OPTIMIZATION OF QUALITY OF THE CYLINDRICAL SUPERFINISHED SURFACES

摘要

The experiment and the subsequent analyses have afforded the selection of significant influent factors. The stone abrasive influences significantly the result of superfinishing by the abrasive material, grain type, and hardness; the dimensional variation of the abrasive stone has turned out to be of lesser importance for the final roughness; if the dimensional variation is accompanied by the change in the stone's pressure on the surface of the piece, then the geometric parameters of the stone abrasive become influent.rnThe final roughness depends on the characteristics of the processed piece, the most important being the initial roughness and the hardness (thermal and thermo-chemical treatment). Superfinishing is accomplished by means of different abrasives for pieces with different hardnesses (significance of the interaction abrasive-piece hardness). For industrial practice, the analytic model, in the form of the product of influent factors, is highly important. Such relations, providing information about roughness obtained by superfinishing and taking into account a set of input factors, have not been published in technical literature. The relation can be improved by additional experiments.
