[en] Machining of hard material is always a big challenge for industrial application point of view. However, machining of this hard material is possible by taking appropriate machining parameters. Titanium Ti-6Al-4, Inconel 718 and Tool Steel are also very hard material. In this study, comparative machining study of these materials was discussed. From the exhaust literature of these materials, it was observed that machining of all these three types of hard material is possible with good surface finish by taking appropriate machining parameters.

[en] Bagasse is a waste product which was produced from the sugar industry. These wastes produce lots of environment pollution in development. Effective utilization of these wastes can reduce lots of environment pollution. In this study, a literature review is carried out to observe the bagasse as reinforcement in the development of composite. From the literature, it was notified that bagasse can be used in the development of composite. (paper)
