Method for identifying power tools and their events and / or states

The present invention provides a rotatable tool 1 formed as a saw blade or milling cutter， comprising a sensor device 2 for detecting a mechanical vector 3 and a control device 4 communicatively connected to such sensor device 2. Power tool 10; 20; 30; 40; 50; 60， wherein the mechanical vector 3 comprises force， acceleration， speed， deflection， deformation and / or mechanical stress， Depending on the force coming from the tool 1， the control device depends on the direction and / or the direction change of the mechanical vector 3 detected by the sensor device 2; 40; 50; 60). The invention relates to an electric tool (10; 20; 30; 40; 0; 60) with a rotatable tool (1) formed as a saw blade or milling cutter， comprising a sensor device (2) for detecting a mechanical vector (3)， wherein the mechanical vector (3) comprises a force， an acceleration， a velocity， a deflection， a deformation and/or a mechanical stress and the mechanical vector (3) depends on a force coming from the tool (1)， and a control device (4) coupled to the sensor device (2) for communication， which control device is designed to identify an event and/or a state of the electric tool (10; 20; 30; 40; 0; 60) in accordance with a direction and/or change in direction of the mechanical vector (3) detected by the sensor device (2). The invention relates to an electric tool (10; 20; 30; 40; 0; 60) with a rotatable tool (1) formed as a saw blade or milling cutter， comprising a sensor device (2) for detecting a mechanical vector (3)， wherein the mechanical vector (3) comprises a force， an acceleration， a velocity， a deflection， a deformation and/or a mechanical stress and the mechanical vector (3) depends on a force coming from the tool (1)， and a control device (4) coupled to the sensor device (2) for communication， which control device is designed to identify an event and/or a state of the electric tool (10; 20; 30; 40; 0; 60) in accordance with a direction and/or change in direction of the mechanical vector (3) detected by the sensor device (2).
