The invention discloses a hole site
correction method applied to automatic drilling and riveting of curved surface products. The hole site
correction method comprises the following steps that S1, thetheoretical positions and the actual positions of four reference holes are compared to obtain vector errors of the four reference holes, and an error curved
surface function is constructed by combining the vector errors and a normal fitting bilinear
hybrid Coons error curved surface; S2, the fifth reference hole is introduced into a
hole making area, and the error which should be compensated by the reference hole is obtained through substitution; S3, a multi-objective optimization
genetic model is established by combining the actual vector errors of the reference hole, and the optimal value ofthe tangent vector model length of the four reference holes is calculated within a certain range, so that the error curved
surface function is determined; and S4, the corresponding value is calculated by utilizing the theoretical coordinates of the hole to be machined, then the hole site error of the hole to be machined can be calculated, and finally the error is compensated to the theoretical coordinates to obtain new theoretical coordinates, namely the hole site correction process is completed. The hole site
correction method has the advantages of being good in correction effect, wide in application range and capable of meeting the
hole making position precision requirement.
