| Abstract | Grinding vibrations caused by regenerative cutting force and workpiece imbalance are discussed in this study. To regenerate workpiece surface, a grinding wheel is rotated, and pushed towards a rotating workpiece, rubbing and cutting its surface, with regenerative and frictional interactive forces generated. Besides, any mass imbalances of the rotating workpiece or the wheel is another source of vibration. To investigate both effects of the regeneration and the mass eccentricity on the grinding dynamics, a mathematical model with time delays and sinusoid excitation has been developed and analysed. By calculating eigenvalues with continuation scheme, linearly grinding stability is obtained and presented in a lobes diagram, where chatter-free and chatter regions are identified. For chatter without workpiece imbalance, a classical periodic chatter induced by the regenerative effect is found. With imbalance, forced periodic vibration, chatter quenching, quasi-periodic chatter and periodic chatter are obtained in different regions. |

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.
