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