| Abstract | In this paper, the cutting surface burning problems of high-speed wire electrical discharge machining (HS-WEDM) under the condition of large energy are investigated, and the causes of the surface burn are analyzed. According to microscopic morphology, element composition of the cutting surface, and analysis of discharge waveform in the processing, the causes of the surface burn are as follows. The working medium between electrodes rapidly vaporizes under the condition of large energy. In addition, discharging lacks a full working medium, which results in failure to remove ablation products and in sintering on the surface of the workpiece. Notably, the surface burning appears to be asymmetric because of gravity. The influences of forward and reverse cutting of HS-WEDM, duty ratio, and wire speed on the surface burn are also analyzed. A method for adjusting forward and reverse duty ratio to improve the surface quality under large energy cutting is introduced. A new mode of variable speed reciprocating wire electrical discharge machining is designed, which can guarantee machining efficiency and can reduce surface burn. |

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.
