| Abstract | This paper presents a preliminary investigation into a method for reducing servo delays that occur after the execution of rapid positioning commands in computer numerically controlled (CNC) machines. A model of the machine’s dynamics is used to predict the servo error resulting from a prescribed rapid positioning command. Based on this information, the reference path is extended by an amount calculated to ensure that the predicted error falls within a user-specified threshold in the shortest possible time. The proposed method is shown in simulations to significantly shorten rapid positioning time compared to the industry-standard approach of compensating for servo delays by pausing motion until servo errors fall within user-specified thresholds. However, experiments reveal the need for further research to enhance the versatility and robustness of the method. |

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.
