Parametric component design process
A method for implementing a component design model includes defining a component design specification, defining at least one variation mode parameter of a component manufacturing process, constructing a parametric model relating the at least one variation mode parameter to the component design specification, determining an expected component output based on the parametric model and comparing the expected component output to at least one as-manufactured component, and defining the parametric model as accurate in response to the expected output component matching the at least one as-manufactured component within a predefined degree of accuracy.
1. A method for generating a component design model comprising:
defining a component design specification;
defining at least one variation mode parameter of a component manufacturing process, wherein the at least one variation mode parameter includes each of shift, tilt, shrink, bend, and twist;
