II. Background of the Company in the Case Study

[Company Name] is a company specializing in the manufacture of precision mechanical components, primarily providing customized parts for industries such as aerospace and automotive. The company owns multiple advanced CNC machining centers and relies heavily on a wide variety of high-value cutting tools during the production process; tooling costs account for a significant portion of production expenses. As the business expands, order volumes increase, and product precision requirements rise, traditional tool management methods are becoming increasingly inadequate to meet these demands, hindering the company’s further growth.

III. Challenges Faced in Traditional Cutting Tool Management

(1) Disorganized Inventory Management

1. Inaccurate inventory dataManual recording of cutting tool entries and exits often results in errors or omissions. For example, if the actual quantity of cutting tools issued for a particular batch does not match the recorded amount, the inventory system may show sufficient stock, but a shortage is discovered during production, which affects production schedules. According to statistics, inventory discrepancies caused by recording errors amount to as much as 15% – 20% each month.
2. Excess Inventory and Shortages CoexistDue to the lack of accurate forecasts for tool consumption, purchasing decisions are often made based on experience. In some cases, companies purchase too many tools, resulting in long-term inventory buildup that ties up capital; meanwhile, commonly used tools run short due to untimely restocking. On one occasion, a shortage of a critical tool caused a production line to come to a standstill for two days, resulting in significant financial losses. At the same time, capital tied up in excess inventory amounted to several million yuan.

(2) Haphazard management of tool life

1. Tool life assessment is based on experienceTool life is primarily determined by operators based on machining results, lacking a scientific basis. This leads to tools either being replaced prematurely, resulting in waste, or being overused, which affects machining quality and increases the scrap rate. For example, when machining aerospace components, the scrap rate once reached 8% due to overuse of tools, far exceeding industry standards.
2. Unable to monitor tool status in real timeDuring the production process, it is not possible to monitor status information—such as tool wear—in real time. Tool damage is only discovered when machining problems arise, making it impossible to take preventive measures in advance and thereby affecting production continuity.

(3) Low Efficiency in Locating and Retrieving Cutting Tools

1. Cutting tools are stored haphazardlyThe cutting tools are randomly placed on standard shelves without clear classification or location labels. It takes workers a long time and a lot of effort to find the tools; on average, it takes 15–20 minutes each time, which reduces work efficiency.
2. The process for obtaining it is cumbersomeTo obtain cutting tools, employees must fill out a paper application form, which then undergoes a multi-level approval process—a cumbersome procedure. Delays frequently occur during the approval process, further impacting production efficiency.
