Abstract
In a method for checking a contour of a workpiece, a tactile switching touch probe with a shaped probe element is clamped in a machine tool and connected to a control facility. The touch probe is guided, preferably multiple times, with a different distance or different deflection of the touch probe, along a nominal contour of the workpiece. It is checked whether the touch probe generates a switching signal or loses a switching signal, indicating to a contour deviation. A machine tool and a simulation tool constructed as a digital twin are also disclosed. This enables a fast, simple and cost-effective check of the dimensional accuracy of workpieces machined or produced in the machine tool.
