In this paper, the grinding of hard-material-coated forming tools on a machining center is presented. The coated materials have to be machined mechanically because of the insufficient surface quality and form errors resulting from the thermal spraying processes. During the fundamental investigations two different tungsten carbide coatings have been machined by applying super abrasive grinding tools consisting of four different bond systems. To identify the suitable grinding tools, the process forces and the surface roughness values have been carried out by a screening design of experiments.
