ABSTRACT

In recent years, sheet metal forming has gained great importance in the production process. To improve the quality of the manufactured products and reduce the production cost, incremental forming, particularly that adapted to small pieces, can be a good alternative. It is within this scope that the present study was carried out. This research work deals with the finite element simulation of the incremental forming process applied to achieve a trunk cone. It also examines the effects of the geometrical parameters of the tool and of the sheet on the forming force, stress distribution and thinning of the sheet. The obtained results show that the thinning of the sheet is more important in the case of the continuous tool path (about 0.2 mm), compared to that in the discontinuous one.

摘要

近年来，钣金成型在生产过程中变得越来越重要。为了提高制成品的质量和降低生产成本，渐进成型，特别是适用于小件的渐进成型是一个很好的选择。本研究正是在这个范围内进行的。本研究工作涉及用于实现主锥体的增量成形过程的有限元模拟。它还检查了工具和板材的几何参数对成形力、应力分布和板材减薄的影响。获得的结果表明，与不连续刀具路径相比，在连续刀具路径（约 0.2 毫米）的情况下，板材变薄更为重要。
