The machine tool (10) is provided with a height measuring device (95) for detecting a height (H) of the workpiece (W), wherein the height corresponds to a distance between an upper side (WO) of the workpiece which is to be penetrated by the work tool (15) and a workpiece underside (WU) of the workpiece (W) opposite the upper side of the workpiece (W).

A mobile machine tool, 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), wherein the machine tool (10) is provided with a tool sensor arrangement (61, 62) for detecting a workpiece contact region in which a work tool (15) arranged on the tool holder (14), is in contact with the workpiece (W). The tool sensor arrangement (61, 62) comprises at least two tool sensors (61, 62), the detection ranges of which (EB1, EB2) are assigned to different partial workpiece contact regions (WK1, WK2) of the workpiece contact region.

An example pipe cutting tool includes a plurality of actuators and a plurality of cutters. Each of the plurality of cutters is connected to at least one separate actuator of the plurality of actuators. The at least one separate actuator is configured to move the cutter between a pre-deployed and deployed position. The deployed position is beyond the pre-deployed position. The plurality of cutters may include a first and second cutter, with the at least one separate actuator connected to the second cutter moving based, at least in part, on one or more cutting conditions. An example method of cutting a pipe includes extending a first cutter to contact the pipe, cutting at least a portion of the pipe using the first cutter, detecting a cutting condition, extending a second cutter based, at least in part, on the cutting condition, and resuming the cutting using the second cutter.

A method for controlling a device system (10) during the cutting of a workpiece (18) along a cutting line (43) up to a first end point (E.sub.1) using a saw head (12) that can be moved on a guide rail (11) along an advancing direction (26), whereby the saw head (12) is arranged on the guide rail (11) in a starting position (X.sub.0), and a first partial length (L.sub.1) extending from the starting position (X.sub.0) to the first end point (E.sub.1) of the cutting line (43) is entered.
