| Abstract | Ultrasonic cutting of bone offers advantages compared with orthopaedic devices that rely on a reciprocating action, including the elimination of swarf, improved cut quality and precision, and reduced reaction forces. The technology has become accepted as an alternative cutting procedure for use in surgical operations on soft tissue. Recent studies conducted on bovine bone and a bone substitute material have shown that ultrasonic cutting results in a precise and fast operation using relatively low forces. Previous work by the authors highlighted the significance of frictional heating during ultrasonic cutting, a phenomenon that can lead to material degradation and excessive burning of the cut surface. The work presented a method of reducing cutting temperature by controlling ultrasonic cutting parameters and also presented a method of further reducing cutting temperature by incorporating blade geometry modifications that reduce friction between the blade and the specimen. Such studies have been concerned with uni-axial cutting blade orientations, known as guillotine cutting, and opportunities exist to enhance orthopaedic ultrasonic cutting by developing blades that can operate in more than one cutting direction. This paper investigates the relationship between cutting parameters (such as cutting speed, applied load and blade tip vibration velocity) and temperature at locations around the cut site for a synthetic bone material during guillotine and slicing mode cutting |

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.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
