Effect of Cutting Materials on Roughness in Turning

POLAK PAVEL, ŽITŇANSKÝ JAN, DOSTAL PETR, KOLLAROVA KATARINA. 2015. Eff ect of Cutting Materials on Roughness in Turning. Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 63(5): 1523–1528. This paper focuses on demonstrating the eff ect of cutting materials and the geometry of cutting blades on roughness during the turning of machined surface. Experiments have been targeted at measuring roughness when turning a sample of 11 523 steel at constant parameters of shi and depth of cut and under variable values of spindle speed. Measurements were performed by using replaceable cutting blades of diff erent types and parameters. Results were evaluated in terms of the eff ect of diff erent properties of cutting blades and variable values of spindle speed.
