“…Reddy et al [10] used the Taguchi fractional factorial design and analysis of variance to find the optimum process parameters and their influence on the thickness variation at different regions of the blank material for AA6111 aluminum alloy. Another similar example was reported by Raju [11], where he used Taguchi's signal-to-noise ratio and observed that the die shoulder radius has a significant influence on the thickness distribution of the deep-drawn cup of AA6061 sheet followed by the blank holder force and punch nose radius.…”

Product quality is one of the important aspects in deep drawing practice and the variation in process temperature was claimed to improve the quality. Therefore, in this research, the effect of the heating temperature on the drawability of a circular metal cup has been investigated. Firstly, circular metal cups of aluminium, mild steel and stainless steel were drawn from the blank diameters of 60 mm, 65 mm, and 70 mm. The experiment was conducted at room temperature followed by at 100 °C, 150 °C and 200 °C. The Taguchi method was selected as the design of experiment approach, and L9 (34) array design methodology was adopted in this experimental research. The drawability was measured based on the punching force needed to deform the sheet metal blanks. The deep drawing process was conducted at room, and elevated temperature conditions and the response factor was analysed and compared through the analysis of variance (ANOVA) statistical approach. The results obtained from ANOVA indicate that the blank material has a significant influence on the deep drawing process followed by the blank size, heating temperature and heating technique. The optimal parameter combinations are blank diameter of 60 mm, heating temperature of 200 °C and the die and punch heating technique. Out of the three materials investigated, aluminium has a better drawability compared to mild steel and stainless steel.

“…Sheet metal forming processes are affected by many different parameters such as surface quality (lubrication conditions), temperature, blank holder pressure and forming speed [3][4]. Aluminium alloys exhibit the properties of high ductility and formability at temperatures below the recrystallization temperature although they have low formability at room temperature [1][2].…”

SummaryThe 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.
