摘要/Abstract

摘要： CWE（Cutter/Workpiece Engagement）计算是加工过程仿真与优化研究中的一个重要问题。在CWE计算过程中，工件模型不断被更新，其几何越来越复杂，计算开销越来越大。为了提高CWE计算的效率，提出了一个基于MAS（Multi-Agent System）的CWE计算方法。该方法将CWE计算的任务加以分解，利用Internet/Intranet中的各个Agent进行分布式计算，对计算的结果进行组装得到最终结果。最后给出了原型系统的实现和一个实际计算的例子。

Abstract: Cutter/Workpiece Engagement（CWE） extraction is an important problem in process modeling.One approach is to use a B-rep solid modeler to perform the calculations.However，this can have a high computational overhead especially for complicated workpieces.This paper presents a Multi-Agent System（MAS） for B-rep based CWE extraction that allows distributed processing of the modeling steps over the Internet.A task scheduling strategy is presented for decomposing and distributing the task over the framework according to the idleness of the agents.Finally a prototype implementation and an example are given to show the effectiveness and efficiency of the system.
