Abstract
A cutting tool includes: a cutting section having a cutting edge; a sensor provided in the cutting section; and a communication unit provided in the cutting section. The communication unit transmits, to a processing device provided outside the cutting tool, measurement information relating to measurement results of the sensor and including serial numbers corresponding to the measurement results after a timing of a start of cutting by the cutting edge.
Claims18
A cutting tool comprising:
- a cutting section having a cutting edge;
- a sensor provided in the cutting section;
- a processor;
- and
- a transmitter provided in the cutting section, wherein
- the transmitter is configured to transmit, to a processing device provided outside the cutting tool, measurement information including a measurement result of the sensor and a serial number of the measurement result measured after a start of cutting by the cutting edge,
- the processor is configured to determine the start of cutting by the cutting edge based on the measurement result that is measured in a first timing and the measurement result that is measured in a second timing directly before the first timing,
- the measurement results measured in or after the first timing are in order numbered with different serial numbers, the transmitter transmits the measurement information including the different serial numbers to the processing device based on an instruction by the processor, and
- the processor is further configured to generate the measurement result of the sensor and not transmit the measurement result to the transmitter when the cutting edge is in contact with a workpiece and to transmit the measurement result to the transmitter and not generate the measurement result when the cutting edge is not in contact with the workpiece.

A cutting tool for turning machining, used to machine a rotating workpiece, the cutting tool comprising:
- a cutting section having a cutting edge;
- a sensor provided in the cutting section;
- a processor;
- and
- a transmitter provided in the cutting section, wherein
- the transmitter is configured to transmit, to a processing device provided outside the cutting tool, measurement information including a measurement result of the sensor and a serial number of the measurement result measured after a start of cutting by the cutting edge,
- the transmitter is configured to transmit the measurement information including corresponding one or multiple ones of the measurement results to the processing device at a timing in accordance with a number of revolutions of the workpiece, and
- the processor is configured to generate the measurement result of the sensor and not transmit the measurement result to the transmitter when the cutting edge is in contact with the workpiece and to transmit the measurement result to the transmitter and not generate the measurement result when the cutting edge is not in contact with the workpiece.
