To assess the tool-workpiece compatibility in metal forming, a friction test is carried out on a strip-ironing type tribometer, which can estimate quantitatively the effect of new surface generation during the process and sliding travel on galling. The workpiece is mild steel and the die materials are tool steels of various kinds, cemented carbide, ceramics, and surface treated steels. The compatibility is estimated through examination of the frictional characteristics, observation of the frictional surface, and the surface appearance of products. The effect of lubricants on compatibility is also examined.
