Abstract

In die designing, one of the most crucial decisions is selecting the appropriate die process required to produce panels. The challenge for die designer is to comprehend the behaviour of the panel material in relation to the die processes. If the die process is not correctly determined before die fabrication, severe panel spring back may occur, which can become difficult and require additional time and effort to rectify. This paper presents research aimed at understanding the behaviour of different types of bending process combinations concerning the spring back occurrence during the stamping process of an L-shaped design intent panel. Using simulation and experiment, three types of materials with different tensile properties of 270 MPa, 440 MPa and 590 MPa, but the same thickness of 1.8 mm, were selected. The results were compared, analysed and optimized by using Response Surface Methodology (RSM) method. The results demonstrate that one-process bending with full bending (compress type) approach, is the most suitable for the three materials type L-shaped panel. The study provides guidelines for die design engineers, industrial practitioners and researchers to decide on the best approach for die process decisions, when dealing with specific panels properties, shape and thickness.

Dr. Ali Sophian C.Eng, obtained his BEng and Ph.D from the University of Huddersfield in UK. His PhD project was funded by the University of Huddersfield and Cambridge-based TWI Ltd. He also received the Overseas Research Scheme grant from the Universities, UK during his PhD.
Following the completion of his Ph.D, he was appointed as a Research Fellow at the same university on a collaborative project with Warwick University. The project was on electromagnetic NDT sensors and funded by the EPSRC. After the end of the project, he joined the mechatronics group, under the Advanced Engineering Department, at Cummins Turbo Technologies (CTT) in England. While he was a senior mechatronics engineer, he became a chartered engineer and co-authored a world patent on variable turbo geometry.
He also successfully co-supervised a Ph.D student at the University of Manchester, where he was also a member of its Industrial Advisory Group (IAG), in an automotive actuator project. Having spent eight years in the industry, he moved back to academia by joining the Mechatronic Department of Kulliyyah of Engineering at IIUM. Dr. Ali Sophian has written more than 20 scientific papers in Electromagnetic NDT and actuator modelling. He holds a green belt in Design for Six Sigma, a product or process development methodology widely-used in the industry, especially automotive.
