针对透平膨胀机整体叶轮叶片薄、扭曲大和叶片间隔小的特点,结合NX软件和五轴数控加工中心,实验验证了一种加工策略,从叶轮毛坯的成型到整体叶轮粗、精加工工艺参数的设置以及机床的应用都提出了有效的解决方法,这些技术已成功运用到多种整体叶轮的加工,并取得了预期效果。 Aiming at the characteristics of the turboexpander such as thinner blade, larger torsion and smaller blade spacing, a machining strategy was validated by NX software and five-axis CNC machining center. The process parameters from the forming of the impeller blank to the coarse and fine finishing of the whole impeller Setting and machine tool applications have put forward an effective solution, these technologies have been successfully applied to a variety of integral impeller processing, and achieved the desired results.
