1. A system for estimating a state of wear of a cutting tool mounted on a machine tool, the system comprising:
an acquisition module configured to acquire, for any machining sequence of a plurality of sequences within a service life of the cutting tool, at least one operating signal specific to the cutting tool during at least one introduction interaction during which the cutting tool is introduced into a material to be machined or withdrawal interaction during which the cutting tool is withdrawn from the material, and
a microprocessor configured to generate, on a basis of the at least one operating signal corresponding only to the at least one introduction interaction or withdrawal interaction of the machining sequence, a wear signature of wear of the cutting tool and to determine the state of wear of the cutting tool within the service life of the cutting tool according to a comparison of the wear signature to a predetermined wear model.
