A high performance disk machine capable of simulating both radii of curvature, rolling and sliding speeds of spur gears was built. The simulation program was conducted using both a gear rig and a disk machine. The point chosen for simulation is situated just below the pitch circle. The geometric and dynamic conditions at that point were reproduced. The damage observed in both cases for three different metallurgies and one loading program is presented. Qualitative results are most encouraging. Identical forms of damage are observed when, the mechanical parameters which define the contact condition (CMD), the gear and disk material, and the lubricants are the same.
