Document Type and Number:
WIPO Patent Application WO/2022/123740
Kind Code:
A1
Abstract:
This cutting tool comprises a shaft part extending from a first end section to a second end section along a rotational axis, and a sensor unit disposed so as to surround one long-axis-direction portion of the shaft part. The cutting tool rotates about the rotational axis of the shaft part, thereby cutting a workpiece. The sensor unit includes a sensor module, and a case that accommodates the sensor module. The sensor module includes: a sensor that detects a physical quantity pertaining to the shaft part; a substrate that is electrically connected to the sensor; and a wireless communication unit that is electrically connected to the substrate and that transmits, to the outside, signals including information about the physical quantity detected by the sensor. The case includes a retaining part that retains the sensor module.
