Abstract
PurposeThe aim of this paper was to confirm the hypothesis that it is possible to conduct normal honing by mechanical method, providing the prescribed quality of cylinder liners. For this, cutting parameter optimization is needed.Design/methodology/approachNormal honing was performed on grey cast iron with lamellar graphite and mostly pearlitic microstructure of metal matrix. Cutting speed, feed rate and specific pressure during metalworking were varied and accordingly, a mathematical model for processing of results by the least squares method was proposed. Surface texture was controlled by scanning electron microscope.FindingsA mathematical model describing the influence of cutting speed, feed rate and specific pressure during metalworking was devised. At the same time, surface texture was adequate, with geometrically appropriate crosshatch pattern, without standing‐out material and mashed graphite lamellas.Originality/valueIt was found that normal honing may be done by mechanical means, providing exceptional quality of lubrication. The most influential metalworking parameter was shown to be specific pressure.
