Application of CAD/CAM/CAE in modelling of Die for Hot Forging of Stainless Steel Valve

— The study aims to present and analyze the correlation between tools such as the durability of the tool, and the quality of the output product of the valve when stamping the 3-sided valve, the expected result of each case approved by the simulation. The results of the analysis and simulation process will give the advantages and disadvantages of each case, from which to conclude and choose methods of optimal and efficient machining for practical application. The research was carried out with the help of QForm software, that allows finding the optimal interference value that provides a state of compressive stress in complex but fragile particles under actual stamping loads. It can predict defects in the actual hot forging process based on simulation, thereby minimizing defects by many different options such as changing the stopping distance of the pestle, velocity, and embryo.
