摘要
随着现代飞机制造技术的不断提高,零件的复杂程度在逐渐加大,钛合金的应用也愈加广泛,这就对钛合金零件加工工艺提出了更高的要求。对于复杂钛合金零件数字化加工所用到的工程数模有的不能完全满足加工需要,为此,需要根据零件形状和材料特性等相关工艺重新构建区别于工程数模的工艺数模,进而更好地完成钛合金零件的加工制造。这里主要介绍了工艺数模在ARJ21飞机焊接类钛合金零件加工制造过程中的具体应用实例。
With the development of modern aircraft manufacturing technology continuing to improve,the complexity of parts in gradually increasing,the application of titanium alloys are also becoming more and more widespread,and the machining process of titanium alloy has put forward higher requirements.For the complex titanium alloy parts of digital processing all engineering model and some can not fully meet the processing needs,therefore,it needs according to the shape of parts and material properties and other related technology to reconstruct the process model from the engineering model,manufacture and complete better titanium alloy parts.It mainly introduces the specific application process model of welding titanium alloy parts processing in ARJ21 in airplane manufacturing process.
