摘要 提出一种关于单点渐进成形(SPIF)部件的特征检测的新型算法。基于自建的关于SPIF的CAPP专家系统,通过对几何形状、曲率、位置、方位、加工参数的综合分析,可以检测33种不同的特征可以检测。为了加快检测过程,首先使用多级边缘分割算法创建一个边缘特征的框架。随后在这个框架中,区域生长算法被用来检测剩余的特征。这个检测方法已经成功地被不同的实验所验证。采用一个双曲面半球的实验案例描述通过对检测的特征进行补偿,从而生成最优的刀具路径。结果显示,优化的刀具路径对于成形部件的精度有很大的提高。 提出一种关于单点渐进成形(SPIF)部件的特征检测的新型算法。基于自建的关于SPIF的CAPP专家系统,通过对几何形状、曲率、位置、方位、加工参数的综合分析,可以检测33种不同的特征可以检测。为了加快检测过程,首先使用多级边缘分割算法创建一个边缘特征的框架。随后在这个框架中,区域生长算法被用来检测剩余的特征。这个检测方法已经成功地被不同的实验所验证。采用一个双曲面半球的实验案例描述通过对检测的特征进行补偿,从而生成最优的刀具路径。结果显示,优化的刀具路径对于成形部件的精度有很大的提高。
