Tool Management in Flexible Manufacturing System and Online Testing Technology – Tools – Hardware Industry
Concern Hardware & Electrical Industry 2008 Top Ten contest, click to enter>>>>
In flexible manufacturing system, more varieties of processed parts, spare parts processing complex, and the process highly concentrated, need Tools Type, size, quantity is a lot. With the change of the processed parts and tool wear, damage, requires a mandatory tool change and random tool change time. System is running, the tool frequently between the various machine tools, machine tools and tool storage exchange between the tool flow of the transport, management and monitoring is very complicated. Therefore, the need for a sophisticated, practical and functional tool management system to achieve flexible manufacturing system, scheduling tools, storage and information management tasks.
1 tool management system should have performance
Tool management system should have performance: First, a huge number of management tools, usually several hundred to several thousand to the cutting tool; 2 delivery is high degree of automation tools, high performance, intelligent mobile robot as a tool transmission Tool ; Third is automatic, accurate information gathering tool; Fourth, the tool with large databases to achieve static and dynamic scheduling and optimization of management; 5 is automatic line detection tool life and tool wear, breakage management, and can realize online tool change function. To this end, the key components to a flexible manufacturing system, tool management system with an example.
2 the composition of tool management system
VB6.0 programming of the system software as a development platform, from six blocks and five external memory files.
2.1 blocks 2.1.1 Login module of the system to achieve the protection measures to prevent unauthorized users access to systems to ensure data and system operation security.
2.1.2 system to achieve operational control module of the system initialization, to complete the on-line tool management from the stop control of the various modules, tasks, and interface queue management, confirmed the central processing center Tool and Tool information.
2.1.3 offline tool management module to achieve the management tool libraries, tool needs analysis, planning tool assembly, tool grinding and pre-tune the code generation tool, paste and information input, the tool components management, build tools to buy inventory in a timely manner to provide the necessary tools to the line.
2.1.4 online tool management module within the flexible manufacturing system management tool activities to ensure the processing center at the right time to get the right tool to finish the machining center tools in the demand and supply, the use of appropriate strategies to achieve tool rational choice, scheduling and delivery of orders issued tools and tool remaining life calculations.
2.1.5 system information management module of the completion of missing knife checks, tool storage management (including the new tool storage and automatic online returning from a flexible tool storage), a database management tool, wear, damage and management tool database management.
2.1.6 Status Monitoring module of the system to achieve system tools, equipment failure of the monitoring and management system for the real-time management tool to provide the necessary information about the status of resources. This six block the main components of the system, which according to some logical order call each other, the system has improved, reasonable tool management functions, while the structure is independent of the subroutine modules, subroutines and data transmission between the adoption of interrelated.
2.2 external database file 2.2.1 Tool file containing all the tools of the main parameters, the parameters of each one as a Tool record.
2.2.2 machine file Store the main parameters of machine tool, a model of the machine parameters as a record.
2.2.3 Process data files
Storage and processing of various data related to the process, a data processing method as a record. Paper cutting condition factor
2.2.4 Store a variety of factors determine the cutting conditions.
2.2.5 worn, damaged paper cutter
Storage wear, tool breakage main parameters, the parameters of each one as a Tool record.
