摘　　要：文章介绍了一种基于加工末级枞树型叶根长叶片采用的先汽道后叶根的工艺方法通过叶片变形数据求解个性化叶根加工方案,取消传统机械校形,实施多工序协同改善叶片型线位置度以满足设计标准的综合误差控制加工方法。该方法在某1000 MW等级超超临界二次再热机组末级1400 mm长度等级的钛合金叶片试制时进行验证,结果表明:该方法可取代传统机械校形并保证型线位置度符合设计标准要求。This paper introduces a comprehensive error control processing method based on the blade method to solve the personalized root machining based on the data of blade deformation,which cancels the traditional mechanical calibration and implements multi-process collaboration to improve the blade profile position to meet the design standard.The method is validated in the trial production ofa 1400 mm length grade titanium alloy blade of one 1000 MW ultra-supercritical double-reheat steam turbine.The results show that the method can replace the traditional mechanical calibration and ensure the position of the profile meeting the design standards.
