Surface integrity of electrodischarge machined cavities for different depths and radii

Abstract With the increasing need to reduce manufacturing time, the demands on machining operations on hardened steel have greatly increased. Due to higher mechanical forces needed to machine hardened steel, tools tend to wear out quicker, increasing costs. One alternative that has been applied is electrodischarge machining, which is widely applied due to its versatility and possibility of machining complex shapes on any conducting material, independent of its mechanical properties. However, due to the higher temperatures resulting from the electrical discharges, the machining conditions greatly affect the surface integrity, causing undesirable effects that may cause component failure during service. In addition, the electrode characteristics, such as shape, material and geometries, may greatly affect the machined surface, leading to greater or smaller machined surface damage. In this context, this work presents an evaluation of the surface integrity of AISI P20 mold steel after machining, using electrodes with different radii and machining depths, statistically evaluated through analysis of variance. Different regions of the cavity were evaluated, and results showed that machining depth had significant effect on the heat-affected zone thickness.

About National Digital Library of India (NDLI)
NDLI logo

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.
