The invention relates to an insert holder for a tool for turning a machine tool, comprising an insert holder body (2), the head (22) of which is intended to receive a cutting insert (3), characterized in that at least two measurement recesses (4, 5) are provided in the insert holder body (2) on the side of the head (22), said measurement recesses (4, 5) being arranged symmetrically relative to the neutral fiber (6) of the insert holder body (2) and centered on the neutral fiber (6). The measurement recesses (4, 5) have, respectively, a planar bottom (41, 51) that is parallel to the direction (Y) of the component of the tangential cutting force of the insert holder to be measured, and parallel to the longitudinal direction (X, Z) of the insert holder body (2). The insert holder also comprises at least one first strain gauge (71, 72, 73, 74) configured such as to measure the change in shape of the planar bottom (41, 51) of at least one of the measurement recesses (4, 5).
An insert holder for a machine tool turning tool including an insert holder body a head of which is intended to receive a cutting insert, characterized in that at least two measurement cavities are formed in the insert holder body at the head end, said measurement cavities being symmetrically arranged relative to a neutral fiber of the insert holder body and centered on the neutral fiber, each of the measurement cavities having a respective flat bottom parallel to a direction of the component of the tangential cutting force of the insert holder to be measured and parallel to a longitudinal direction of the insert holder body, the insert holder further including at least one first strain gage configured to measure the shear deformation of the flat bottom of at least one of the two measurement cavities.
