Manufacturing – Need and concept
The progress and the prosperity of human civilization are governed and judged mainly by improvement and maintenance of standard of living through availability or production of ample and quality goods and services for men’s material welfare (MMW) in all respects covering housing, clothing, medicine, education, transport, communication and also entertainment. The successful creation of men’s material welfare (MMW) depends mainly on
• availability of natural resources (NR)
• exertion of human effort (HE); both physical and mental
• development and use of power tools and machines (Tools),
This can be depicted in a simple form,
MMW = NR(HE)^TOOLS
where, NR: refers to air, water, heat and light, plants and animals
and solid and liquid minerals
TOOLS: refers to power plants, chemical plants, steel plants,
machine tools etc. which magnify human capability.
This clearly indicates the important roles of the components; NR, HE and TOOLS on achieving MMW and progress of civilization.
Production or manufacturing can be simply defined as value addition processes by which raw materials of low utility and value due to its inadequate material properties and poor or irregular size, shape and finish are converted into high utility and valued products with definite dimensions, forms and finish imparting some functional ability. A typical example of manufacturing, A lump of mild steel of irregular shape, dimensions and surface, which had almost no use and value, has been converted into a useful and valuable product like bolt by a manufacturing process which imparted suitable features, dimensional accuracy and surface finish, required for fulfilling some functional requirements.

Manufacturing Processes
This refers to science and technology of manufacturing products effectively, efficiently, economically and environment-friendly through
• Application of any existing manufacturing process and system
• Proper selection of input materials, tools, machines and environments.
• Improvement of the existing materials and processes
• Development of new materials, systems, processes and techniques
Manufacturing Science and technology are growing exponentially to meet the growing demands for;
(i) Increase and maintenance of productivity, quality and economy specially in respect of liberalisation and global competitiveness.
(ii) Making micro and ultra precision components for the modern electronics, computers and medical applications.
(iii) Processing exotic materials, coming up with rapid and vast advent of science and technology like aerospace and nuclear engineering.
