This study focuses on developing a new toolpath strategy for manufacturing near-net shape corrugated structures using rectangular sheets whose two opposite edges are clamped based on the mechanics of Double-sided incremental forming (DSIF) process. The newly suggested strategy, Regional Plastic Incremental Bending (RPIB), is designed to capitalize on the effect of regional plastic bending in a way that a local geometric feature is incrementally formed without causing global elastic springback. The performance of the RPIB toolpath strategy is compared to the previously developed linear toolpath strategy that does not consider any anticipated springback errors in its design stage. It has been experimentally proven that the RPIB strategy results in significant improvements in the geometric accuracy of formed corrugated profiles.

本研究的重点是开发一种新的刀具路径策略，用于使用基于双面增量成型 (DSIF) 工艺的力学夹紧两个相对边缘的矩形板制造近净形波纹结构。新建议的策略，区域塑性增量弯曲 (RPIB)，旨在利用区域塑性弯曲的影响，以增量形成局部几何特征而不引起全局弹性回弹的方式。将 RPIB 刀具路径策略的性能与之前开发的线性刀具路径策略进行了比较，该策略在其设计阶段不考虑任何预期的回弹误差。实验证明，RPIB 策略可显着提高成型波纹轮廓的几何精度。
