| Abstract | The hardened 18 % nickel maraging steels find potential application as an engine component for heavy vehicles and as armour metal in defence. The task lies in obtaining a good surface finish and minimal tool wear in hard machining of this high-strength material in a solution annealed and aged condition. The present work reports the optimal machining condition to obtain a good surface finish and lesser width of flank wear land during hard turning of maraging steel. The cutting speed, feed rate, and depth of cut are identified as the dominant parameters influencing the process responses. The working ranges of these machining parameters are set through the design of experiments, and an L$_{27}$ orthogonal array is used for conducting the machining trials in a CNC lathe using cubic boron nitride (CBN) cutting inserts. The surface roughness is measured using a surface profilometer, while the width of flank wear land is found out using a video measuring system. The grey-based response surface methodology is used for analysis. A lower value of surface roughness (0.434 µm Ra) and lesser flank wear (0.0234 VB$_{max}$, mm) is obtained at optimal machining condition (cutting speed 174.28 m/min, feed rate 0.01 mm/rev, and depth of cut 0.3549 mm). Atomic force microscopy (AFM) images and P-profile graphs of machined surface are also examined. Furthermore, the temperature distribution is also simulated for the optimal machining condition using the DEFORM 3D software. |

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.
