In this paper, an astral die was designed and constructed to produce anastral cup in the deep drawing operation by experimental work and numericalsimulation. The influence of radial clearance on drawing load, cup high, thedistribution of stress, strain and thickness along the side wall, minor and majoraxis were also studied. The deep drawing process was carried out to produce anastral cup with an inner dimension of (41.5mm × 34.69mm), and (30mm) heightdrawn from a blank sheet with a thickness of (0.7) and diameter (80) made of lowcarbon steel. A commercial program (ANSYS18.0) was used to perform thenumerical simulation. Three types of radial clearance equal to (1.1 , 1.2 , and1.3 ) are used to investigate the influence of radial clearance. It was found thatthe maximum value of the drawing load 55KN) recorded with radial clearanceequal (1.1 ). The process of a squeeze in the wall that occurred with the radialclearance (1.1 ) due to the difficulty of the flow of the metal to be exposed tomaximum tensile stress. The maximum effective stress (674MPa) and strain(0.973) were recorded with the clearance of (1.1 ) at the minor axis.
