摘要:
针对辊锻模具型槽具有的工艺特点 ,在分析各扫成曲面算法的基础上 ,采用了 Siltanen提出的投影法矢法计算局部坐标系 ,提出并实现了基于辊锻模具型槽工艺特点的扫成曲面算法。实例表明该算法可行 ,效果令人满意
Based on the technics feature of roll forging die cavity, the Projection Normal Method presented by Siltanen was used to calculate Frenet frame, and the algorithm of swept surface was researched and implemented in this paper.
