| Abstract | Trapezoidal-shaped aluminium wires are in demand for the production of the aluminium conductor steel supported/trapezoidal wire (ACSS/TW) conductor. In this work, it is proposed to manufacture such wires by a multi-pass cold drawing process using a series of shaped dies with an initial aluminium wire, which has an outer diameter of 9.5 mm. The ruled surface partition method is introduced to design the intermediate die profile of the multi-pass cold drawing. It is possible to design the intermediate die profile efficiently according to the suggested reduction ratio and save time regardless of the geometric complexity. A multi-pass drawing machine and a universal testing machine are both used to investigate the drawing process of trapezoidal-shaped aluminium wires. Wire break occurs when a five-pass drawing process is introduced. The six-pass drawing process is suggested to apply in a consideration of die cost. The final production has a good surface finish and a dimensional accuracy, suitable for the production of the ACSS/TW conductor. A finite element method (FEM) simulation approach is used to analyse stress and drawing force for the proposed process. The Von Mises stress values gradually increases and the drawing force values decrease along the pass schedule. The influence of the number of the drawing passes is numerically assessed. The drawing force value and the Von Mises stress value are lower when the number of dies is larger. The numerical compute drawing force of the six-pass drawing process is compared with the experimental ones. A good agreement between the predicted and experimental results can be observed. |

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.
