Collaborative manufacturing task information model and its model building method for complex parts

Aiming at the collaborative manufacturing of complex parts in networked environment,the collaborative manufacturing task information model and its model building method were studied.Collaborative manufacturing tasks and sub-tasks were defined.Collaborative manufacturing tasks and sub-tasks characteristics were proposed based on Logical Manufacturing Unit(LMU) and Logical Manufacturing Process(LMP).Information structure of LMU was established,and the information model and directed graph expression were studied.Collaborative manufacturing task decomposition process covering the design of LMU and LMP was put forward,and the design methods for LMU and LMP were provided.Finally,taking blade complex parts as example,the application and implementation process of collaborative manufacturing task decomposition were discussed.
