Magnesium alloy thin-walled parts

Abstract:
Through the use of Deform finite element software to model and analyze the thin-walled magnesium alloy parts of aerospace, the law of the resistance to cutting of the magnesium alloy in the cutting process is simulated, and the cutting speed, the amount of cutting, and the amount of cutting are summarized. The degree of influence of the resistance, finally finds the main factors that affect the resistance to the knife, which can guide the production practice, correctly select the cutting parameters, effectively reduce the impact of the resistance of the knife on the bending deformation of the part, and reduce the actual amount of the knife and the theoretical amount as much as possible. The difference of the knife amount solves the long-standing problem that the deformation of the knife affects the dimensional accuracy. For practical verification, through orthogonal experiments on thin-walled magnesium alloy parts that are often encountered in production practice, the actual size of the outer circle of the part after each test is measured, and the actual amount of the part is calculated, and compared with the finite element analysis Compare the results.
