Abstract: "KF with numerical methods is increasing modelling associativity"
Knowledge-based engineering (KBE) and knowledge driven automation (KDA) integrated
into environment of CAx system NX through KF technology provide storage of knowledge
and design experiences of users and provide re-use of this information as a structure
of standardized rules and procedures included directly into model geometry. It
can be knowledge represented by procedures based on numeric approach or by analysis
of qualitative criteria of geometry evaluation. Such a criteria are being used
for designing of shapes driven by complex definition. Used design procedures are
being modified according to the evaluation of these criteria. A number of such
design methods interrupt the associativity chain in common modeling processes.
Knowledge-based Applications enable user to integrate these tasks and approaches
directly into the environment of CAx system NX so the associativity gaps can be
bridged.
We would like to present examples of designs driven by complex definition, where
application of KF technology extends modeling associativity. There will be KF
features presented, which use numeric oriented procedures in combination with
qualitative evaluation of geometry. Up to now used methods (based on Open C/Open
C++ APIs) were replaced by KF features in these examples. Created KF features
were adapted to user, so he is able to modify easily their properties and parameters
through the use of same tools and procedures that are common for standard NX features
(UF Styler dialogs, interactive selection tools, expressions etc.). Used examples
represent existing KF based solutions in Machining Tool construction, Mold Design
and Tire production areas.
