Generally, the crash box on automobile vehicles is a thin-walled structure with a square cross-section. The majority of research was carried out for a long time to find the optimum crashworthiness indicator. In this study, numerical simulations and e
Roughing processes create workpieces that are similar to actual forms in short periods of time. However, the current method, which involves either three-axis or five-axis machines, is limited in regards to workpiece feed accessibility. Often, signifi
