AB - This paper developed a methodology for estimating Abbott-Firestone curves from
the roughness parameters of the material probability curves. The surface
roughness profile obtained in plateau-honing processes is the superposition of the
effects of the two processes used to generate it. At first, a honing is performed
with which the characteristics of valleys are generated, honing base, and after this
honing base, a finishing honing is performed, a plateau operation to reduce the
peaks of the base honing profile without modifying the characteristics of the
valleys of the base profile. In the functional behaviour of the surface, the valleys
will contribute to the retention of oil and the flat areas will contribute to reducing
friction with the oil retained in the valleys and to improving watertightness. To
characterize this type of roughness obtained by the superposition of the roughness
generated by two processes, material probability curves are suitable, in which the
roughness of each process is characterized by the slope of a line, and the point of
intersection of both lines corresponds to the transition zone between plateaus and valleys. The roughness parameters other than those of the probability curve do not
adequately characterize the roughness obtained by processes such as plateauhoning, since they are calculated on the total height of the roughness profile and do not separate the effects of the processes that have been used to obtain it, which
means that the contribution of each of the processes to the roughness profile
cannot be differentiated.
