摘要：This paper deals with finite element analysis to
know the thickness and diameter reduction of a single pipe. The
tube forming process begins with a straight pre-cutting tube.
There are many variables in the pipe bending process. In
particular, there is a difference in the accuracy of the bend
depending on the shape of the mandrel. Through this analysis,
we want to find the part where the reduction direction of the
mandrel drastically occurs. In this process, the more the
number of mandrill, the better the reduction in diameter. Also,
it was concluded that the movement speed of the pressure die
should be controlled to reduce the thickness.
