In a device and method for determining a contact between a tool and a workpiece, which are displaceable relative to each other, the tool or workpiece being rotationally fixedly connected to a shaft, the device includes a measuring arrangement including a measuring scale rotationally fixedly disposed on the shaft and at least one position encoder disposed in a stationary manner relative to the shaft, and a processing device. The position encoder is adapted to scan the measuring scale and to generate position values indicating a position of the shaft. The position values are fed to the processing device, which determines contact between the tool and the workpiece by evaluating a progression of the position values and signals the result of the evaluation by the status of a displacement signal.
