| Abstract | In machining, many output parameters are used to diagnose machinability. Parameters such as tool wear, tool life, cutting temperature, machining force components, power consumption, surface integrity, and chip thickness ratio are regularly employed. The aim of this work is to investigate the behavior of the machining force (Fu), chip thickness ratio (CTR), and chip disposal when turning ductile (1350-O grade) and of high strength (7075-T6 grade) aluminum alloys at various cutting conditions (cutting speed: Vc, feed rate: f, and depth of cut: doc). A central composite design (CCD) of experiments was used that generated second-order models of the parameters: [Fu (Vc, doc, f); CTR (Vc, doc, f)]. Surface response methods and level curves were used for studying the effects of the cutting conditions on the output parameters: Fu and CTR. The cutting conditions (Vc, doc, and f) that simultaneously minimize the machining force (Fu) and the CTR were determined with the help of the genetic algorithm method (GAM). The results showed that all the input parameters acting both individually or in combination with each other had significant effect on the responses. Moreover, the machining force (Fu) followed a similar trend as the CTR when the input parameters were varied; i.e., they decreased when the cutting speed increases and increased at higher feed rate and depth of cut. |

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.
