Abstract

The use of polymeric composite materials has increased considerably over the last decade leading to an increase in the number of technical research papers focusing on relevant aspects concerning the machin ability of such materials. The principal aim of this work is to screen through the literature on machining of composite materials, more specifically on drilling of glass/carbon fibre reinforced epoxy composites. Aspects such as tool materials and geometry, machining parameters and their influence on the tool wear are investigated using wear mechanism mapping. Owing to this fact, many researchers have worked on metals,conducting series of experiments on wear and wear rate, and developed the wear mechanism map for different combinations of tool and work materials. But no significant work has been recorded so far on the wear mapping and tool wear characteristics of drilling on composite materials using wear mechanism mapping. Hence, the observations and outcomes of this research would significantly contribute to the wear mechanism of drill bit while machining composite materials. Moreover, composite materials makes them one of the important materials in aerospace engineering, automobile engineering, medical applications,structural application etc. Hence, the study of tool wear and tool wear mechanism is an important area. Hence, this paper makes an attempt to investigate and review the different wear mechanisms of drill tool during drilling on polymer matrix composites and to arrive at optimum process parameters through wear mechanism mapping. The observations and outcomes of this research paper would significantly contribute to the tool wear mechanism of drill bit while machining composite materials and the findings of this study can lead to the identification of improved operational parameters
