FEM numerical simulation in combination with theoretical analysis and physical modelling is feasible and credible in the research of tube NC bending process.However,tube NC bending numerical simulation and experiment process needs to deal with large numbers of modelling parameters and massive simulative results.For storing and managing these data as well as sharing and reusing valuable knowledge accumulated by researcher,in order to improve precision and efficiency of research of tube NC bending,FEM numerical simulation management system of tube NC bending was studied and developed by means of relational database technology.The results indicate that the system could guide tube NC bending numerical simulation and experiment process accurately and effectively,and also provide quick and effective expertise for operator throughout the practical manufacturing operation.
