MOBILE MACHINE TOOL

The invention relates to a mobile machine tool (10)， namely a hand-held machine tool or semi-stationary machine tool， for machining a workpiece (W)， wherein the machine tool has an in particular plate-like guide element (30) having a guide surface (32) for guiding the machine tool on the workpiece (W) or guiding the workpiece (W) on the machine tool， wherein the machine tool has a drive unit (11) with a drive motor (13) for driving a tool receptacle (14) arranged on the drive unit (11)， wherein the drive unit (11) is displaceably mounted on the guide element (30) by means of a bearing arrangement (35) for adjusting at least two actuating positions (S0， S1， S2) of the tool receptacle (14) relative to the guide surface (32)， wherein at least one actuating position (S0， S1， S2) corresponds to a workpiece machining position， in which a working tool (15)， in particular a separating tool， arranged on the tool receptacle (14)， is in contact with the workpiece (W) in a workpiece contact region， in particular cuts into the workpiece (W). According to the invention， it is provided that the machine tool has at least one tool sensor (61， 62) for detecting the workpiece contact region and at least one position sensor (63， 64)， which is separate from the tool sensor (61， 62)， for detecting a relative position of the drive unit (11) relative to the guide element (30)， and that the machine tool comprises an evaluation device for evaluating sensor signals of the position sensor (63， 64) and of the tool sensor (61， 62).
