A pin-on-disk tribometer was used to investigate the influence of several parameters on the sliding friction coefficient between hard and deformable surfaces. Pin (1045 tool steel) and disk (aluminum 1100) were utilized to simulate the interaction of a harder tool sliding relative to a softer deformable workpiece. Friction coefficient results were obtained at 561 distinct operating conditions by varying the ball diameter (3.18, 6.35, and 12.70 mm), lubricant (oil B, oil A, and grease), sliding speed (0.1∼0.8 m/s) and normal load (50∼1200 g). Several relationships which characterize the behavior of the friction coefficient as a function of the shear factor, are established. the importance of these relationships, as related to stamping and forming processes, is discussed.
