| Abstract | Numerical studies on the cutting process of brittle materials have not previously been conducted, due to the difficulties involved, which stem from the differences to their fracture mechanisms compared to those of ductile materials. The purpose of this study is to propose and implement a numerical cutting model that is able to represent the removal mechanism in brittle material. For this purpose, cutting behavior was simulated using the smooth particle hydrodynamics (SPH) method and the Johnson-Holmquist material model. The numerical cutting model of brittle materials proposed here was able to realize the propagation of cracks and the formation of discontinuous chips that are cutting characteristics in brittle materials. Location data was analyzed to judge the status of surface roughness after the numerical cutting process was analyzed. Numerical analysis was conducted to find optimal cutting conditions by investigating the surface roughnesses resulting from changes to various factors (cutting speed, cutting depth, rake angle). Finally, using the optimal cutting conditions found (high cutting speed, low cutting depth, and a rake angle close to 0°) was shown to contribute to improved surface roughness. |

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.
