AI Technical Summary
Existing technologies cannot effectively solve the problems of inconsistent model space representation, difficulty in determining the laser action area, and lack of unified benchmarks in multi-axis laser processing, leading to processing errors and damage.
A hierarchical bounding box-based approach is adopted to establish a unified spatial reference benchmark by constructing overall and sub-bounding boxes, enabling efficient determination of the laser action area and generation of multi-axis machining paths. This includes model topology analysis, spatial normalization, hierarchical bounding box construction, laser energy distribution modeling, and path optimization.
It achieves uniformity and geometric unambiguity in model space representation during multi-axis laser processing, improves spatial query efficiency and the degree of automation in path generation, ensures that laser energy is effectively applied to the target area, and reduces processing errors and damage risks.
