Design and Manufacturing of Marine Propeller Srirama

The present work is aimed at the fabrication of propeller blade using Aluminium-24345 material. It is high corrosive resistant, light in weight and easy to maintain. A propeller has a complex geometry and requires high end modelling in its software. The solid model of propeller blade is developed in CATIA V5 R20. By using this model, propeller was manufactured using CNC machine. CNC machining is one of the rapid manufacturing processes for producing metal parts. In this approach, the model is used to generate CNC code with the help of MASTERCAM MILL X6 software and the obtained code is uploaded to CNC machine using Post processor. CNC fabrication technology is unique in that fully dense metal components with properties which are similar to that material can be fabricated. The CNC machining process has the potential to fabricate complex internal features not possible using existing manufacturing processes.
