The paper deals with numerical simulation when optimizing the production of gutter corner for rainwater systems. The deep drawing process has been numerically simulated using Pam Stamp software by ESI Group. Blank geometry, material quality and process parameters have been optimized. The elasto-plastic material model by Hollomon combined with orthotropic Hill 48 yield law were used in numerical simulation to describe material behaviour. These were defined on the results from tensile test, normal anisotropy ratio test and strain-hardening test. Simulations were done for two different quality of the hot deep galvanized steel sheet - DX54D+Z and DX56D+Z. As a results, process window for the gutter corner produced by deep drawing process have been found. Stated optimal process parameters were verified by experiment when lamination tooling concept has been adapted for production of the punch.
