Abstract | Because of the special forging material and complex pipe structure of the main pipe of the AP1000 nuclear power plant, a single general equipment can not meet the requirements of machining the inner hole of the bending section. At present, most of them adopt the method of approaching theoretical dimension by manual grinding, which makes the labor intensity of workers large, the work cycle is long, and it is difficult to ensure the machining accuracy of the workpiece. In view of the practical difficulties in processing the elbow inner hole of nuclear power main pipeline, the copying processing equipment is designed. The fixed circular arc guide rail is used in the equipment. The arc curvature of the guide rail is the same as that of the workpiece. The boring cutter head moves axially along the fixed circular arc curvature guide rail for copying boring. After testing, it fully meets the requirements of the shape, position and size accuracy of the inner hole in the bending section of the nuclear power main pipeline. The method is efficient, accurate and innovative, and provides reference for similar product processing schemes. |

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.
