| Abstract | An analysis method based on minimizing the axial force by the upper bound method was proposed to obtain the optimal attack angle of the roller in the flow forming process. And the method for minimizing axial force was verified effectively by FEM simulation. The axial force of the roller in the flow forming has an essential effect on producing material build-up and bulge ahead of the roller. The optimal attack angle should minimize the axial force of the roller and also avoid defects such as build-up or bulge effectively, improving the manufacturing accuracy and the surface quality of flow formed product. The possible defects like the material buildup and the spring back or the elastic recovery could be numerically simulated by the FEM. It was shown by the elastic-plastic FEM simulations that the attack angle resulting in the least magnitude of the axial force also resulted in the smallest amount of the material build-up. It is concluded that the simplified calculation of the attack angle is practically useful. |

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.
