    DETAILED DESCRIPTION

    [0035] FIG. 1 shows a potential sequence of a preferred embodiment of the proposed method. First, various acceleration values are detected by a sensor. These here can be the accelerations along the three coordinate axes of a coordinate system. In the context of the invention, these accelerations are referred to as “axial accelerations”. They are illustrated in FIG. 1 as accelerations a_x, a_y and a_z. Moreover, angular accelerations can be measured with the sensor. These here can be the angular accelerations about the three coordinate axes of the coordinate system. The angular accelerations are illustrated in FIG. 1 as accelerations w_x, w_y and w_z. The data detected by the sensor can be filtered and evaluated, for example, by a control device of the machine tool. The evaluation includes, for example, the determination of the deflection of the machine tool when switching on the latter, as well as an assignment of this determined deflection to an operating mode of the machine tool. The operating modes of the machine tool can preferably be a manual operation as the first operating mode and a stand operation as the second operating mode. A large deflection of the machine tool at start-up can be interpreted, for example, as the manual operation of the machine tool (shown in FIG. 1 as “Yes”), while a small deflection of the machine tool at start-up can be interpreted as the stand operation of the machine tool (shown in FIG. 1 as “No”).
