The present invention is directed to a system for determining the structural characteristics of a machine tool. The system comprises an excitation device configured to induce a dynamic excitation in a tool of the machine tool, a preloading device configured to generate a static force on the tool, and a sensing device for acquiring a set of data based on which the structural characteristics of the tool can be determined.

A smart cutting tool system for use in precision cutting, comprising a cutting insert (1), an upper cutter arbor (2), a lower cutter arbor (3), a first pressure sensor (4), a second pressure sensor (5), a signal processing module (6), a Bluetooth transmission module (7), and a power supply (8), wherein the cutting insert (1) is fixed to a front end of the upper cutter arbor (2), the cutting insert (1) is provided at its rear end with a microgroove, in which the first pressure sensor (4) and the second pressure sensor (5) are inserted. The cutting tool system solves the problem of mutual coupling of various cutting forces, and has higher sensitivity.

The invention relates to a method for shaping a periodic structure, in particular a toothing on a workpiece, wherein a lifting mechanism lifts the shaping tool, within the working stroke, off of the workpiece for the return stroke after a machining operation, characterized by a rotational angular region of the lifting cam functionally assigned to a circumferential cam profile region of a lifting cam, the same driven to rotate by a motor, of the lifting mechanism, which circumferential cam profile region determines the engagement distance between the shaping tool and the workpiece in a working stroke portion of a stroke cycle, wherein the rotational angular region of the lifting cam is passed through a further timealbeit in the opposite direction of rotationduring the same stroke cycle.
