The tooling master model includes a tooling geometry for the part, and the manufacturing context model includes a number of tooling features. A system for generating the tooling master model includes a computer aided design (CAD) system configured to receive the parametric model and to generate the manufacturing context model from the parametric model.
BACKGROUND OF INVENTION This invention relates to a method and system for creating a tooling master model for manufacturing parts, such as turbine blades, and to a method for manufacturing parts.
SUMMARY OF INVENTION Briefly, in accordance with an embodiment of the present invention, a method of creating a tooling master model for a manufacturing process for a part is disclosed. The tooling master model includes a tooling geometry for the part. The method includes generating a manufacturing context model from a parametric model for the part. The manufacturing context model includes a number of tooling features.
DETAILED DESCRIPTION A method of creating a tooling master model 134 for a manufacturing process for a part 10 is described generally with reference to the flow chart shown in FIG. 1. The method includes generating a manufacturing context model 136 from a parametric model 70 for the part 10. Parametric model 70 is a representation of part 10, for example a computer model usable within computer aided design (CAD) software, in which part geometry is described in terms of features, such as holes, lines, curves, chamfers, blends, radii, well defined shapes, user defined shapes, shapes from shape libraries etc. and parameters associated with and between these features. In other words, parametric model 70 is a parametric model of the part design for part 10. At any given time, the parameters take on specific numerical values or relationships between parameters. Desirably, this parametric representation of part 10 is flexible, in that part 10 is described by a set of parameters, for example length, width, and height, all of which can vary. Consequently, parametric model 70 can be altered all at once by changing the value of one or more of the parameters. Moreover, a parametric model applies to an entire part family. Parts belonging to a part family differ only with respect to the values of the parameters describing the parts or with respect to small topological changes, for example different hole sizes or positions corresponding to different machining steps.
