由于渐进成形是一种较新的板料成形工艺，目前文献中用于研究渐进成形机理和提高渐进成形性能的解析和有限元预测模型非常有限。因此，大多数研究涉及许多试错迭代来优化加工条件，以利用高工艺灵活性和材料成形性。然而，减少反复试验的努力对于使过程在财务上可行是至关重要的。因此，有限元模型的开发和实验验证，以预测在渐进微成形过程中涉及的成形力。使用不同的质量比例因子和元素类型来优化和开发模型，以便在尽可能少的计算时间内进行准确的预测。
As incremental forming is a relatively new sheet metal forming process, very limited analytical and finite element prediction models are available in literature to study the process mechanics and improve its performance. Thus, most studies involve many trial-and-error iterations to optimize the processing conditions in order to take advantage of high process flexibility and material formability. However, reducing efforts of trial-and-error iterations is of utmost importance to make a process financially viable. Therefore, an FE model is developed and experimentally validated to predict the forming forces involved in incremental micro-forming process. Different mass scaling factors and element-types are used to optimize and develop the model for accurate prediction in the least possible computation time.
