Abstract | There is a growing demand for industrial products that are capable of multi function as well as smaller foot print Smaller foot print results in lower material cost as well lower energy consumption Several manufacturing processes have been developed for producing miniature products and features Producing micro hole is one of the major requirements in most products such as fuel injector nozzles fluidic filters biomedical filters and ink jet printer nozzles newlineHowever conventional machining process is not capable unless micro tools are used and this is possible only with micro machine tools The same applies for non conventional machining processes such as EDM ECM USM and others Although EDM and ECM are designed for the macro domain they can be used for producing micro features by modifying the process parameters used In the micro domain Micro EDM has been selected for micro hole machining for its advantages such as machining of hard materials concave shapes and intricate 3D structures Based on the advantages the experiments are planned to study the performance of micro EDM machine The process parameters such as gap voltage capacitance have been varied to study the output responses namely Material Removal Rate Tool Wear Rate Overcut and Taper angle Experiments are planned with the Stainless Steel of grade 304 workpiece of 200μm thickness and tool electrode of diameter 500 μm |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
