| Abstract | Small-diameter end-mill is a key element for micro-machining technique. It is a new attempt to manufacture a small-diameter tool with polycrystalline diamond (PCD), which is also a hot issue in the research area of micro-manufacturing. PCD end-mills with small-diameter were fabricated and utilized in micro-milling. With a contact simulation model, the stress distribution and potential crack propagation of the PCD tool was revealed via 2D finite element (FE) analysis of 2Al2 aluminum alloy acting on the tool surface. Thereafter, a series of machining experiments on 2A12 micro-part were carried out with the PCD small-diameter end-mill. The wear characteristics of the rake face and flank face were analyzed, and the wear mechanisms of small-diameter end-mills were carefully investigated by using scanning electron microscope (SEM) and energy dispersive X-ray (EDX) spectroscopy. Three typical breakage morphologies of PCD end-mills were demonstrated while machining the aluminum alloy workpiece, i.e., the breakage of the tool tip, the edge chipping, and the peeling off of PCD layer. The consequent experiment results showed that abrasive wear, adhesive wear, and oxidative wear were the predominant characteristics in the damage region of PCD small-diameter end-mill. The effect mechanisms of various wear characteristics were also analyzed and revealed in detail. The experimental results were discussed according to the simulation results and effects on failure behavior of the PCD tool. The research can provide a better understanding for the wear and breakage behaviors of the downsized PCD tool in machining aluminum alloy and underpin the development of micro-milling process with diamond tool. |

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.
