Embodiment 1

[0038] Embodiment 1: The numerical control machining center used in this embodiment is a certain turning-milling composite numerical control machining center currently being developed by Shenyang Machine Tool Group, which will use a Siemens 840D numerical control system. The tool magazine of the machining center is a chain tool magazine with an automatic tool change position. The RFID read-write antenna can be installed at the automatic tool change position to facilitate the update of tool life data during tool exchange, such as image 3 Shown.

[0039] The RFID reader is placed in a position with ample space at the rear of the machining center, and is connected to the CNC system through the RS232 interface. The machining center uses Sandvik's Coromant Caputo modular combination tool. The RFID chip can be installed in the gap of the tool change holding slot on the side of the connection pair. Sandvik can customize the connection pair with the chip installation position reserved a...

Abstract

The invention belongs to the technical field of machine tools and particularly relates to an RFID (Radio Frequency Identification Device) technology-based dynamic tool management method of a Siemens 840D numerical control system. Through research on an RFID automatic identification technology and integration with a numerical control system, a tool in a machining center is automatically identified. An RFID reader-writer selected by the invention is a BIS-C-600 type reader-writer produced by Germany BALLUFF company, an automatic tool identification technology is integrated in a numerical control system, tool information is automatically identified and tool key data is read and input to the numerical control system of the machining center, and thus the accuracy and efficiency of tool information entry are effectively improved; and life monitoring data in the numerical control system is written an RFID chip, thus a tool which is discarded or approaches the life limit is effectively prevented from being misused, and the risks that the machining quality of products is reduced and even the production safety accidents are caused are avoided. The firm foundation is laid for further realizing the tool network-based management of the whole workshop.

Description

Technical field [0001] The technical field of machine tools to which the present invention belongs specifically relates to an RFID-based ( Radio Frequency IDentification ) Technical Siemens 840D CNC system dynamic tool management method. Background technique [0002] It is known that the tool management functions of Siemens 840D CNC system include preset basic tool management functions and optional advanced tool management functions. Optional advanced tool management functions include tool monitoring and tool magazine management. There are 3 types of tool monitoring functions to choose from: monitoring of the number of workpieces to be cut, monitoring of tool life (cutting time) and monitoring of tool wear. The tool magazine management function refers to the optimized management of the tool magazine positions. The main contents include: tool loading, tool unloading, tool positioning, tool search, tool position search, and selection of search strategies when changing tools. [00...
