Beschreibung
Zusammenfassung:	The invention discloses a repairing method for a turbine blade mold. The repairing method comprises the following steps that an actual three-dimensional model and a theoretical three-dimensional model of a turbine blade are obtained; setting a positioning point on the turbine blade, obtaining a theoretical coordinate value of the positioning point according to the theoretical three-dimensional model, fitting the actual three-dimensional model and the theoretical three-dimensional model of the turbine blade to obtain an actual coordinate value of the positioning point, and obtaining a deviation value of the positioning point; setting a plurality of feature detection points on the turbine blade, and adjusting the theoretical coordinate values of the positioning points by using the deviation values of the positioning points to obtain the coordinate values of the adjusted positioning points; performing six-point positioning fitting on the actual three-dimensional model and the theoretical three-dimensional model
