Abstract
In this thesis, the incremental sheet metal forming process have been assessed and controlled for the optimal possible performance of the process. In particular, this study involves experimental and Finite Element investigation the effect of sheet thickness and surface roughness in single point incremental forming (SPIF) of Aluminum 6061. Initially, a set of forming tests were carried out under a range of forming parameters. The data obtained from these experiments helped in analyzing and understanding the sheet thinning phenomena and generated surface roughness during the forming process. Furthermore, these results showed the relationship between the incremental depth and sheet thickness at different feed rates and different rotation speeds for the configuration head. However, the relationship between the surface roughness and incremental depth was carried out at different feed rates and different rotation speeds for the configuration head. In addition to, the effect of the different rotation speeds for the configuration head on the sheet thinning at various levels was obtained. Furthermore, Finite Element Analysis (FEA) was implemented to simulate the SPIF process for Aluminum 6061under restricted process parameters. The simulation outcomes were validated by experimental results, where a good agreement between both results was found. This agreement has confirmed the initial hypothesis that FEM is a reliable means to simulate the forming process. Finally, the study was accomplished by conducting an optimization study of the process to identify the optimal forming conditions.
