Title:
CUTTING TOOL AND CUTTING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/113750
Kind Code:
A1
Abstract:
This cutting tool comprises: a shank which has a cutting edge, or to which a cutting edge can be attached; and a plurality of sensors mounted on a surface of the shank. At least two of the plurality of sensors are shear strain sensors capable of measuring the shear strain of the shank. When a shank height of the shank is W, a distance between the center of the shank at a mounting position of the sensor and a reference point of the cutting edge in a first direction which is a direction that is parallel to a bottom surface of the shank and orthogonal to an axis of the shank is a distance dx, a distance between the center of the shank at the mounting position and the reference point in a second direction which is a direction that is orthogonal to the bottom surface of the shank is a distance dy, a distance between the mounting position and the reference point in a third direction which is a direction that is parallel to the axis is a sensor distance D, and the smaller of the distance dx and the distance dy in the case that the distance dx and the distance dy are different values is mindxy, the sensor distance D of the two shear strain sensors satisfies formula (A): D<0.74W+2.09mindxy. Among a first load which is a load in the first direction, a second load which is a load in the second direction, and a third load which is a load in the third direction, one of the two shear strain sensors has a maximum sensitivity with respect to the second load, and the other of the two shear strain sensors has a maximum sensitivity with respect to the first load.
