Tooling plays important role in ensuring precision of cold forging part. In this study, a modular approach was proposed in the design of the tooling in the production of Autonomous Underwater Vehicle (AUV) propeller blade. Based on the conceptual design and optimization of the process sequence, the tooling was designed. As a result, the precision of the forged blade is still within the acceptable level.
