Manufacturing Engineering is a discipline of engineering dealing with various manufacturing sciences and practices including the research, design and development of systems, processes, machines, tools, and equipment. In brief, it is concerned with understanding, analyzing and improving complex industrial, manufacturing and infrastructure systems. Manufacturing Engineering is based on core mechanical engineering skills, adding important elements from mechanics, commerce, economics and business management. It is the most flexible and marketable of all the engineering disciplines. In fact, many engineers that originally study other engineering disciplines end up practicing as Manufacturing Engineers.
