Composite structure member profiling data generation method

Abstract

This invention provides a method for generating contouring data for composite structural components, comprising: determining N key feature points based on the composite component to be contoured; coarsely sampling points on the composite component based on the N key feature points to obtain coarsely sampled point data; dividing the original digital model into M sub-digital models based on the coarsely sampled point data; performing virtual fine sampling to obtain virtual fine sampling point data sets corresponding one-to-one with each sub-digital model; registering the coarsely sampled point data and the M virtual fine sampling point data sets; unifying the registered sampling point data to the equipment coordinate system, and then substituting it into a post-processing program to obtain the final fine sampling point data for composite contouring. This method combines the coarsely sampled point data obtained from sampling points on the composite component with the virtual fine sampling point data sets obtained from virtual fine sampling on the sub-digital models, reducing the time spent sampling points on the composite component during contouring and improving the efficiency of contouring data generation.
