| Abstract | In this work, the ultimate compression force that enables the plastic removal of brittle materials in diamond turning is initially modeled according to the theory of rigid-plastic mechanics. And subsequently, an independent oscillator model is reconstructed to calculate the microfriction force that appears at contact interface. As expected, a predictive model considering the ultimate compression force and microfriction force is finally established to calculate the critical undeformed chip thickness of brittle materials in diamond turning, in which a crack-free surface of brittle materials can be achieved as quickly as possible in a brittle-ductile coupled cutting mode. Based on the theoretical predictions and experimental observations, the “size effect” of the critical undeformed chip thickness is discovered, i.e., that the ratio of the critical undeformed chip thickness to tool cutting edge radius increases with the decrement of tool cutting edge radius. Such interesting variation law is attributed to the strengthening of the effect of the microfriction and concentration of the compressive stress under a small enough cutting edge radius, which produces more favorable conditions for the brittle-ductile coupled removal of brittle materials. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
