Abstract
A method for machining a cutting tool (1, 21) and a machining device (50) for carrying out the method are proposed. The cutting tool (1, 21) has a cutting tool body (2, 22) and a cutting insert (3, 4, 5, 23) attached to the cutting tool body (2, 22) and having at least one cutting edge (10, 30). A three-dimensional surface of the cutting tool (1, 21) is defined. From this three-dimensional surface, cutting edge-defining surfaces (11a, 12a, 31a, 32a) of the cutting insert (3, 4, 5, 23) are identified. The cutting edge-defining surfaces (11a, 12a, 31a, 32a) form the surfaces of the cutting insert (3, 4, 5, 23) and are arranged adjacent to the cutting insert (3, 4, 5, 23) of the cutting insert (3, 4, 5, 23). The processing device (50) is controlled based on the cutting edge defining surfaces (11 a, 12 a, 31 a, 32 a) to intentionally remove material at the cutting insert (3, 4, 5, 23), and collision between the cutting tool and the material removal device (56) of the processing device (50) is avoided.
