Prototyping with experimental methods can be used to find out the data from the analysis that has been carried out. However, if many iterations are carried out, it can certainly require a lot of time and money. For example, in making prototypes/products, the variations are multiplied by the data amount for the validity and reliability stages. Therefore, this study tried to present the FEA simulation method to determine the efficiency of failure prediction and the sheared edge characteristics. Hereafter, experiments using the same parameters to determine the deviation of the resulting data were conducted to validate it. Several indicators that affect the implant plate in punching operations are the sheared edge surface quality. This research used an experimental punching method on the Ti-6Al-4V material with 0.6 mm thickness and chamfered, fillet, and flat tool shape variations. The sheared edge characteristics were observed using digital microscope. The simulation results showed that the flat tool tip produced a large shear zone of 0.489 or 81.5% of the plate thickness, while the value of 0.42 mm or 70% was obtained from the experimental results. The flat tool also showed a minimal burr value compared to the chamfered or fillet tools, in which larger chamfered or fillet created rougher sheared edge characteristics. © 2025 American Institute of Physics Inc..
