In the flexible manufacturing system, there are many varieties of parts to be processed, the parts processing technology is complicated, and the process is highly concentrated, and the types, specifications, and quantities of tools required are many. With the change of the machined parts and the wear and tear of the tool, it is necessary to change the tool and the random tool change. During the operation of the system, the tools are frequently exchanged between the machine tools and between the machine tool and the tool magazine. The transportation, management and monitoring of the tool flow are very complicated. Therefore, there is a need for an advanced, practical, and fully functional tool management system to enable tasks such as scheduling, storage, and information management in flexible manufacturing systems.

1 tool management system should have the performance

The performance of the tool management system: First, the management of a large number of tools, usually hundreds to thousands of tools; Second, the high degree of automation of tool delivery, high-performance, intelligent robots as a tool for tool flow; The third is to automatically and accurately collect tool information; the fourth is to realize the tool scheduling and dynamic and static optimization management by means of large-scale database; the fifth is to automatically detect tool life and tool wear and damage management online, and realize online tool change function. To this end, the tool management system in a flexible machining system of a certain key component is taken as an example for description.

2 the composition of the tool management system

The system uses VB6.0 programming system software as the development platform, consisting of 6 program blocks and 5 external files.

2.1 program block

2.1.1 The user login module mainly implements protection measures for the system to prevent illegal users from entering the system and ensuring the security of system data and system operation.

2.1.2 System operation control module mainly realizes the initialization of the system to complete the start-stop control, task queuing and interface management of various modules of online tool management, and confirm the information of the machining center tool magazine and the central tool magazine.

2.1.3 tool offline management module mainly realizes tool library management, tool requirement analysis, tool assembly planning, tool sharpening and presetting, tool code generation, paste and information input, tool component management, tool purchase Checklist to provide the required tools in line in time.

2.1.4 Tool online management module mainly realizes the management of tool activities in the flexible manufacturing system, ensures that the machining center gets the correct tool at the right time, completes the demand and supply of the tool in the machining center, and uses appropriate strategies to achieve reasonable selection of the tool. , scheduling and release of tool transfer instructions and calculation of tool remaining life.

2.1.5 System Information Management Module mainly completes the lack of knife inspection, tool storage management (including new tool storage and tool return from flexible automatic line), tool outbound management, wear and tear tool management and database management.

2.1.6 System status monitoring module mainly realizes the monitoring of tool and equipment faults in the system and provides the necessary resource status information for real-time management of the tool management system. These six blocks are the main components of the system. They are called each other in a certain logical order, so that the system has perfect and reasonable tool management functions. At the same time, it is a sub-program module with independent structure. The sub-programs pass data transmission. interconnected.

2.2 external database files

2.2.1 Tool file, the main parameters of all the tools are stored, and the parameters of each tool are taken as one record.

2.2.2 Machine documentation

The main parameters of the machine are stored, and the machine parameters of one model are taken as one record.

2.2.3 Process Data File

Stores various process-related process data, and data of one processing method as one record.

2.2.4 Cutting condition coefficient file

Store various coefficients that determine the cutting conditions.

2.2.5 worn and damaged tool files

The main parameters of the worn and damaged tool are stored, and the parameters of each tool are taken as one record.
