Abstract：

Combined with the traditional deep drawing process, the plastic forming process of the scale effect was represented using material intrinsic length, and based on 3D finite element analysis model, the micro deep drawing technology in pure aluminum L2 was simulated and analyzed. The diameter of micro deep drawing is 1.41.6 mm, the vertical depth is 1.21.4 mm and the force is 2.67 N. The test results and simulation results of micro deep drawing are in good agreement. The constitutive equation with intrinsic length can be used for the micro deep drawing process of the finite element numerical simulation.
