COMPARATIVE ANALYSIS OF THE SHAPE CHANGE WHEN A PRODUCT IS PRODUCED BY FREE-FORM BENDING

The paper presents a comparative analysis of the shape change of a rod when it is deformed in a moving die using the Abaqus and Qform software packages. The approaches to determining the shape of a profile formed by a moving die are analyzed. Methods for analyzing the shape change when a product is obtained by free-form bending, based on predicting the volumetric unevenness of metal deformation in the processes of pressure treatment and determining the product curvature, are considered. For the process of modeling the bending of a product in a moving die, a rod was selected, as well as an algorithm for moving the moving die and feeding the rod. As a result of the simulation, it was found that the resulting product models in these software systems are identical in geometry. Based on the methods of analyzing the shape change when a product is obtained by free-form bending, we analyzed the uneven distribution of deformation parameters and determined the curvature of the workpiece during deformation. It was found that a significant deformation irregularity is observed in the workpiece, which is caused by the chosen scheme of deformation. Proposed approaches for further research.
