Three-dimensional bending machine, FEM (Finite
element method), Performance and reliability evaluation
This study has been focused on the development of high
speed feeding type three-dimensional bending machine. It
is designed for manufacture of copper pipe for heat
exchangers. For the design of the machine, simulation of
bending process and structural analysis are carried out.
The analysis is carried out by FEM simulation using the
commercial software, DEFORM, MARC and CATIA V5.
The final results of simulation and analysis are applied to
the design of high speed feeding type three-dimensional
bending machine is successfully developed. After
development of the machine, performance and reliability
evaluation was carried out by a laser interferometer. In
order to improve the accuracy of this machine, the
maximum speed, positioning accuracy and repeatability
of feed were measured by the laser interferometer. Finally,
the machine has attained high performance and reliability.
