Effect of Die Modification to Geometrical Defect of Cold Forged AUV Propeller Blade

Abstract:

Accuracy and characteristics of the die and punch plays a significant role in the forming process. The perfectness of the die and punch will not guarantee that the part form as desired. Therefore, the die or punch needs to be modified. In practice, the modifications will be carried by trial and error based on the experience of the fabricator and the amount or removed section is unknown. In this study, the contribution of die modification to the geometric defect will be quantified by comparing the blade profile obtained from the nominal geometry of the blade and the profile constructed by commercial optical method namely Alicona system. For validation, Coordinate Measurement Machine was used
