Abstract

The invention relates to a method for ascertaining topography deviations of a dressing tool. The method includes executing a predefined relative movement of a dressing tool in relation to a dressable grinding tool, wherein during the execution of the relative movement, at least one contour region of the dressing tool is transferred into a transfer region of the grinding tool. A plunging body made of material which can be ground in the machine is provided. The transfer region of the grinding tool is moved into the vicinity of the plunging body by a relative infeed movement. A rotational movement of the grinding tool around an axis of rotation is executed. Plunging the transfer region of the grinding tool into the material of the plunging body, to thus perform a transfer of the topography of the transfer region into an imaging region of the plunging body. A scanning movement of the topography is performed of the plunging body using a coordinate scanning sensor and a computational ascertainment by means of a computer of at least one item of coordinate information, which permits a statement about the actual geometry of the dressing tool.
