Method for determining repair mode of part

The invention provides a method for determining a part repair mode, and belongs to the field of machine manufacturing. The determination method comprises the steps that according to the defect of a part, the repair feature of the defect after repair machining is determined, and the repair feature is used for indicating the shape and size of the defect after repair machining; establishing a three-dimensional model of the repaired part according to the repair features and the theoretical size of the part; and when the three-dimensional model meets the design requirement, repairing the part according to the size corresponding to the repairing feature. The repair qualification rate of the parts can be improved. 本公开提供了一种零件返修方式的确定方法，属于机械制造领域。所述确定方法包括根据零件的缺陷，确定所述缺陷在返修加工后的修复特征，所述修复特征用于指示所述缺陷处在返修加工后的形貌和尺寸；根据所述修复特征以及所述零件的理论尺寸，建立修复后所述零件的三维模型；当所述三维模型满足设计要求时，根据所述修复特征对应的尺寸，对所述零件进行返修。本公开可以提高零件的返修合格率。
