In this article, particularities of an incremental forming application as additional technology in multi-layer construction element production are presented. Special attention is dedicated to the forming principles, the forming influences on the mechanical properties of the multi layer element and the corrosion of the locally deformed coloured metal plate. It was discovered that the statics of the multi-layer element improves if appropriate shape parameters in connection with process parameters are applied, where the painted layer remains undamaged, even after demanding anticorrosion tests.

Before starting the production forming processes require real experiments in order to accurately define forming limits. For this reason and due to the fact that incremental forming technology requires relatively long production time, autonomous on-line system for fracture identification is developed. The system represents a versatile tool for the identification of location and time of the fracture occurrence without human influences and their presence. The system is based on the investigation of the forming forces, responsive to very small variations, appearing during the forming process.

In this paper, a method of predicting the load capacity behavior of individual construction elements performed by incremental forming as an additional technology in multi-layer construction element production is presented. Special attention is dedicated to the definition of finite element model of a standardized four-point bending test and its correlation to real experimental results.

The paper presents digital validation of innovative technology called single point incremental sheet metal forming of various sheet metal shapes made from steel DC05. Special attention is dedicated to surface stretches and sheet metal thinning prediction. In order to confirm the quality of obtained results from digital environment and their usability in industrial practice the comparison with real experimental results is made and discussed. The results show the nummerically obtained results fit well with experimental one, that means that numerical model could be applied in real production.

The paper presents a modern manufacturing concept called the “backward incremental hole-flanging process”. It enables drawing necks on the final products that can be very complex or even closed with minimal expense. Special attention is dedicated to researching the most influential process parameters affecting the neck height and the thinning of the neck using empirical modelling. Results show that forming tool diameter, and horizontal and vertical step sizes have the greatest influence on the forming results.
