Galling in Deep Drawing
Galling in Deep Drawing
Contact in deep drawing can be divided into different scales, see figure 2. FEM simulations are typically concentrated on the macro scale, while galling plays a role on the smaller scales. On the meso scale, the relatively rough sheet is flattened when it is in contact with the smooth tool and plateaus are formed on the sheet. On the micro scale, the hard tool asperities plough through the flattened sheet plateaus. These ploughing asperities pick up material from the sheet metal. • Experiments are performed with a spherical shaped tip of tool material which scratches against a metal sheet, in order to simulate the micro scale behaviour. From these experiments the growth behaviour can be studied, see figure 3a.
