ABSTRACT Prototype parts can be produced rapidly and at low cost using the incremental forming method. The most important problem with this method is that it causes undesirable variations in wall thickness. Various methods have been developed to improve the wall thickness distribution of the part resulting from forming. One of these techniques, the rolling blank holder (TPIF-RL) method, was used in this study to form 1 mm-thick HC380LA sheet. The Taguchi experimental design was used to determine optimum levels of each of the parameters (forming force, surface roughness and wall thickness) separately via signal/noise analysis. Gray Relational Analysis was then performed to determine the parameters that optimize surface roughness and wall thickness together. In the study, it was determined that the use of low pressing force increases the wall thickness. As a result, a 6% increase in wall thickness was achieved by using the optimum parameters.

通过 TPIF-RL 渐进成形法研究 HC380LA 材料的成形性

摘要 使用渐进成型方法可以快速、低成本地生产原型零件。这种方法最重要的问题是它会导致壁厚发生不希望的变化。已经开发了多种方法来改善由成形产生的部件的壁厚分布。本研究中使用了其中一种技术，即滚动压边条 (TPIF-RL) 方法来形成 1 毫米厚的 HC380LA 板材。田口实验设计用于通过信号/噪声分析分别确定每个参数（成型力、表面粗糙度和壁厚）的最佳水平。然后进行灰色关联分析以确定同时优化表面粗糙度和壁厚的参数。在研究中，确定使用低压力会增加壁厚。结果，通过使用最佳参数，壁厚增加了 6%。
