| Popis: | 92 Machinability of Ti-6Al-4V Titanium Alloys Student：Yen-Chih Chiu Advisor：Dr. Neng-Hsin Chiu Department of Mechanical and Automation Engineering National Kaohsiung First University of Science and Technology Abstract Regarding the usable field of Ti-6Al-4V titanium alloys, it involved in a wild-ranging area which includes aerospace industry, nuclear industry, munition industry, and life industry especially in the aviation industry. Although this typical of material occupies the higher difficulty; for users, it forms an important issue about how to choose the tools and cuttint data. The air package; however, which required strict quality after processing as well. Consequently, we provided the basic quality management of tool and cuittint data through a set of references. Even more it’s in connection of the tool life and quality management after processing. According to the discussion of machinability, we utilized the energy of consuming change in all cuttint process which observed with the result of tool wear, then do a further evaluation for suitable cuttient tool and data. Besides we could find out through some relation in cuttint energy, surface roughness and hardness for tool life and surface quality of work piece. Moreover its could be reference in efficiently managing tool life and processing quality. The result is as the cuttint energy was enlarging, the consuming range generally widening as well. Initially, (In flank wear period), surface roughness appears the direct proportion by the raise of cuttint energy. It means the more cuttint energy, the less surface roughness. Another result presents the more energy entered the tool’s surface which was leading some change in hardness. In other words, as if when above largely change over, the more stresses concentration appeared. Therefore not only a distinct conception in choosing the tool and cuttint data but provided an excellent information to tool life and quality management by processing discussion. Key words: Ti-6Al-4V、machinability、specific cutting energy、surface quality |
