Numerical Simulation Of Edge Milling Process And Milling Parameters Matching For The UOE Edge Miller

Edge miller is the main equipment which is used to process the edge of steel plate inthe production line for manufacturing oil and gas pipeline, to achieve the blunted edge andgroove of steel plate, which can meet the requirement of welding technology. In themilling process of edge miller, milling parameters is one of the key factors affecting themachining quality of steel plate and tool life, so how to get the reasonable millingparameters to achieve the optimum combination has become a issue of great theoreticalsignificance and practical value. Therefore, this thesis focuses on selecting the millingparameters of the UOE edge miller reasonably, the work of milling parameters matchingwas carried out, and ensured the final matching milling parameters for certain productionrequirements by the numerical simulation and calculating tool life in the milling process.Finally, the prototype system of milling parameters matching software for the UOE edgemiller was established, and information management of the edge miller and millingparameters were realized. The main content of this thesis is shown as follows:(1) The three dimensional models of edge miller’s key components were Established,then the working principle of UOE edge miller, the advantages of milling process, theinfluence of milling defect and the characteristics of the key components were studied,onthis base, the comprehensive evaluation for the necessity of this thesis was carried out.(2) The milling elements of edge miller had been analyzed, then combining with themilling theory knowledge the relationship between milling parameters and the sizes ofblunted edge and groove of different steel plate was deduced, and taking the millingprocess of19mm thickness of steel plate for example, the matching demonstration ofmilling parameters matching was carried out, finally what effect does the selection ofmilling parameters have on milling processing quality of steel plate was analyzed.(3) The key technologies of numerical simulation in milling edge process had beenstudied, and the material model of pipeline steel X80was established, then finite elementsimulation of the milling process was carried out, and the variation of cutting force wasanalyzed. By analyzing the deformation of the steel and calculating the tool life proved the matching milling parameters can meet the normal production requirements.(4) Aiming at how to manage the information of edge miller and obtain reasonablemilling parameters efficiently, combining with the demand analysis and function analysisof software development, concept design and logical structure design of the systemdatabase were carried out, then the prototype system of milling parameters matchingsoftware for the UOE edge miller was developed, and achieved information managementof the edge miller and milling parameters.
