Emre EROL Mehmet Erdi KORKMAZ Mustafa GÜNAY
AbstractMachining parameters for manufacturing methods can be optimized based on the finite element method using numerical simulation software. In this study, the simulation of the hot rolling process was performed for plain round bar producing. Rolling simulations were done in DEFORM-3D software and the hot rolling process was analyzed with three different rolling temperatures and rotation speed of rolls. In the results of numerical analysis, diameter and circularity tolerances have been measured for the product. The outputs of the finite element simulation were evaluated to determine the effects of rolling parameters on size quality of round bar product. The analysis of variance (ANOVA) with %95 confidence level was performed in order to determine the effect level of rolling parameters. It was determined that the rounded product geometry is out of diameter and circularity tolerances by increasing the rolling temperature and the rotational speed.
