以往的研究表明，特征检测和零件分割是有用的工具，以产生补偿刀具路径的单点渐进成形，从而提高制造零件的精度。然而，在大多数实际应用中，特征并不会自己出现。相反，它们与其他特征组合出现，并且相邻特征的存在影响感兴趣特征的行为。成形零件的最终形状取决于特征之间的相互作用。在这项研究中，已尝试生成一个完整的分类法的共同特点相关的增量形成的零件。然后利用该分类法生成特征交互矩阵，并将其分类为可行或不可行。从子集的可行功能的相互作用，一些情况下进行了分析，以说明的影响的相互作用的幅度和性质的不准确性，导致未补偿的部分。策略，使用这些功能之间的相互作用的知识，以提高制造的零件的精度，然后讨论与实验案例研究的帮助。
Previous studies have shown that feature detection and part segmentation are useful tools to generate compensated toolpaths for single point incremental forming leading to improvement in accuracy of manufactured parts. However, in most practical applications, features do not occur by themselves. Rather, they occur in combination with other features, and the presence of the neighbouring features influences the behaviour of the feature of interest. The final shape of the formed part depends on the interaction between the features. In this study, an attempt has been made to generate a complete taxonomy of common features relevant for incrementally formed parts. This taxonomy is then utilized to generate a matrix of feature interactions, and to classify them as feasible or not. From the subset of feasible feature interactions, a number of cases are analyzed to illustrate the effect of the interactions on the magnitude and nature of inaccuracies resulting in uncompensated parts. Strategies to use the knowledge of the interaction between these features to improve the accuracy of the manufactured parts are then discussed with the help of experimental case studies.
