ABSTRACT Swift cup drawing test is the one of the formability characteristics evaluation for various sheet metals. The formability characteristics such as limiting Drawing ratio, maximum drawing load, maximum diameter of blank, depth of cup are to be evaluated. This test is related to drawing test. This test can be performed by using parameters such as friction, process parameters and with blank holder. In Swift cup drawing test, different diameters of circular blanks with constant thickness are drawn into cup until the fracture is occurred in the cup through flat cylindrical punch using the blank holder. The maximum diameter of blank is evaluated during the process; this is the diameter gives the successful formation of cup without fracture and after this diameter of blanks gives the fracture is occurred in cup during the test. The maximum diameter of blank is used to determination of limiting Drawing ratio. It is also called critical diameter of blank. The limiting drawing ratio is the ratio between maximum diameter of blank for successful formation of cup to diameter of punch. This indicates formability of sheet metals through this test. So formability can be represented as formability index. Hence the formability index expressed as limiting drawing ratio. This is also used to measure the deep drawability of sheet metals. The larger the value of limiting drawing ratio is to the better formability of sheet metal as per swift cup drawing test. In this test the formability characteristics of sheet metals such as alloys of mild steel, aluminum and cartridge brass are studied through finite element analysis. Key words : limiting drawing ratio, formability, maximum drawing load, forming characteristics and drawing
