Abstract
Tool for machining a workpiece, comprising a cutting insert having at least one cutting edge, a cutting insert holder comprising a cutting insert receptacle for receiving the cutting insert, a clamping element acting as a clamping wedge, which can be fastened in the cutting insert receptacle for clamping the cutting insert in the cutting insert holder, a fastening element for fastening the clamping element in the cutting insert holder and simultaneously clamping the cutting insert in the cutting insert holder, and a sensor configured to generate a measurement signal that is dependent on a force acting on the cutting insert, wherein the clamping element comprises a recess in which the sensor is arranged.
Claims17
A tool configured to machine a workpiece, comprising:
- a cutting insert having at least one cutting edge;
- a cutting insert holder comprising a cutting insert receptacle configured to receive the cutting insert;
- a clamping element configured to be fastened in the cutting insert receptacle and configured to clamp the cutting insert in the cutting insert receptacle between the clamping element and the cutting insert holder;
- a fastening element configured to fasten the clamping element in the cutting insert holder and thereby clamp the cutting insert in the cutting insert receptacle;
- and
- a sensor configured to generate a measurement signal that is dependent on a force acting on the cutting insert;
- wherein the clamping element comprises a recess in which the sensor is arranged, and
- wherein the cutting insert and the sensor are arranged at opposite sides of the clamping element, with a portion of the clamping element being interposed between the cutting insert and the sensor.
A machine tool comprising:
- a tool, said tool comprising:
- a cutting insert having at least one cutting edge;
- a cutting insert holder comprising a cutting insert receptacle configured to receive the cutting insert;
- a clamping element configured to be fastened in the cutting insert receptacle and configured to clamp the cutting insert in the cutting insert receptacle between the clamping element and the cutting insert holder;
- a fastening element configured to fasten the clamping element in the cutting insert holder and thereby clamp the cutting insert in the cutting insert receptacle;
- and
- a sensor configured to generate a measurement signal that is dependent on a force acting on the cutting insert, wherein the clamping element comprises a recess in which the sensor is arranged, and wherein the cutting insert and the sensor are arranged at opposite sides of the clamping element, with a portion of the clamping element being interposed between the cutting insert and the sensor;
- wherein the machine tool further comprises an evaluation unit connected to the sensor via a data link.
A tool configured to machine a workpiece, comprising:
- a cutting insert having at least one cutting edge;
- a cutting insert older comprising a cutting insert receptacle configured to receive the cutting insert;
- a clamping element configured to be fastened in the cutting insert receptacle and configured to clamp the cutting insert in the cutting insert receptacle between the clamping element and the cutting insert holder;
- a fastening element configured to fasten the clamping element in the cutting insert holder and thereby clamp the cutting insert in the cutting insert receptacle;
- and
- a sensor configured to generate a measurement signal that is dependent on a force acting on the cutting insert;
- wherein the clamping element comprises a recess in which the sensor is arranged, wherein the sensor is arranged between the clamping element and the cutting insert holder, and wherein the sensor is in direct contact with both the clamping element and the cutting insert holder.
A tool configured to machine a workpiece, comprising:
- a cutting insert having at least one cutting edge;
- a cutting insert, holder comprising a cutting insert, receptacle configured to receive the cutting insert;
- a clamping element configured to be fastened in the cutting insert holder and configured to clamp the cutting insert in the cutting insert holder;
- a fastening element configured to fasten the clamping element in the cutting insert holder and thereby clamp the cutting insert in the cutting insert holder;
- and
- a sensor configured to generate a measurement signal that is dependent on a force acting on the cutting insert;
- wherein the clamping element comprises a recess in which the sensor is arranged, the clamping element being surrounded on at least four sides by the cutting insert holder when the clamping element is fastened in the cutting insert holder.
