Abstract:

A method ( ) for manufacturing a precision part ( ) utilizing a non-precision fixture ( ). The non-precision fixture is precisely measured ( ) and modeled in a CAD program ( ) together with a model of the part ( ). The part model is nested ( ) into the fixture model, and a transformation matrix describing the movement of a coordinate system of the part during the step of nesting is recorded ( ). The transformation matrix may then be used to transform ( ) a tool path that had been developed for the originally designed shape of the fixture. Accordingly, imprecision in the location of a part within an imprecisely measured fixture may be accounted for during subsequent manufacturing operations.
