Abstract: With a rapid change in technology especially in the manufacturing sector, customers are demanding more value, less risk, and better integration of products, hence there is a need to change the manufacturing strategies, which can result in improved performance thereby meeting the customer demands. This paper critically reviews a new area to overcome the above problem called “E – Manufacturing” which can integrate customers, products and suppliers with the help of Internet Technology. The concept of E - Manufacturing, its development, tools and potential benefits are discussed along with application examples on Automobiles. Areas like E – Maintenance, E – Diagnostics, E – Business related to E – Manufacturing is also discussed. By adopting such a manufacturing technique zero downtime, reduced product error, customer satisfaction, quick manufacturing changes can be accomplished. In addition the concept of E-Manufacturing applied to the manufacture of gears is also discussed there by providing better understanding of this process.

like ERP, MES, SCADA, and even newer acronyms like Enterprise Asset Management (EAM) and Product Lifecycle Management (PLM) are communicating with each other, and sharing data through internet connections.

II. EVOLUTION OF E MANUFACTURING For decades, the dominant manufacturing model was based on principles of mass production [2]. Standardized parts and processes made economies of scale achievable, but limited design flexibility and customization. The outsourcing and lean manufacturing movements of the 1980s and 1990s drove the emergence of a new paradigm, termed the Quality Management era. Manufacturing companies, particularly large Original Equipment Manufacturers’ (OEM) outsourcing shifts critical elements of the design and production process onto a manufacturer’s supply chain. The lean manufacturing movement places a premium on time and inventory reduction. Combining the attributes of the Quality era suggests a very different business model for manufacturing – enterprise integration or E-Manufacturing. In the E-Manufacturing era, companies will be able to exchange information of all types with their suppliers at the speed of light. III. E MANUFACTURING E-Manufacturing can be most cogently and generally described as the application of the Internet to Manufacturing [3], further E-Manufacturing is becoming popular with the increased use of the internet. Due the widespread availability of the Internet; large-scale distributed projects in manufacturing are becoming popular. It is the methodology and framework for collaborative Virtual Manufacturing. The ability to exchange information and automate manufacturing processes forms the building blocks of the virtual manufacturing companies of the near future. It covers all aspects of manufacturing - sales, marketing, customer service, new product development, procurement, supplier relationships and logistics manufacturing strategy development and so on. As a result, it is now so much easier to allow certain people gain access to certain sections of the system, according to whatever criteria they like; maintenance people need certain parts of the data, but not others; operators would be able to access a limited number of devices; managers would be allowed to monitor, but not change anything, etc. New technologies such as the Extensible Markup Language (XML) are now making it easier to share data between different application programs, and to set up computers to take actions based on criteria ‹ for instance, to order supplies when inventories reach a critical low point.
