Surface topography after deep rolling with milling kinematics

Abstract Deep rolling is a machining process which used to decrease roughness and induce compressive residual stresses into component surfaces. A recent publication of this research group showed possibilities predict the topography during deep bars in lathe. Although can be milling machine flat specimens, it still unclear, whether predicted similar extend using application. To investigate influence parameters on topography, three experimental stages are performed paper cast AlSi10Mg. First, single-track experiments under variation pressure $$p_w$$ p w find relationship between indentation geometry. Here, logarithmic characteristics could found that achieved relatively high agreement. In second stage, surfaces prepared multi-track rolling. lateral displacement $$a_b$$ a b varied. The rolled were compared an analytical model for calculation theoretical based first stage. limits prediction shown because similarities measured only occurred certain pressures displacements . further limitations procedure, novel tool concept, utilizes rotation spindle, third generated surface also interpreted as periodic sequence spheric indentations whereas differed from expected As result paper, predictability after specimens known (minimum $$p_{w,minAlSi10Mg}$$ , m i n A l S 10 M g = 5 MPa minimum $$a_{b,minAlSi10Mg}$$ 0.25 mm) results regarding final concept presented.
