| Abstract | The manufacturing of molds and dies requires that complex hardened-steel surfaces be milled. The deep cavities in these parts are generally cut using high-speed machining technologies and long, slender tools. Consequently, the milling cutter has a tendency to vibrate, potentially damaging the surface of the workpiece and causing the cutting tool to chip or break. This study investigates tool life, cutting forces, and surface roughness in ball-end milling of a curved, convex surface of AISI D6 tool steel with a hardness of 62 HRC. The main goal was to find cutting conditions that provide good surface quality with long tool life. Two cutting strategies (upward and downward) with three lead angles (−16°, 0°, and 16°) were tested. Analysis of variance was used to understand the results better. Adhesion followed by chipping of the cutting edge was the main wear mechanism found. The results show a close relationship between radial components of the machining forces and surface roughness and tool life. The cutting conditions that provided the lowest radial force also generated the best surface finish and the longest tool life (an upward strategy with a lead angle of 0°). |

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.
