✦ Synopsis
Using a pin-on-disk tribometer, an experimental procedure is introduced for characterizing the sliding friction between a hard tool or .
Ž . die and a deformable workpiece surface. Sliding friction coefficient data is obtained at 152 different operating conditions for a wedge-shaped steel pin contacting an aluminum 1100 disk. From the experimental data, the influence of normal load, lubricant, sliding velocity and disk surface roughness on the friction coefficient is determined. By plotting the sliding friction coefficient as a function of the shear factor, t , of the disk material, three distinct friction regions are found. The overall nature of the friction in each region is then k established and implications of the friction regions to precision manufacturing processes is discussed.
