The influences of temperature and surface roughness on the forming of the AA3003-H111 aluminium alloy sheet material have been investigated by using the finite element method. For this purpose, material cards have been firstly created based on the sheet material behaviour at different deformation temperatures. As a result of the forming analyses performed at different temperature values and surface roughness values, it has been determined that the increase in the surface roughness reduces the amount of thinning while it increases the amount of forming force and the springback. It has also been determined that there is a slight increase in the amount of thinning, while the temperature rise reduces the amount of forming force and the springback. In addition, the influence levels of temperature and surface roughness have been determined by statistical analyses.
