Production of coil cylindrical springs is the most common process of metals
shaping by the process of cold deformation. Accuracy is the most important factor in spring production industry. One of the mainoccurences during manufacturing of these parts is elastic straightening i.e. elastic deformation in the material after removal of tool. After formation, elastic straighteningcauses deviation from designed (desirable) shape and as a result products have quality problem and difficulties during installation.
Hence, control of elastic streightening in the process of production of coil (helical) components is one of the key problems during production.
This paper presents results of physical experiment aiming to obtain an adequate regression models which serve for anticipation of elastic streightening and force in the spring at certain length of deformation, which is in function of material and
its constructive and geometrical characteristics.
