Invention Reference Number
A novel method has been developed to define an optimized preform geometry for individual features of thin-walled structures commonly encountered in aerospace and power generation. This approach leverages analytical modeling to improve machining reliability, prescribe workpiece deflection and reduces the need for dynamic adjustment of machining parameters. The outcome of the method also offers opportunity for productivity improvement.
Description
This innovative method employs analytical modeling to design preforms for thin-walled features with consistent static stiffness. The approach improves reliability during machining processes by prescribing consistent workpiece deflection caused by machining forces. While applicable to various manufacturing methods, this technology is particularly useful for preform design and manufacturing via additive technologies. Examples of application to industrial components are turbine blades and aircraft structural components. The method has the potential of integration with CAD and CAM systems during design and process development stages.
