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

The control of mechanical springback 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 angle of bent connector the elastic-plastic incremental analysis has been carried out includiong friction effects and material characteristcs 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.
