Problems solved by technology

[0003] However, at present, the tool identification management of CNC machine tools still mainly relies on manual / barcode methods, which are inefficient and have a high error rate. A single tool change error will seriously affect the efficiency and even lead to serious consequences, especially in the current high-speed cutting and automated production lines that are widely used. Processing
In addition, the traditional tool management is inefficient, the tool preparation plan is disconnected from the production plan, and the tool inventory cost is high; the tool data is not transparent, and the management cannot grasp the tool usage

Abstract

The invention discloses a tool automatic identification system of a numerical control machining center based on RFID, which comprises an RFID tool library, a tool automatic identification unit, a toolmanagement unit and an RFID electronic tag. The invention also discloses a tool automatic identification method of a numerical control machining center based on RFID. The system and the method have the advantages that the management quantity of the cutter is increased, the misuse rate of the cutter is reduced, and the production cost of the enterprise is reduced. The system and the method have the function of tool traceability, storing the historical running track and using record of the tool in the database, sharing the data of the tool, comprehending the use of the tool omni-directionally,and facilitating the management of the enterprise; the tool management unit can realize RFID automatic tool identification, tool emergency alarm, planning the shortest tool change path, tool information storage, a traceability function, and through the analysis of tool movement path and tool information, real-time grasp tool wear and use, and predict tool life.

Description

technical field [0001] The invention relates to the technical field of tool management, in particular to an RFID-based automatic tool recognition system and method for a CNC machining center. Background technique [0002] With the proposal of "Made in China 2050", intelligent manufacturing will become the main direction of China's manufacturing industry in the future. The basic conditions for the implementation of intelligent manufacturing are "digitalization" and "networking". "Automation" is not a necessary condition for the implementation of intelligent manufacturing, but the automation of key links, such as the automation of data collection, will greatly facilitate the implementation of intelligent manufacturing. In addition, as an important part of the intelligent manufacturing system, the importance of intelligent equipment is self-evident. As an important branch of current intelligent equipment, CNC machine tools have strict requirements for the identification and mon...
