บทคัดย่อ

In recent years, the Z-bending process was rarely investigated, especially for the asymmetrical Z-shape bending process. This causes the lacks of understanding on bending mechanism and spring-back characteristics and results in the difficulty in die design and process control for the spring-back characteristics. In the present research, therefore, the wiping asymmetrical Z-bending process was examined by using the finite element method (FEM) and laboratory experiments. On the basis of the stress distribution analysis, the different of spring-back characteristics between the symmetrical and asymmetrical wiping Zbending processes were investigated and clearly identified. In addition, the effects of working process parameters, including bend angle and tool radius on spring-back characteristics were investigated and clearly identified via the changes of stress distribution analysis as well. To verify the accuracy of the FEMsimulation results, the laboratory experiments were carried out. The experiments were carried out to validate the FEM simulation results. The FEM simulation results showed a good agreement with the experimental results with reference to the bend angles. ฉ Copyright 2016 by SCITEPRESS - Science and Technology Publications, Lda.
