| This passage introduces the properties of titanium alloy. To analyze the causes why titanium alloys are so difficult to machining. To introduce the current stage of high speed machining on titanium alloys at home and abroad. It makes a clear picture that there is a large gap of titanium machining between home and abroad.Titanium alloy is a kind of new and reliable performance material which has been widely used in Aerospace industry. But it is also a kind of material that is very difficult to cut. The material properties limited its machining efficiency and quality. Also the serious tool wear, big distortion makes us difficult to get a good surface finish performance. Now our country is developing large airplane project, and the titanium machining will be used more and more frequently in related aerospace company so that this topic is very useful in production.Focus on the manufacturing process of a complicated titanium part, do research on below areas:1)According to the drawing and specification, prepare the manufacturing process.2)Optimize the cutting path and select the most reliable cutters. Improve the efficiency and quality.3)Analyze the relationship between helical angle and surface finish. Conclude the most suitable helical angle for titanium alloy profile machining.4)Analyze the root cause of tool wear. Conclude the improvement method according to different kinds of tool wear.This project is started with preparing the manufacturing process of a complicated titanium part with the advanced manufacturing process abroad. To design and optimize the process, to use the advanced cutters and to achieve a typical and effective machining process for titanium alloy to obtain a good economic benefits. |
