Dissertation note: Project paper (Bachelor of Mechanical Engineering with Manufacturing) -- Universiti Malaysia Pahang - 2008 Abstract: Titanium and its alloys are widely used in various industries mainly aviation. However, it is considered as difficult-to-machine material due to its unusual high cutting temperature, which leads to many research works on machinability of this material. In the current work, tool wear of titanium aluminum nitride (TiAlN) coating insert in turning of Ti-6Al-4V have been experimentally studied under conventional wet and cryogenic cooling. After each machining time, the tool edge was observed under microscope. Wear images were captured and analyzed by the image analyzer to identify different forms of wear occurrence. Experimental results have shown that for high cutting speed cutting, insert worn rapidly and also chipped in the case of wet turning, whereas no appreciable wear was found in cryogenic turning. In summary, this project achieved the objectives whereby the cryogenic coolant give positive influence on the tool wear.
