Abstract
A cutting tool for turning includes a cutting insert having a cutting edge, a holder for holding the cutting insert, a wireless communication unit for transmitting information based on a measurement result of a sensor attached to the cutting tool, an acceleration sensor installed in the holder, and a control unit for performing first control for controlling activation of the wireless communication unit based on the measurement result of the acceleration sensor.
Claims8
A cutting tool for turning, comprising:
- a cutting insert having a cutting edge;
- a holder to hold the cutting insert;
- a wireless transmitter configured to transmit information based on a measurement result of a sensor attached to the holder;
- an acceleration sensor disposed at the holder;
- and
- a processor configured to perform first control of controlling activation of the wireless transmitter, based on a measurement result of the acceleration sensor,
- wherein the acceleration sensor is configured to determine a state of the cutting tool with respect to a workpiece, and
- wherein the first control includes selectively activating the wireless transmitter based on the state of the cutting tool with respect to the workpiece.
5 more elements
A tool system comprising:
- a first cutting tool for turning;
- and
- a second cutting tool for turning,
- wherein each of the first cutting tool and the second cutting tool includes a cutting insert having a cutting edge, a holder to hold the cutting insert, a wireless transmitter configured to transmit measurement information based on a measurement result of a sensor attached to the holder, an acceleration sensor disposed at the holder, and a processor configured to perform activation control of controlling activation of the wireless transmitter, based on a measurement result of the acceleration sensor,
- wherein the processor of the first cutting tool and the processor of the second cutting tool are configured to perform the activation control at a timing of a change in the positions of the first cutting tool and the second cutting tool with respect to a workpiece, details of the activation control performed by the processor of the first cutting tool and details of the activation control performed by the processor of the second cutting tool being different from each other,
- wherein when the wireless transmitter of the first cutting tool is active, the wireless transmitter of the second cutting tool is inactive, and
- wherein when the wireless transmitter of the second cutting tool is active, the wireless transmitter of the first cutting tool is inactive.

A communication control method in a tool system including a first cutting tool for turning and a second cutting tool for turning,
- each of the first cutting tool and the second cutting tool including a cutting insert having a cutting edge, a holder to hold the cutting insert, a wireless transmitter configured to transmit information based on a measurement result of a sensor attached to the holder, an acceleration sensor disposed at the holder, and a processor configured to perform activation control of controlling activation of the wireless transmitter, based on a measurement result of the acceleration sensor, the communication control method comprising:
- acquiring, by the processor of the first cutting tool, the measurement result of the corresponding acceleration sensor;
- acquiring, by the processor of the second cutting tool, the measurement result of the corresponding acceleration sensor;
- and
- performing, by the processor of the first cutting tool and the processor of the second cutting tool, the activation control, details of the activation control performed by the processor of the first cutting tool and details of the activation control performed by the processor of the second cutting tool being different from each other,
- wherein when the wireless transmitter of the first cutting tool is active, the wireless transmitter of the second cutting tool is inactive, and
- wherein when the wireless transmitter of the second cutting tool is active, the wireless transmitter of the first cutting tool is inactive.
