Evaluating the real profile length in turning of carbon steels

Abstract

The real profile length constitutes a hybrid parameter in surface metrology which is rather neglected in literature, albeit it affects or controls sometimes surface functional properties like corrosion resistance, adhesibility, wear, lubrication etc. Real profile length values are assessed here in turning of different carbon steels under a wide range of cutting conditions variation leading to a variety of relevant textures. Useful quantitative information for evaluation and modeling of the turning process is provided, as well as correlation is sought with other topography parameters and the statistical distributions over the turned surfaces are determined. Also, possibilities of turned profiles discrimination are discussed.
