The effect of several material and system parameters were investigated to determine their influence on the frictional behavior of the ABS materials. These parameters included: the time dependence of friction under static load, friction-normal load relationships, surface roughness, internal lubrication, friction-velocity relationships, and system stiffness. Four basic types of frictional behavior were observed - steady sliding, a single stick followed by steady sliding, non-sustained stick-slip oscillations that decayed after several oscillations, and stick-slip oscillations lasting several minutes. Several observations were made regarding the experimental results. It was observed that increasing surface roughness decreases the unstable behavior of the materials. Also, decreasing normal load decreased unstable behavior. A relationship between the friction-velocity curve, stick-slip, and the critical velocity at which stick slip disappeared was observed.
