[Abstract]:In order to respond rapidly to the demand change of manufacturing process and to obtain the best economic benefit of machine tool resource cost, a structural modeling and simulation method of networked reconfigurable machine tool based on link relation graph is proposed. Based on the analysis of user requirements to obtain process information, a series of motions needed by reconfigurable machine tools to complete machining tasks are extracted, and a kinematic model of the basic functions of reconfigurable machine tools is established by using homogeneous transformation matrix. According to the functional requirements of machining operation, the topological structure of machine tool is described by using the method of link relation graph, and the formal representation of candidate reconfigurable machine tool is generated. According to the kinematics model of the reconfigurable machine tool and machine module, the suitable machine tool module is selected in the machine tool module library to synthesize the reconfigurable machine tool configuration to meet the needs of motion, structure and reconstruction. The effectiveness of the proposed method is demonstrated by the simulation of machine tool motion based on Internet and the verification of machine tool structure.
