Abstract: Due to the complexity of machined roughness profiles and the fact that different surface characteristics exist in view of function, a multi-parameter analysis of roughness is recommended by international surface metrology standards, as well as by recent research projects. A multi-parameter surface analysis according to ISO 13565-2:1997 standard is performed on longitudinally and face turned surfaces of Ck60 steel over a wide range of feed and cutting speed values in order to stablish subsets of mutually unrelated roughness parameters; each one of them would describe different features of the surfaces with the criterion for this purpose being insensitivity to cutting conditions. The correlation of each parameter considered is examined with the machining conditions; statistical regression models with varying correlation coefficients are developed. It is concluded further that a minimum concise set of independent parameters towards turning process control and research would incorporate R_a, R_sk, R_Rku, and R_DelQ.
