| Abstract | In order to improve the openness, extensibility and efficiency of Computer Numerical Control (CNC) systems, the architecture and its implementation of an open CNC system for multi-axis machine tools based on The Windows Control and Automation Technology (TwinCAT) and .NET is proposed. In the proposed architecture, the real-time tasks, such as interpolation, real-time cutter compensation, coordinate transformation and motion control, are executed in the real-time kernel provided by TwinCAT, and the non-real-time tasks, such as code interpreter, offline cutter compensation and feedrate look-ahead, are executed in the Human Machine Interface (HMI) implemented on .NET platform. Moreover, an event driven data exchange method is proposed to realize the fast data exchange between the real-time tasks and the non-real-time tasks. The whole system is modularized by several independent modules, the inputs and outputs of which are standardized to improve the convenience of system extension and upgrade. Finally, an open CNC system is implemented based on the proposed architecture, on which experiments are conducted to validate the feasibility and applicability of the proposed architecture and its implementation. |

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.
