Description

Cutter identification device and identification method Technical Field The invention belongs to the technical field of laser identification, and particularly relates to a cutter identification device and an identification method. Background In order to more efficiently use and manage the numerical control tool, the numerical control tool management system inquires and monitors the preparation of the tool, the state of the tool, the working condition and the like in the workpiece processing process in real time so as to realize the intelligent management of workshops. Automatic identification of the cutter often uses a two-dimensional bar code as an information carrier to realize intelligent management, and automatic identification of the cutter also becomes an important link of intelligent manufacturing.
