of materials with improved properties pose problems during machining because of their material structure, and hence they require new machining processes. The interactions between the tool and workpiece and also between the various micromechanisms involved in material removal during ductile regime machining of new materials, such as glasses, ceramics, and semiconductors, are discussed in this paper.
