本文介绍了基于机器人的渐进板料成形技术的新进展。机器人成形是一种无模具的板材成形工艺，可确保具有成本效益的原型零件和小批量制造。提出了一种提高机器人成形零件精度的方法。它是由德国联邦教育和研究部资助的一个名为Roboform的合作项目开发的。该项目致力于工业应用系统设计的开发。标准组件的使用允许模块化和可扩展的设置。由传感器和编程系统组成的伺服回路是此设计的基础，应通过测量成形零件与其目标几何形状之间的偏差来保证更高的零件精度。偏差被用来得出修正后的刀具轨迹。通过对刀具路径上的每个点进行调整向量来执行校正。文中给出了该策略的理论依据和初步结果。
This paper describes new developments in incremental, robot-based sheet metal forming (Roboforming). Roboforming is a dieless sheet metal forming process which ensures cost-effective manufacturing of prototype parts and small batches. An approach for increasing the part accuracy in Roboforming is presented. It is developed in a cooperative project funded by the German Federal Ministry of Education and Research called Roboforming. The project concentrates on the development of an industrial applicable system design. The use of standard components allows a modular and scalable set-up. A servo loop, consisting of sensors and a programming system, represents the basis of this design and shall guarantee higher part accuracies by measuring the deviations between a formed part and its target geometry. The deviations are used to derive corrected tool paths. The correction is performed by an adjustment vector for every point on the tool path. The theory for this strategy and first results are presented in this paper.
