One of the processes ofsheet metal formingdefined as Hydromechanical deep drawing. In this paper, changing the minimum thickness of the sheetin the hydro-mechanical deep drawing process is reviewedexperimentally and numerically.For this purpose, the hemispherical parts in the laboratory process are used.Numerical ABAQUS softwareis used in order to solve the numerical of the hydro mechanical deep drawing process of hemispherical parts.Coefficients of friction between the punch, sheet and clamp

In order to confirm the results of finite element simulation a studyconducted with laboratory equipmentand the results were compared.It was noted that no wrinkling and thinning parts were made in the flange.
