Application of Modern Machinery Manufacturing Process and Precision MachiningTechnology
Complex thin-walled parts of aluminium alloy are susceptible to large deformation during machining by the force of milling cutter and fixture,which reduces the machining accuracy of the workpiece.In order to solve this problem,the research process takes the thin-walled aluminium alloy rail as the object of analysis,establishes the stress calculation model of aluminium alloy material during cutting,and simulates the optimal clamping method,clamping force and machining parameters with the help of finite element simulation technology.The results show that it is suitable to adopt the clamping method of setting the pressure plate at the bottom and the support points on both sides for this kind of components,and the deformation and internal stress can be reduced to a lower level by reasonably controlling the clamping force and the machining parameters,so as to realise the precision machining.
