| Abstract | A large number of coordinate points is available after digitizing a profile, a surface, or generating the points of the function that define the surface or the profile (if an equation to generate these points is available). These coordinate points are grouped according to the strategy followed for the digitization or the generation. But not all the coordinate points are equally important: More coordinate points are needed in the zones where the curvature is larger, in contrast to the zones where the curvature is smaller. A new selection method of coordinate points is presented in this study. It is based on the maximum allowed chord error. This method simplifies the selection of the important coordinate points for the shape reconstruction with a computer-aided design program or for the computer numerical control (CNC) mechanizing, using either less information, smaller number of points, or NC program lines. To accomplish this objective, any programming language can be applied. An Excel macro and MATLAB have been used in this study. This is interesting both in high-speed CNC machines and in old equipment. The first ones have “look ahead” benefits, because the number of blocks in the NC program are read in advance. Therefore, if a smaller number of lines are needed for the same required precision, the process speed will be higher. The use of old machines will also be improved by the smaller number of lines to process. It must be noted that this process is as fast as the slowest of its elements. |

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.
