The invention relates to a power tool (10) having a tool receptacle (12), in particular a spindle, for receiving a tool (20), at least three machine axles (14, 16, 18) for positioning the tool receptacle (12), a machine control (22), which is designed to actuate the machine axles (14, 16, 18) such that the tool receptacle (12) is movable on a tool trajectory (W) which can be specified in a machine coordinate system, a machine frame (24) to which the machine axles (14, 16, 18) are fastened, and a fastening device (32) which is designed to fasten the machine frame (24) and a work piece (36) relative to each other. According to the invention, there is a measurement device (26) which spans a metrological frame and by means of which the position of the machine frame (24) can be determined relative to the measurement device (26), wherein the machine control (22) is configured to automatically carry out a method having the steps: measuring a position of the machine frame (24) relative to the measurement device (26), calculating the tool trajectory (W) in the machine coordinate system from a specified target trajectory (Z) in measurement frame coordinates of the measurement device (26) and moving the tool (20) along the tool trajectory (W) by means of the machine axles (14, 16, 18) such that a work piece (36) can be processed. |
