The invention discloses a
forge piece adjusting method based on three-dimensional scanning auxiliary positioning. The method comprises the following steps: S1, model acquisition: determining at least three feature points on a part blank, and establishing a
standard model and a blank model; s2,
data acquisition: superposing and matching the
standard model and the blank model, and measuring standard three-dimensional coordinates of the feature points by using a coordinate
system of the
standard model; placing the part blank on a
machine tool, and measuring
machine tool coordinates of the feature points; calculating a standard difference value and a
machine tool difference value on the axis corresponding to any two feature points; and S3, calibration determination: performing calibration to enable the standard difference value to be close to or equal to the
machine tool difference value. According to the invention, through assistance of three-dimensional scanning calculation, the calibration control target is simplified, the
calibration result is clearer and predictable, the calibration difficulty of the forged piece is greatly reduced, the production period is shortened, the production cost is reduced, and the shortage risk caused by
machining calibration is effectively controlled.
