Abstract


Clad materials are increasingly used in the automotive and aerospace industries due to the significant advantages they offer. The incremental forming process of lightweight materials is gaining more interest because it allows the production of relatively complex parts at lower costs, eliminating the need for complex and expensive molds. Understanding the phenomenon of thickness reduction is essential, as it directly influences the mechanical strength of the manufactured parts. In this work, the thickness reduction of the EN AW-3003 aluminum alloy clad with EN AW-4343 was studied following the incremental forming process. Two methods were used for the thickness reduction analysis. The first method involved non-contact optical measurement using the ARAMIS optical measurement system. The second method focused on analyzing the clad layer using optical microscopy. The obtained results enhance the understanding of the behavior of clad materials during incremental forming and may serve as a foundation for optimizing the manufacturing process.
