Abstract
The invention relates to a measuring body for verifying geometrical deviations in a 3-axis machine tool comprising a base plate, a first wall which is arranged on the base plate and projects perpendicularly from the base plate, a second wall which is arranged on the base plate and projects perpendicularly from the base plate wherein a first row of holes and a second row of holes are formed in the base plate, wherein the first wall has, at an upper exposed region, a stepped region with a plurality of steps and wherein the second wall has, at an upper exposed region, a stepped region with a plurality of steps. The invention further relates to a 3-axis machine tool having a measuring body of this kind, and to a method for verifying and compensating geometrical deviations of the 3-axis machine tool.
