Abstract
Briefly, in accordance with one or more embodiments, one or more thermal forming treatments may be predicted to achieve a desired shape and/or microstructure in a workpiece.
Claims17
A method, comprising:
- measuring at least the surface of a workpiece;
- determining a strain field based at least in part on said measuring of at least the surface of said workpiece;
- predicting one or more thermal forming treatments for a workpiece to achieve a desired shape and/or micro structure in said workpiece based at least in part on said determining of the strain field;
- performing a thermal forming treatment on at least one workpiece prior to said measuring of at least the surface of said workpiece, wherein said determining of the strain field results in an empirical strain field;
- and
- determining an empirical transfer function relating one or more process inputs to bend angle based at least in part on said empirical strain field.
