Analysis of material transfer from a soft workpiece to a hard tool: Part II - Experimental verification of the proposed lump growth model

In this study, the lump growth model, described in an accompanying paper (d e Rooij and Schipper, 2000) is validated by means of experiments performed on a deepdrawing simulater. In the experiments, the influence of material a nd roughness properties of both sheet and tool on the galling behavior is d etermined For these experiments, a deepdrawing simulator and a selection of aluminum and zinc coated sheets with several (coated) deepdrawing tools ar e used. Good agreement is found between results of the lump growth model an d the sheer metalforming experiments.
