Finite element analysis of the stress-strain condition and computer aided modeling of bending tools for robotic assembly

The control of mechanical spring-back appears as a very important problem in the designing of bending tools for electronic components which are intended to be assembled by robot. This is because robotic assembly requires very tight shape tolerances to prevent process break-downs. In order to determine the inevitable spring-back of a bent connector the elastic-plastic incremental finite element analysis has been carried out including friction effects and material characteristics such as work hardening. The accuracy of the simulation results, spring-back angle and the residual stress distribution after unloading are discussed comparing them to the experimental results.
