Deep drawing and its spring back have been analyzed by the finite element method. Together with the numerical analysis, experimental confirmation has been carried out on the same deep drawing process.
It shows sound agreement between the numerical analysis and experiment.
In view of the experimental and numerical results, the punch radius appears to the most significant factor in the formation of oil canning.
The other factors such as die radius, and punch die clearance are negligible.
