Abstract

En 中文

The tools and processes available in a given shop greatly influence the way in which manufacturers view a part and the way in which they decompose it into machinable volumes, or features. Likewise, a feature recognizer should be able to produce a different feature decomposition when different tools are available. Additionally, it should be easy for a user to add new tool descriptions to the system in order to maintain and customize the feature recognizer. We address this challenge in two parts. First, we present an extensible representation which allows users to easily add their own custom tool descriptions to a feature recognizer's knowledge base. Second, we present CUSTOM-CUT, a tool-based, resource-adaptive feature recognizer. CUSTOM-CUT accepts the user-defined cutting tools as input and automatically identifies the areas of the part that can be cut using the custom tools. We call CUSTOM-CUT resource-adaptive because the features it identifies will be different if it is given different cutting tools. The advantages of this is that it is easier for the user to maintain and customize and provides greater assurance that the features identifies are actually machinable with the given set of equipment.
