The method of the present application includes machining complex part features in a flat metal sheet, and subsequently forming the machined flat metal sheet to have the desired shape and contours. Prior to the step of machining the complex part features, the method includes calculating a scaled location of the complex part features so that the subsequent forming step acts to translate and deform the complex part features into a desired location. The present application further includes a method for machining high performance metal alloy, such as titanium. Further, the present application includes a heated mandrel for applying heat to a high performance metal alloy, such as titanium, during stretch forming.
A method of machining a feature in a metal sheet, the method comprising:
A method of stretch forming a metal sheet on a mandrel, the method comprising:
The method according to claim 11, wherein the working fluid is oil.
