Beschreibung

Riblet structures on surfaces can reduce the skin friction and the near wall shear stresses in turbulent flow up to 10%. Metal bonded grinding wheels have been applied to manufacture riblet geometries with smallest dimensions (s = 20 μm). For the generation of the necessary roof profile on the grinding wheel, electro contact discharge dressing (ECDD) is used, due to the absence of mechanical loading on the grinding wheel profiles. This paper shows the influence of the dressing parameters and strategies on the minimal dressable profile peak geometries and the ground riblet structures.
