| Abstract | A fine processing method for precision balls is developed based on eccentric plate and variable-radius V-groove (EPVV) method. The ball-spin angle is a key kinematical parameter affecting the generation of spherical surface. The geometry and kinematics of workpiece was theoretically analyzed, and then ball-spin angles θ and γ and trajectory on the spherical surface can be obtained. The standard deviation (SD) of trajectory density is used to quantitatively evaluate the trajectory distribution. Under the condition of equal rotation speeds of upper and lower plates, the ball-spin angles θ and γ can vary continuously within a range of 0°–180° and the trajectory can be distributed over the entire spherical surface after a processing cycle, which was proved by an experimental observation. From the result of polishing experimental in which the deviation of surface roughness (R a) at different positions on single ball surface decreased from 38 to 11 nm, the trajectory distribution of EPVV method was demonstrated to be improved. The effects of polar radius of V-groove curve, eccentricity, and V-groove half-angle on the ball-spin angles θ and γ and trajectory distribution were also investigated. |

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.
