| Abstract | In this study, a theoretical model was developed to predict cutting forces for machining hard materials that contain more than 0.58% carbon. The model is based on the Oxley machining theory, and it uses the Johnson-Cook empirical constitutive law for the flow stress data or the equation of a hard material and the tool geometric parameter, the nose radius. However, Oxley and his co-workers showed that the flow stress data obtained from high-speed compression tests for a range of only plain carbon steels (less than 0.58% carbon) is suitable for making analytical machining predictions assuming a perfectly sharp tool. In this study, an experiment was carried out to obtain the flow stress in the Johnson-Cook law and the geometry of the tool was simplified to obtain the nose radius. The cutting forces from the developed theoretical model were found to be in good agreement with those measured from an experiment of hard machining with an AISI 4140 steel heat-treated bar. |

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.
