ABSTRACT
The weight of finished components/products plays a critical role in assessing the efficiency of the manufactured product in every research sector such as transportation, sports, biomedical, and electronics. In the case of transportation, the dangerous emission of gases can be minimized by reducing the weight of the vehicle or plane or ship. Many governments around the world have imposed very strict norms on the hazardous emissions of gases, especially coming from the transport and manufacturing sectors. Hence, using light alloys such as aluminum, magnesium, and titanium in manufacturing is therefore highly encouraging for researchers. Machining is the most widely used process that is used for manufacturing components. Hence, knowledge of material machinability is important for any machining process such as turning, milling, drilling, etc. This chapter reviews the machinability of light alloys having base materials of aluminum, magnesium, and titanium. It includes the influence of the alloys during machining on the cutting temperature, cutting forces, choice of tool, and tool wear. The recent trend in the machining process, such as cryogenic machining of these alloys, is also presented in the chapter.
