Abstract

A method and a system for designing a spline coupling, comprising the steps of creating signals representing a spline coupling knowledge base of information having a plurality of rule signals with respect to a corresponding plurality of parameter signals of associated elements of the spline coupling, wherein the spline coupling knowledge base comprises at least one data value signal for each one of the plurality of rule signals. Included are the steps of entering a desired data value signal for a selected one of the plurality of parameter signals of an associated element of the spline coupling, and comparing the entered desired data value signal for the selected one of the plurality of parameter signals with the corresponding at least one data value signal in the spline coupling knowledge base for the corresponding one of the plurality of rule signals. The steps also include creating signals representative of a geometric representation of the selected one of the plurality of parameter signals of the associated element of the spline coupling if the result of the step of comparing is such that the entered desired data value signal for the selected one of the plurality of parameter signals is determined to have a first predetermined relationship with respect to the corresponding at least one data value signal in the spline coupling knowledge base for the selected one of the plurality of rule signals.
