Abstract

A modularized design method of a reconfigurable machine in the computer numerical control technical field comprises the following steps: step 1, establishing a movement model of a rigid body in space; step 2, carrying out task analysis, and resolving the task processing information transmitted by an upper machine into a series of functions of the reconfigurable machine; step 3, carrying out topological configuration and designing the function topology of the reconfigurable machine through a graph theory to express the topological relation between functions and select the topology of the reconfigurable machine; step 4, according to the topology of the reconfigurable machine selected in step 3, establishing a parameterized module library and selecting mechanical modules from the library to assemble and generate the whole reconfigurable machine. The invention can reduce the development cycle and cost.

Description

technical field [0001] The invention relates to a system in the technical field of computer-aided mechanical design, in particular to a modular design method of a reconfigurable machine. Background technique [0002] A reconfigurable manufacturing system is a manufacturing system that has the two functions of actively adapting to changes in the external environment and passively responding to internal disturbances in the system. The function and production capacity of the system can adapt to changes in product varieties or changes in market demand. The six characteristics of a reconfigurable manufacturing system are modularity, openness, scalability, integrability, transformability, customization, and diagnosability. Among them, modularity is the core feature of reconfigurable manufacturing system. A reconfigurable manufacturing system consists of an upper-level planning and scheduling controller and a lower-level reconfigurable machine. As the smallest unit of a reconfig...
