A common design technology of machine products is to verify whether an assumed physical structure correctly implements the specified function or not. In the case of porous superfinishing stones, however, the design technology depends on the trial manufacture and test. That very empirical way of designing is requiring urgently to discuss the engineered design. Therefore, the establishment of an integrated design procedure, from producing a preliminary drawing of stone structure in conformity to the specified cutting performance to quantifying the manufacturing parameters of the stone, has been intended. In this paper, the seemingly complex and irregular structures of the superfinishing stones have been described using fractal geometry which provides a geometric model for the stone structures at the same time. Further, the intrinsic parameter characterizing fractally the stone structure has been related experimentally to the manufacturing parameters and the cutting performance of the stones.
