Abstract

Acceleration sensors can be used to detect failure and measure deformation in metal forming processes. In this study, the applicability of acceleration sensors for analysis of the metal forming process was studied. Magnesium alloy sheets (AZ31B-H24) with the thickness values of 1 mm, 2 mm, and 3 mm were used to perform the three most basic processes in the metal forming process such as tensile, bending, and 2D-draw bending test. The sensors were attached to the material. Acceleration signals occurring during material deformation were measured. For each experiment, we analyzed the changes in the acceleration of the sensor. In tensile deformation, a large acceleration occurred at the point of material failure. In bending, there was no significant acceleration at the point of material failure. The bending angle of the material was measured using the acceleration components. It was found that acceleration sensors can be used to detect fracture and measure deformation angles in the metal forming process.
