摘要
可重构机床是可重构制造系统的重要组成部分 ,其设计方法是实现制造过程可重构的关键。本文对可重构机床的模块化设计方法进行了探讨 ,系统分析了可重构机床区别于传统机床的模块化设计方法和特点。针对可重构机床设计任务驱动、运动重构的需求 ,在对机床结构进行拓扑图抽象描述的基础上 ,基于螺旋理论对加工任务进行运动分析和机床运动建模 ,提出了一种可重构机床模块化综合的设计方法 ,以生成满足加工任务运动需求的机床重构可行方案。
Reconfigurable machine tools (RMT) are a promisi ng technology for future machining systems, since they can not only provide cust omized solutions to the operation requirements, but also are cost-effective and very responsive to the changes of operation requirements. Modularized design of machine tools is a key enabling technology to the reconfigurability of RMT. Thi s paper investigates the modular design methodology of RMT and systematically an alyzes the different design features of RMT from conventional modularized machin e tools. A method for systematic synthesis of reconfigurable machine tools is pr esented, which uses screw theory for motion representation, and function decompo sition and graph theory for structural synthesis.
