The enterprise has a number of advanced CNC machining equipment, in the production process, a large number of various types of high-value tools, tool costs accounted for a considerable proportion of production costs. With the expansion of business, increasing orders, product precision requirements, the traditional tool management is increasingly difficult to meet the demand, restricting the further development of the enterprise.

III. Difficulties faced by traditional tool management

(i) Disorganized stockpile management

1. Inaccurate inventory dataThe manual recording of tools in and out of stock often results in mistakes and omissions. For example, the actual quantity of a batch of tools received does not match the record, resulting in the inventory system shows sufficient inventory, but the production found out of stock, affecting the production schedule. According to statistics, the monthly inventory error caused by recording errors is as high as 15% - 20%.
2. Inventory backlogs and shortages coexistDue to the lack of accurate forecasts of tool consumption, purchases are often made on the basis of experience. Some of the tools are purchased in excess, and the long-term backlog occupies funds; commonly used tools are in short supply due to untimely replenishment. Enterprises have been due to a key tool out of stock, resulting in production line stalled for two days, resulting in significant economic losses. At the same time, the backlog in inventory amounted to millions of dollars.

(ii) Sloppy tool life management

1. Tool life evaluation is based on experienceTool life is mainly judged by the operator based on the machining effect and lacks scientific basis. This leads to either premature replacement of the tool, resulting in waste; or overuse, affecting the processing quality, increasing the scrap rate. Such as in the processing of aviation parts, due to excessive use of tools, scrap rate once reached 8%, far exceeding the industry standard.
2. Inability to monitor tool status in real timeDuring the production process, it is not possible to grasp the tool wear and other status information in real time. Only when processing problems occur, only to find that the tool has been damaged, can not be prevented in advance, affecting the production continuity.

(iii) Inefficient tool finding and retrieval

1. Irregular tool storageKnives are placed randomly on ordinary shelves without clear classification and positioning markings. It is time-consuming and laborious for workers to search for tools, and it takes an average of 15-20 minutes to search for a tool, which reduces work efficiency.
2. Cumbersome access processThe receipt of tools requires a paper application form, which is cumbersome and subject to multiple levels of approval. The approval process is often delayed, further affecting productivity.

Precision Inventory ManagementIntelligent tool cabinet records real-time information of tools in and out of storage, automatically updates inventory data, and improves inventory accuracy to over 99%. By integrating with the production management system, it realizes intelligent inventory warning according to the production plan and historical data of tool consumption. When the inventory is lower than the set lower limit, the system automatically reminds the purchasing department to replenish the stock to avoid out-of-stock; at the same time, the backlog of tools is found in time, which is convenient for the management personnel to deal with. After implementation, the inventory backlog was reduced by 40%, about 1.6 million yuan.
2. Optimization of purchasing plansBased on accurate inventory data and tool consumption forecasts, the purchasing department develops more rational purchasing plans. Reduce unnecessary emergency purchases and lower purchasing costs. At the same time, by negotiating with suppliers, we utilize accurate demand information to obtain more favorable purchase prices and payment terms.

(ii) Reduction of tool waste

1. Scientific tool life managementSmart tool cabinets combine sensor technology and data analysis software to monitor tool usage in real time and accurately calculate tool life. Based on the tool wear model and machining parameters, the remaining tool life is predicted. When the tool approaches the service life, the system reminds the operator to replace it, avoiding overuse that leads to tool damage and reduced machining quality. The average tool life has been extended by 25%, which reduces the frequency of tool purchasing and saves about 800,000 yuan of tool purchasing cost every year.
2. Tool recycling and reuseFor tools that have reached the end of their service life but still have some value, the intelligent tool cabinet system records their status. Enterprises can recycle these tools, such as resharpening and reusing them again. Through reasonable tool recycling and reuse, tool costs are further reduced, saving about 200,000 yuan per year.
