Abstract
A cutting tool, a turning machine including the cutting tool, and an associated method are provided. The cutting tool includes a tool bar extending along an axis, a cutting head located at the tool bar, and at least one sensor integrated with the tool bar or the cutting head. A rotational orientation of the cutting tool with respect to the axis is estimated based on output provided by the at least one sensor. In at least some embodiments, the at least one sensor includes accelerometers configured to measure acceleration in at least two directions.
Claims12
A cutting tool for use in turning, the cutting tool comprising:
- a tool bar extending along an axis;
- a cutting head located at the tool bar;
- and
- at least one sensor integrated with the tool bar or the cutting head, wherein the at least one sensor is arranged to, and is of a type to, provide an output enabling estimation of a rotational orientation of the cutting tool with respect to the axis, and wherein the at least one sensor comprises an accelerometer configured to measure acceleration in at least two directions.
A method comprising:
- providing a cutting tool for use in turning, the cutting tool comprising a tool bar extending along an axis, a cutting head located at the tool bar, and at least one sensor integrated with the tool bar or the cutting head;
- providing output by the at least one sensor;
- and
- estimating, based on the output provided by the at least one sensor, a rotational orientation of the cutting tool with respect to the axis, wherein the at least one sensor comprises an accelerometer, and wherein providing output by the at least one sensor includes measuring acceleration in at least two directions.
