Pengaruh Parameter Proses Incremental Backward Hole-Flanging terhadap Ketebalan Kerah pada Alumunium 1050A

Abstract

Conventional hole-flanging process in a small batch is sometimes costly or almost impossible due to the variety of the product profile. Recent studies showed that modern manufacturing was developed to overcome the limitation of the conventional hole-flanging process. Incremental backward hole-flanging (IBHF) was one of the strategies that developed to overcome this particular limitation. The main objective of this research was to investigate the influence of IBHF process parameters toward collar thickness of the product. It enables to measure the impact and behavior of each process parameters, i.e., forming speed, axial and radial forming step size toward the particular response parameter. The result showed that axial and radial forming step size was the main influence and the forming speed has a slight effect towards collar thickness. The behavior of each parameter was increased forming speed and radial forming step size would decrease collar thickness, whereas increased axial forming step size would increase collar thickness.
