Sheet metal bending is a useful process utilized in varying applications. Investigations in sheet bending find its importance as it is subjected to spring-back upon withdrawal of load and it differs based on material property and its size, etc. Therefore, maintaining specification of a bent object requires appropriate strategy to adopt. In this work, influence of thickness of galvanised iron sheet metal, punch radius and die corner radius on spring-back is considered. Three different values are taken for punch radius, die corner radius and thickness. Experiments are designed according to response surface methodology (RSM) and analysed by ANOVA technique. From various contour plots and surface plots, it is observed that sheet thickness has significant effect on springback. Influence of other two parameters is comparatively less if considered individually, but the combined effect is quite significant.

Abstract


Sheet metal bending is a useful process utilized in varying applications. Investigations in sheet bending find its importance as it is subjected to spring-back upon withdrawal of load and it differs based on material property and its size, etc. Therefore, maintaining specification of a bent object requires appropriate strategy to adopt. In this work, influence of thickness of galvanised iron sheet metal, punch radius and die corner radius on spring-back is considered. Three different values are taken for punch radius, die corner radius and thickness. Experiments are designed according to response surface methodology (RSM) and analysed by ANOVA technique. From various contour plots and surface plots, it is observed that sheet thickness has significant effect on springback. Influence of other two parameters is comparatively less if considered individually, but the combined effect is quite significant.
