  Quality control in the manufacturing industry has improved with the use of
artificial intelligence (AI). However, the manual inspection of trimming die
designs, which is time-consuming and prone to errors, is still done by
engineers. This study introduces an automatic design inspection system for
automobile trimming dies by integrating AI modules and computer-aided design
(CAD) software. The AI modules replace engineers' judgment, and the CAD
software carries out operations requested by the AI modules. The inspection
process involves a zigzag interaction between the AI modules and CAD software,
enabling one-click operation without expert intervention. The AI modules are
CAD-independent and data-efficient, making them adaptable to other CAD
software. They achieve high performance even with limited training data, with
an average length measurement error of only 2.4%. The inspection time is
reduced to approximately one-fifth of the time required for manual inspection
by experts.
