Mould profile soft compensation method for surface quality of outer covering part of vehicle body

The invention discloses a mold profile soft compensation method for the surface quality of an outer covering part of a vehicle body. The mold profile soft compensation method comprises basic data quantification before soft compensation, application of soft compensation medium-AB glue, application of a special tool for correcting a soft compensation surface, control means of a shape conforming process and the like. According to the method, the surface quality defect state of the vehicle body outer covering part and the male die A surface state of a vehicle body outer covering part die are determined by using precision measurement equipment to determine an experimental compensation position; comparing the vehicle body outer covering part surface quality defect range with the vehicle body outer covering part die male die A surface missing range, and determining an experiment compensation range; selecting a reasonable soft compensation medium to cover and solidify the soft compensation medium in a male die A surf
