This study uses the Taguchi method and a commercial package, AutoForm, to analyse the effects of process conditions on the depth of the drawn cup in micro deep drawing. The brass (JIS C2680) sheets with the thickness of 0.2 mm were used to produce the micro cups with the diameters of 3 mm and 1.5 mm, respectively. The investigated process conditions include the diameter of the blank, the radii of die and punch, the blank holder pressure, the punch speed and the clearance between the punch and die. The results show that the diameter of the blank, the radius of the punch are the main parameters affecting the depth of the drawn cup in the micro deep drawing process.
