  • Precision Casting - an overview | ScienceDirect Topics

    The machining or mechanical working processes of propeller blades after casting have undergone major changes in many manufacturers’ works since the advent of numerically controlled machine tools. Early usage of automated machinery required the use of a solid pattern, which acted as the master blade from which the machine could work a new casting.
