| 英文摘要: |
| ISCO (Intelligentized shape-conforming and opening) system was developed based on the CATIA platform to design shape-conforming and opening intelligently. This system could enclose curve sets intelligently through appropriate human-computer interactive operations as well as bridging, trimming and offset operations. To make the body fit for manufacturing, the function of curve smoothing optimization was offered in this system. Publish technology and parametric driven function provided by CATIA were used to realize the intelligent and parameterized update of shape-conforming and opening system for automobile panel die. This system achieved rapid design of shape-conforming and opening, and could be updated in real time at assemble level and part level. This system specified the standards when designing shape-conforming and opening systems and effectively improved the efficiency of die structure design. |
