Abstract : It shows detailed stages, starting from the initial stages of design to material selection, then to casting, forging, and CNC machining up to final assembly with strict quality control. It emphasizes precision engineering for that great performance durability. Finally, it discusses best practices on how to advance manufacturing in terms of efficiency and minimize the effects on the environment with a comprehensive guide for engineers, manufacturers, and industry professionals devoted to producing reliable and efficient hydraulic turbine blades. These traditional methods are casting and forging, which discuss the advantages and limitations that follow. Advanced techniques such as precision CNC machining, additive manufacturing, surface treatment processes including heat treatment, and coating application processes are extensively reviewed to show their role in enhancing blade performance and durability. Quality control is elaborately focused on with detailed procedures for NDT or non- destructive testing.

Keywords : Dovetail, Vaccum Side, Hub, Blade Velocity, Airfoil, Propeller, Shank.
