The Design Of Logistics Management System For Digital Workshop Of Gear Machining

Along with the rapid development of modern manufacturing industry,the demand of the gear is more and more diversified and personalized,the type and amount of relevant manufacturing resources increase,so the workshop need to change the backward mode of production,to design and build a more efficient digital workshop,which put forward higher requirements and challenges for the logistics management of the digital workshop.Logistics management of production workshop needs manage the most of the manufacturing resources,because all kinds of resources has characteristics that the similarity and the use of different,the product variety and flexibility under the condition of high production requirements,confusion of production problems appears most often,which seriously affect the production efficiency and quality.In addition,at present,the way of the most of the gear cutting machine tool workshop logistics management is backward,it is out-sync of information and material flow,low degree of informatization and digitization,and it is difficult to unified management and coordination related to production,led to a lot of invisible cost of production.Therefore,this paper takes the logistics activity in the machine tool gear processing as the research object,based on the information management of logistics,and designed the digital workshop logistics management system of machine tool gear processing.First of all,the machine tool gear processing workshop production logistics and logistics management are summarized analysis,problem and demand of logistics management,determine the logistics management system should have code query management,basic data management,logistics,logistics scheduling,logistics management,real-time data display,coding identification,the basic function such as logistics information input;The network connection mode between the upper management center and the management end of the workshop and the underlying equipment was designed,and the business process of logistics management in the workshop was explained.Material flow static information model is established,including the manufacturing resources of static,dynamic logistics information model and information model artifacts and blade fixture position information and status information,can provide a unified description and expression of the activities of the various stages of the production process and characteristics of the method;Combination machine tool gear processing technology characteristics and current situation of chongqing machine tool group workshop on workshop through put between each operation unit and system arrangement are analyzed,and the overall design of the digital workshop logistics management,and describes in detail from five aspects.Secondly,using the Witness simulation software for processing activities path tracking mode,system target,logistics,personnel arrangement and workshop layout gear processing workshop is set up the digital model of logistics management,implementation is based on data driven system simulation,determine the design modeling goals and related elements,find system bottleneck through data analysis and optimization method;Run the model and analyze the data again,and confirm that the optimized scheme has improved the original production bottleneck and is feasible.Then,a logistics tracking method for machine tool gear processing is proposed,which can generate the unique coding of workpiece and tool fixture with existing coding rules.The identification of the unique identity of the workpiece and the tool holder with laser marking;The dynamic information of the position and state of the workpiece and the tool fixture was recorded by using the scanning code in the machine tool and the logistics point terminal,and the logistics tracking of the digital workshop was realized.Determine B/S system architecture and divide the system into user layer,high-level application layer,processing layer and support layer;The function of the logistics management system is designed in detail from two aspects of management and processing operation,and the internal relation and interaction between each function of the system are described.The time sequence of information transfer between each person role and function module of the system is explained by establishing the operating process of the system.Conceptual design and logical design for the database of logistics management system.Finally,it designs of machine tool gear processing digital workshop logistics management prototype system which based on the logistics simulation and analysis,system architecture design and function design.It describes each functional module of the system in detail;Display the actual application of the system.
