At present, there are different management modes and methods for tools and their management in machinery manufacturing enterprises at home and abroad, mainly including the following categories:

1. Traditional models

The traditional mode of cutting tool management lacks the complete concept of tool management, and the business related to tool procurement, inventory, adjustment, grinding, repair, processing problem solving, tool optimization, cost control and so on are managed by different departments within the enterprise. Slightly larger machinery processing plants often have a tool department or tool workshop, but its function is also mainly tool grinding or tool repair and tool library or tool library management; Product machining workshop is equipped with tool engineer or technician, its task is mainly to solve the production site encountered with various kinds of processing problems related to the tool, at the same time need to be responsible for the minimum inventory setting of the tool, need to timely put forward the tool purchase application; After a series of approval procedures and procurement process, the procurement department to purchase; The production workshop is responsible for the use and adjustment of the tool, while the process or technical department is responsible for the tool optimization and improvement. This is often the problem is, the efficiency is low, the purchasing cycle is long, the cutting tool cost is high, in order to prevent the procurement procedures, long cycle and more on the abnormal consumption occurs supply of tools don't lead to serious crisis, production line stop line has to a large increase in the minimum inventory Settings, tool inventory increase greatly, takes up a lot of money, A factory producing hundreds of thousands of engines, its tool inventory may reach tens of millions of yuan, the financial cost is heavy. At the same time, but also pay attention to the traditional model of tool consumption cost calculated, often can not really reflect the actual cost of tool consumption, there may be a lot of tools by some departments to bear the human, material and financial costs are not counted, some problems in management may be covered up.

2. Outsourcing management mode

With the increasingly fierce market competition, in order to respond quickly to market competition, improve efficiency, reduce manufacturing costs and develop and maintain competitive advantages, it is required to reanalyze the value-added chain of the combined industry, carry out integrated management of all aspects involved in the tool, and reintegrate related business processes. By a unified department under centralized manage, in turn, can utilize social resources, the tool management the need a variety of expertise and resources to support outsourcing as a supportive work, realize the optimal allocation of resources, access to differentiated competitive advantage, and strict cost control, in order to obtain higher efficiency, higher quality, lower cost and maximum return on investment, This emerged cutting tool outsourcing management this management mode.

Tool outsourcing management first appeared in North American automobile manufacturing enterprises, the concept and practice of tool outsourcing management in the mid-1990s gradually spread to Europe, South America, and then spread to Asia and Oceania, professional companies specializing in tool management, such as Austria's TCM company, THE United States FSS company, etc. General motors and ford motor company many factories are applied the outsourcing management tool, but the factory application tool outsourcing management level is not the same, some factories have realized from the cutting tool procurement, inventory, adjustment, grinding, on-site technical support and problem solving and tool optimization and cost control of all the work related to the cutting tool management outsourcing, The economic settlement with outsourcing suppliers of tool management is also calculated according to the cost of tool required by a single product according to the output, which is not only conducive to management but also facilitate the comparison and analysis of product tool cost; But there are also many factories is only the tool grinding and tool supply, inventory management and other outsourcing work out, and the tool optimization and improvement and other technical work is still in their own hands, but usually for new factories and new projects pay more attention to high-level tool outsourcing management.

With the deepening of China's reform and opening up and the establishment of many joint ventures in China, the concept of tool management and its outsourcing management mode has also appeared in China. Shanghai GM has planned and adopted tool outsourcing management from the early stage of construction. Since 2002, TCM China has for the first time undertaken the tool management task of Shanghai GM powertrain plant in the way of the tool cost per workpiece processing. Subsequently, German LVLVG undertook the tool management task of Volkswagen Transmission (Shanghai) Co., LTD. Quite a few factories in China are considering or have started to adopt this new tool management mode. The concept and innovation of cutting tool management are also developing deeply.

3. Toyota Model

Japan's Toyota Motor Company was once an advocate of lean production, and it also has its own unique approach to tool management. Toyota to carry on the unification of the centralized management, tool management in the management with a special tool management institution, and is equipped with central tool library, for some common cutting tool and usage of bedding face is wide standard factory knives and knife is also unified purchase and order pull cutting tool suppliers, one of the important characteristics is a lot of cutting tools for library work shall be conducted by the supplier, The tool supplier responds immediately to the tool orders received and provides technical support and service to the tool site. Toyota tool management institutions at the same time in the middle of the coordination and guidance to each subsidiary tool sourcing, each unit to negotiate with suppliers in the price of tools and cutting tools price information gained by the management authority for the cutting tool is acquired and useful guidance, discount can be Shared by other subsidiaries acquired, This ensures that all units in the group are getting the best price, and the overall tool cost is greatly reduced by transferring much of the tool inventory work to suppliers, reducing the tool inventory and working capital. Some Japanese automobile manufacturing companies have also adopted (or partially adopted) this tool management model.
