Abstract
Production time and costs of milled turbine blades can be significantly reduced by increasing the spacing of the cutter paths. In order to quantify the effect of the resulting coarse milling groove texture on profile losses, two different turbine cascades with various cutter path parameters were investigated in a linear cascade wind tunnel. It was found that neither the milling groove spacing nor the stagger angle measured between the grooves and the core flow direction affect the profile loss significantly in the range of typical industrial applications. Therefore, coarsely milled surfaces may be used for cost reduction within the milling parameter ranges investigated.
