| Abstract | An attempt was made in the present study to apply damage mechanics to investigate the polycrystalline cubic boron nitride (PCBN) tool failure mechanisms in face milling of hardened steel. Experimental phenomenon relating to damage accumulation was found by means of analyzing the tool wear evolution and macroscale failure of the cutting tool. Damage equivalent stress was used as an indicator to reveal the tool failure mechanisms under different cutting conditions. Because of the larger value of damage equivalent stress, there was greater likelihood of tool fracture in down milling than that in up milling. Deflection of the shear angle changed the tool stress component and distribution substantially in up milling, leading to the emergence of the peak value of damage equivalent stress in spite of lower values of cutting force and tool temperature. Calculated damage equivalent stress and tool lives obtained in milling tests were compared and analyzed. It was found that damage equivalent stress can be used as an effective tool to analyze the tool failure mechanisms and assess the optimum cutting condition. |

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.
