Design and optimisation of mandrel parameters for thin walled aluminium alloy tube NC bending

摘要

How to design and optimise mandrel parameters to improve forming quality has become a keynproblem for thin walled aluminium alloy tube NC bending. Therefore, in this paper, the design andnoptimisation method of the mandrel parameters is proposed based on finite element simulation. Itnis applied to two specifications of thin walled aluminium alloy tube NC bending, and the resultsnare verified by the experiments, which show that the proposed method is reliable.
