Improved Surface Quality with TiN-Coated Tool

The emergence of incremental sheet forming has led to the development of innovative manufacturing techniques that possess great adaptability and hold the potential to provide substantial economic advantages in the realms of advanced technologies and low-volume production. In this study, specialized analyses are conducted to determine the structure and morphology of the surfaces produced after single-point incremental sheet forming (SPISF). The material subjected to SPISF is Al 3003. For the material forming, two types of tools, one uncoated and one coated with titanium nitride (TiN), are used. It is observed that the TiN-coated tool yields the most favorable roughness outcomes and also reduces the values of the forming components. According to the scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS) analysis, the deposition of the TiN on the tool is uniform, thus the results relate to the surface roughness and not only justified. © 2024 Wiley-VCH GmbH.
