Kind Code:
A1
Abstract:
This cutting tool is provided with a shank that has a cutting edge or to which a cutting edge can be mounted and a sensor that is installed on the surface of the shank, wherein: the sensor is a shear strain sensor that can measure the shear strain in the shank; and a sensor distance D of the shear strain sensor fulfils Expression (1) when the shank height is referred to as W, the distance between the shank center at the installed position and the reference point of the cutting edge in a first direction, which is a direction parallel to the bottom surface of the shank and perpendicular to the shank axis, is referred to as distance dx, the distance between the shank center at the installed position and the reference point in a second direction, which is a direction perpendicular to the bottom surface of the shank, is referred to as distance dy, the distance between the installed position and the reference point in a third direction, which is a direction parallel to the axis, is referred to as sensor distance D, and the larger distance among the distance dx and the distance dy, if the distance dx and the distance dy are mutually different, is referred to as maxdxy, or the distance dx and the distance dy, if the distance dx equals the distance dy, are referred to as maxdxy. Expression (1): D < 0.74W+2.09maxdxy
