| Abstract | Manufacturing is an energy-intensive process which could account for significant energy consumption worldwide. Reducing energy consumption on a product level, in addition to a process or facility level, is being seen as a more worthwhile endeavor in light of rising energy costs and environmental concerns. To accomplish this, it is necessary to consider the role of product design in energy consumption. It is possible to design a product such that its manufacture consumes less energy. However, this requires a good model of energy consumption based on the design parameters. A good model must be detailed enough to yield accurate results, but at the same time simple enough such that it can be applied easily and consistently in day-to-day design work. In this paper, we propose an approach for generating such a model by decomposing the manufacturing process into its energy-consuming components. For each component, the relevant design and manufacturing parameters can be elicited by performing sensitivity analysis through analysis and experimentation. Parameters which do not greatly contribute to variance in energy consumption can be held constant, thus simplifying the model. Thus, the simplest possible model can be derived for a specified level of accuracy. We illustrate that critical parameters from energy point of view can differ greatly from process to process by investigating representative manufacturing processes in four general categories: additive, subtractive, forming, and solidification. Finally, we present a case study for injection molding. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
