Influence of Cutting Parameters and Tool Geometry on Topography of Hard Turned Surfaces

Three-dimensional topography measurement is a focus area of precision machining because it provides detailed information on the functional behavior contacting surfaces. The purpose this study to analyze how process parameters and edge geometry cutting insert influence topographical characteristics hardened 16MnCr5 steel surfaces determine favorable combinations technology parameter values based analyzed (Ssk, Sku, Sz, Sa, Sk, Spk, Svk). A research question whether can be substituted by each other or not. hard turning experiment was carried out full factorial design experiments, areas machined were scanned analysis variance, regression (response function), correlation analysis. It found that there are strong correlations between allow substitution one with another; main influencing feed rate for both types. contributions numerical regard among parameters, as well extent parameters.
