Abstract
A tool received in a tool holding fixture of a tool holder includes a tool shank defining a recess and a force sensor arranged in the recess. During operation of the tool, the force sensor measures a tool force exerted by the tool shank onto the tool holder. A method for measuring a tool force by using the tool includes the steps of: arranging the force sensor between the tool shank and the tool holding fixture; clamping the force sensor by means of a clamping device of the tool holding fixture; operating the tool; and using the force sensor to measure the tool force exerted by the tool shank onto the tool holder.
Claims12
A tool comprising:
- a tool holder that includes a tool holding fixture that is configured to receive a tool shank, wherein the tool holding fixture includes a clamping device configured for clamping a tool shank and including a wedge;
- a tool shank received by the tool holding fixture;
- a recess manufactured in the tool shank;
- a force sensor arranged in the recess of the tool shank;
- wherein the clamping device is configured for exerting a pretensioning force that is equal to a clamping force exerted by the clamping device on the force sensor;
- and
- wherein the force sensor is configured to measure a tool force exerted by the tool shank onto the tool holder during operation of the tool.
