In this study, the affecting factors on the flatness of shim rings in conventional blanking were investigated through the experiments varying the ring widths and materials.
In this study, blanking experiments of shim rings were carried out varying the materials and the ring widths, and the effect of the ring width and mechanical properties of the materials on flatness of the blanked parts was investigated.

The Coulomb friction factor μ = 0.1 was applied for the friction between the tools and the sheet.
It was concluded that flatness of the blanked shim ring was affected by three factors of increasing manner of deflection angles during blanking, timing of separation and elastic recovery by separation.

Based on the results it is determined that the sequence of factors affecting radial strain corresponds to geometry of spun part, mandrel speed, planar anisotropy of the sheet.
Very significant feature of spinning is ability to produce components with high mechanical properties and smooth surface finish.
Although knowledge about the instant stresses, accumulated strains and damage evolution, which help to understand final properties of spun parts, have been developed by systematic investigation of the process using both experimental and theoretical techniques [3 and other], several gaps still exist in the knowledge of spinning mechanics, mechanical and structural properties of surface and sub-surface layers of spun parts (residual stresses, microstructure) and more information we need for precise prediction of workpiece material and geometry influence on strains distribution, too [2].
Chosen basic mechanical properties and facilities defining material plasticity (ultimate tensile strength (Rm), 0,2% offset yield strength (Rp0,2), elongation (A5), medium value of normal anisotropy (rs), planar anisotropy (D r) and strain-hardening coefficient (n)) are listed in Table 2.
