Tool management long way to go

The same time as the above-

Tool management is the most fundamental function is to reduce the cost of tools have to reduce the cost of enterprises to make system. Enterprise tool costs can be divided into two parts: ① the tool has a direct cost, that is, the cost of selling tools. This part of the cost of the enterprise due to the details of the different, ordinary parts of the system cost of 2% to 5%. On this part of the tool costs, the current divergent views are: do not unilaterally seek to reduce this part of the cost of the tool, because it is very low to reduce the cost of manufacturing is very infinite, and actively use high-performance tools to improve processing efficiency, This was more effective. (2) The expenses incurred by the enterprise for the use and management of the tool, including the cost of selling, storing, assembling, commissioning, re-grinding and recoating the tool, have resulted in expenses such as salaries, depreciation and equipment depreciation. Money and unreasonable use of the formation of waste and so on. According to the international mold and metal plastic industry supplier association survey shows that this part of the cost of production costs accounted for 15% or even 30%, far more than the direct cost of the tool.

"Through the superstitious tool management, can reduce the tool inventory, reduce the personnel, capital, plant, equipment occupied, reduce the knife error, which significantly reduce the direct costs of the tool to reduce production costs have great potential." International Mold And metal plastic industry suppliers Association Secretary-General Luo Baihui that tool management can reduce the type of tool up to 20%, reducing the number of knapsets were more than 30%.

In the above tool management based on the basic functions, the ancient tool management also has to optimize the processing process, improve the processing efficiency of advanced features. In the design and processing process, the tool management software can be processed according to the workpiece material, the use of machine tools and other processing conditions to choose a better tool and better cutting parameters, to achieve improved cutting efficiency, to ensure the quality of processing results. In addition, the timely and correct for the knife can also be reduced by the number of CNC machine downtime to be time to do, to mention the high cost of CNC machine tools (according to the different circumstances of enterprises can improve the utilization of CNC machine tools 5% to 50%), The same can bring direct economic benefits for the enterprise.

According to the user tool management system in two different stages of different needs, the current market emerged a variety of tool management form. These forms can be divided into two major categories: one is the use of the workshop for the object to the logistics management-based tool management system. This form can be divided according to the number of service content and the level of different levels: the primary management system is only served as a tool to sell and inventory management; higher and other management system also served as the production site problems and tool improvement; Do not have the management system is the use of all-inclusive situation, by the tool management company set up outside the enterprise resident agencies, a comprehensive management of the production site were cutting tools, and the tool to stop optimization. On the first two management levels, on weekdays by the tool supplier to set the tool in the workshop automatic warehouse method or the workshop was to stop the management of the tool library. This tool management system in addition to the management of the machine operator to get the tool, the settlement can also be through the collection and management of the warehouse in the inventory, real-time replenishment of tools, and provide analysis of workers using the tool information, can be improved Tool usage, lower tool inventory and administrative costs. At present, such systems are mainly provided by tool manufacturers, large tool distributors or engineering software development companies, and have different advantages and disadvantages. The tool manufacturers and agents have a strong technical advantage. There are some limitations; engineering software company developed the system is more introduced the analysis, reasoning, expert knowledge and other functions in the function of complete and compatibility has a certain advantage.

Tool management system has to grow

The same time as the above-

(1) to strengthen the tool management system of professional and technical content, promotion of the correct election force, to meet the premise of the application of the tool. The correct selection of the knife is to ensure the quality and efficiency of processing on the premise, and the need to provide application technology (such as high-speed rotating tool balance and clamping technology, tool safety technology, etc.) can play sufficient tool processing performance. In addition, the tool management system should be able to reflect the industry characteristics. Machinery industry in the application of the various key industries (such as cars, molds, aerospace, power generation equipment manufacturing, etc.) in the processing technology, production volume, processed parts and other materials have their own characteristics, the tool also have different requirements, a good The tool management system should be technically reflective of the different characteristics and differences of the industry.

(2) the development of the form of factoring, the maximum limit to display tool management system potential. International mold and metal plastic industry supplier Association Secretary-General Luo Baihui that tool management outsourcing form of service-oriented manufacturing industry in line with the direction of development, but also in line with the future changes in the form of tool industry to improve the service in order to have a transition bias, so a broad development prospects The Tool management outsourcing can be divided into individual, part of the outsourcing and comprehensive outsourcing. The former is more dexterous, easy to introduce, adapt to a wide range, especially the joint tool to take the initiative in the form of warehouses, in the United States, Germany and other countries developed faster, more applications. The latter, such as Shanghai General Motors Corporation to take a comprehensive management of tooling outsourcing project, by the tool management company to replace the general company outside the tool management department of the whole operation, it is reported that its economic and technological benefits are very obvious. From the state of the whole state analysis, this outsourcing form is more suitable for a large number of assembly line production workshop, its products, processes and tools are absolutely more stable, the operation generated a large number of statistical data to help stop the super economic technology analysis. There is also a worry about the current outsourcing, that so do bad luck in the technical know-how and tool expertise accumulated.
