Manufacturing Manufacturing can be said in a broad sense to be the process of converting raw materials into usable and saleable end products by various processes machinery and operations. The important function of manufacturing is therefore to add value to the raw materials. It is the backbone of any industrialized nation. Without manufacturing few nations could afford the amenities that improve the quality of life. In fact generally the higher the level of manufacturing activity in a nation the higher is the standard of living of its people. Manufacturing should also be competitive not only locally but also on a global basis because of the shrinking of our world. The manufacturing process involves a series of complex interactions among materials machinery energy and people. It encompasses the design of products various processes to change the geometry of bulk material to produce parts heat treatment metrology inspection assembly and necessary planning activities. Marketing logistics and support services are relating to the manufacturing activity. The major goals of manufacturing technology are to improve productivity increase product quality and uniformity minimize cycle time and reduce labor costs. The use of computers has had a significant impact on manufacturing activities covering a broad range of applications including design of products control and optimization of manufacturing processes material handling assembly and inspection of products. 2 1 Fundamentals Unit Processes in Manufacturing The central part of manufacturing activity is the conversion of raw material to component parts followed by the assembly of those parts
