Patent ID: 11420274

Abstract:
A mobile machine tool (10), namely a manually-operated machine tool (10) or semi-stationary machine tool (10), for machining a workpiece (W), wherein the machine tool (10) has a plate-like guide element (30) with a guide surface (32) for guiding the machine tool (10) on the workpiece (W) or the workpiece (W) on the machine tool (10), wherein the machine tool (10) has a drive unit (11) with a drive motor (13) for driving a tool holder (14) arranged on the drive unit (11) in order to hold a work tool (15), wherein the machine tool (10) has a tool sensor (61, 62), the detection range of which (EB1, EB2) is directed at at least a partial region of the machine tool (10), and wherein the machine tool (10) has an evaluation device (80) for evaluating a tool sensor signal generated by the tool sensor (61, 62). A reference marking (R1, R2) which can be detected by the tool sensor (61, 62) is arranged within the detection range (EB1, EB2) of the tool sensor and the evaluation device (80) is configured to determine at least one correction value for the tool sensor signal depending on the reference marking (R1, R2).
