Abstract

The goal of this research is to design the mould for investment casting and investigate how the CATIA V5 software simulates the CAM process of a mould propeller blade by using the machining strategies such as multi-axis sweeping and multi-axis isoparametric by using the same parameter. Then, using a 5-axis milling machine, complete the fabrication. After that, investigate the impact of machining strategies on the surface roughness.The previous method of creating the propeller blade used machining, and the blade had some issues, such as the surface roughness not being smooth and insufficient dimensions. The previous method, which used a mold to create the pattern of the propulsion blade using wax before the investment casting process, was abandoned for this project.The type of material used for the mould is aluminium.
