Feature-based fixturing analysis for machining parts represented with multiple sets of features

摘要

In a feature-based model, a typical approach is to represent a part with a single set of features. However, in part with feature interactions, there may exist multiple sets of features to represent the same part. The multiple sets of features represent different ways of machining the part. It is necessary to analyse and evaluate the various sets of features to measure their performance when using different machining methods. In a machining process, different fixturing parameters are required when different sets of features are used for machining. The purpose of this research is to determine a 'good' set of features that is more suitable from the fixturing point of view.
