Description

Technical Field

[0001] The present invention relates to the technical field of tool information management, and in particular to a tool information management system and a method for applying the tool information management system. Background Art

[0002] The tool system is an important auxiliary tool in mechanical manufacturing activities. It plays a vital role in the flexibility, productivity, and precision and correctness of product manufacturing of machining centers and CNC machine tools. At the same time, in general production workshops, especially in production environments with a large number of CNC machine tools, the number of tools is huge, the components of which are also quite complex, and the information is extensive. Due to the actual needs of production, a large number of tools frequently flow and exchange between the tool library and machine tools, and between machine tools.

[0003] With the widespread adoption of CNC machining equipment across the enterprise, the number and variety of tools used with it continues to grow. This escalating inventory volume is increasingly inefficient due to traditional manual management. Tool locating, selecting, borrowing, and returning tools consume significant time. Downtime caused by tool shortages has become a production bottleneck in modern CNC workshops, hindering machining efficiency and increasing production costs. To better manage tool inventory, the development of tool management software is imperative.

[0004] Based on this, Chinese patent document CN109102235A discloses a tool life information management system and method, which includes a management center for recording tool information for each tool in the management system and calculating the total service life of all tools in the management system; a query panel from which users can query the data stored in the management center; an alarm module that issues an alarm when the total service life reaches the safety inventory value; an information reading and writing module; and an information entry module. This technical solution can uniquely number different types of tools in parallel, register all tools, and monitor their service life. It can also prepare spare tools in advance and install, adjust, and measure tools in advance to avoid untimely tool supply. It can also query the service life of all tools through the query panel and monitor the status of each tool in real time based on the number, refining inventory management, reducing inventory, automating plan submission, and effectively controlling tool costs.

[0005] However, the tool information management system and method disclosed in the prior art still have the technical problem of low management efficiency. Specifically, although the prior art can monitor the status of each tool in real time according to the number to reduce inventory and thus control the cost of the tool. However, the existing tool management method is mainly as follows: the process engineer consults the tool information according to the processing requirements, searches for tools on site and in the warehouse, and formulates a tool selection plan; the production department collects the relevant tools from the warehouse according to the plan. Due to the continuous increase in the brands, types and quantities of tools, and the gradual increase in the number of new product types, the traditional management method that relies solely on manpower is very cumbersome and backward, which easily leads to waste of human resources, long tool preparation time, low tool utilization, reduced production efficiency, and the inability to effectively monitor the use of tools. Summary of the Invention

[0006] Based on this, it is necessary to provide a tool information management system and a tool information management method to address the technical problem of how to improve the circulation and use efficiency of tools.

[0007] A tool information management system, characterized in that it includes: a tool information management module, a process management module, a distributed CNC module, a resource planning module and a manufacturing execution module; the tool information management module performs basic information maintenance, statistical information query, warehouse location management, distribution information management, tool inventory management and system management functions; the tool information management module outputs tool parameter management instructions to the process management module, and the process management module returns process procedure tool information to the tool information management module; the tool information management module and the distributed CNC module transmit tool cutting parameters to each other; the resource planning module archives the tool supplier catalog to the tool information management module, and the tool information management module outputs tool procurement plan instructions to the resource planning module; the tool information management module outputs tool borrowing flow records, tool management data statistics and tool inventory information to the manufacturing execution module respectively, and the manufacturing execution module returns personnel information, equipment information and plan information to the tool information management module respectively.

[0008] Specifically, the tool information management module divides the system users' addition, deletion, modification and query, user data permissions and menu permissions accordingly; for a workshop with more than one warehouse, different warehouse permissions are granted to the custodians corresponding to different workshops, so that the corresponding custodians can only manage the tool information of the warehouses with permissions, without interfering with or affecting each other; different menu permissions are granted to users of different departments, and the corresponding users can only operate the business processes under their own functions.

[0009] Specifically, the tool information management module is based on the enterprise local area network, and establishes data interfaces and business interfaces between the tool management module and the process management module, the manufacturing execution module, the distributed CNC module and the resource planning module, so as to realize the integration of tool management with upstream and downstream production links and internal workshop business in the business of tool selection, parameter transmission, logistics distribution, cost statistics, loss monitoring and inventory warning.

[0010] Furthermore, a method for applying the aforementioned tool information management system includes the following steps: S1: The tools for the CNC workshop are purchased centrally by the resource planning module. After being delivered to the workshop, they are received by the custodian and stored in the main warehouse. S2: Based on the demand displayed by the manufacturing execution module, the custodian will allocate a preset number of tools to each branch warehouse and use the delivery method when the tools are borrowed; S3: When dispensing knives, workers submit a request for dispensing knives based on their production needs, specifying the delivery location and time required. The process management system automatically selects the tool list according to the process regulations, and the worker determines the details of the tools to be delivered. S4: After receiving the delivery request information, the delivery staff will borrow tools from each branch warehouse according to the tool list information. After all the tools are collected, the delivery staff will send the tools to the tool adjustment room for adjustment. During the adjustment process, the tool accessories will be shipped out of the warehouse. S5: After tool adjustment is completed, the tool is measured and the tool measurement data is filled in. The tool measurement data is then transmitted to the destination processing workshop in real time through the distributed CNC module. After the distributed CNC module returns the tool measurement data confirmation information, the delivery personnel deliver the tool to the destination processing workshop on schedule, and the worker receives and confirms the delivery. S6: When the worker finishes using the tool, he / she initiates a return request. At the same time, the distributed CNC module transmits the tool's cutting parameters and usage time back to the tool information management module. The delivery personnel then receive and confirm the information and send it to the tool setting room for disassembly before sending it to the warehouse for storage. The delivery request information is closed at this point. S7: Tools that need to be sharpened or scrapped are handled uniformly by the warehouse custodian. At the same time, the tool information management system automatically issues an inventory warning to the resource planning module based on the preset inventory warning model after summarizing the real-time information of the manufacturing execution module. The resource planning module then automatically issues a tool procurement plan.

[0011] Specifically, In the inventory warning model of step S7, the following two judgment procedures are used to determine whether the preset inventory of tool components meets the production plan: Judgment procedure 1:

[0012] Judgment procedure 2:

[0013] Among them, D j is the purchasing cycle of tool brand j, in days; P i V is the planned number of production in the ith month in the n-month production cycle, in units of units; k A is the number of tool components k processed during its life cycle, in units of units; k is the total inventory of tool component k, in units of pieces; e k is the spare reserve quantity, unit: piece; When the judgment condition of at least one of the judgment procedures 1 or 2 is met, the tool information management module automatically sends an inventory warning to the resource planning module, and the resource planning module automatically arranges tool procurement.

[0014] In summary, the present invention proposes a tool information management system and a tool management method using the aforementioned tool information management system. The tool information management system includes: a tool information management module, a process management module, a distributed numerical control module, a resource planning module and a manufacturing execution module; the tool information management module performs basic information maintenance, statistical information query, warehouse location management, distribution information management, tool inventory management and system management functions; the tool information management module outputs tool parameter management instructions to the process management module, and the process management module transmits process procedure tool information back to the tool information management module; the tool information management module and the distributed numerical control module transmit tool cutting parameters to each other; the resource planning module archives the tool supplier catalog to the The tool information management module outputs the tool procurement plan instructions to the resource planning module; the tool information management module outputs the tool borrowing flow record, tool management data statistics and tool inventory information to the manufacturing execution module respectively, and the manufacturing execution module transmits the personnel information, equipment information and plan information back to the tool information management module respectively; this tool management method adopts a database as the basis, and realizes data interaction between each module by transmitting information with the database; and comprehensively considers and analyzes inventory warnings with workshop production plans, tool service life, procurement cycles and other information to establish an accurate inventory warning model; thus, the information-based turnover model is used to improve the accuracy and convenience of tool circulation; and the inventory warning model is used to improve the efficiency of tool use. Therefore, the tool information management system of the present invention solves the technical problem of how to improve the circulation and use efficiency of tools.

[0022] Please also refer to Figures 1 to 2 The present invention provides a tool information management system, which includes: a tool information management module, a process management module, a distributed CNC module, a resource planning module and a manufacturing execution module; the tool information management module performs basic information maintenance, statistical information query, warehouse location management, distribution information management, tool inventory management and system management functions; the tool information management module outputs tool parameter management instructions to the process management module, and the process management module returns process procedure tool information to the tool information management module; the tool information management module and the distributed CNC module transmit tool cutting parameters to each other; the resource planning module archives the tool supplier catalog to the tool information management module, and the tool information management module outputs tool procurement plan instructions to the resource planning module; the tool information management module outputs tool borrowing flow records, tool management data statistics and tool inventory information to the manufacturing execution module respectively, and the manufacturing execution module returns personnel information, equipment information and plan information to the tool information management module respectively.

[0023] Specifically, the tool information management module is mainly responsible for adding, deleting, modifying and checking system users, and dividing user data permissions and menu permissions. For workshops with multiple warehouses, different custodians are given different warehouse permissions, and can only manage tool information in warehouses with permissions, without interfering with or affecting each other. Different menu permissions are given to users in different departments, and they can only operate business processes under their own functions. In addition, the tool information management module can establish data interfaces and business interfaces between the tool management module and the process management module, the manufacturing execution module, the distributed CNC module and the resource planning module based on the enterprise LAN, and realize the integration of tool management with upstream and downstream production links and internal workshop businesses in tool selection, parameter transmission, logistics distribution, cost statistics, loss monitoring and inventory warning; furthermore, a comprehensive information system integration environment covering the integration of tool application information and process information, planning information, processing information, business information, etc. can be established.

[0024] Specifically, the manufacturing execution module is the core information platform connecting the resource planning module and the workshop production equipment control layer. It realizes transparent control of the production process by real-time collection of production data, monitoring process execution, and scheduling resource optimization. Its core functions include order scheduling, quality traceability, equipment management, material tracking, performance analysis, etc., aiming to improve production efficiency, reduce losses, ensure compliance, and provide data support for corporate decision-making. It is suitable for the digital transformation needs of discrete manufacturing and process industries.

[0025] Specifically, the distributed CNC module is a centralized management module for CNC equipment based on a network architecture. It realizes program transmission, status monitoring, and data collection through real-time communication between a computer and multiple CNC machine tools. Its core functions include: 1. Program management: remote issuance, editing, and backup of processing programs; 2. Equipment networking: support for the integration and collaborative operation of heterogeneous CNC systems; 3. Production monitoring: real-time feedback on machine tool operating status, processing progress, and fault alarms; 4. Data traceability: recording processing parameters and process data to facilitate quality analysis and optimization. As a result, the distributed CNC module can improve the automation level and production efficiency of CNC workshops by eliminating the limitations of traditional single-machine transmission.

[0026] Specifically, the process management module is an information-based tool that uses computer technology to assist in developing product processing routes. By integrating product design data, such as CAD models and enterprise resource information, it automatically or semi-automatically generates documents such as process specifications, process cards, and labor quotas. Its core functions include: 1. Process design automation: Rapidly generate process routes based on rules or intelligent algorithms; 2. Resource optimization: Matching production resources such as equipment, tools, and materials; 3. Standardized management: Maintaining a process knowledge base to ensure process consistency; 4. Integrated interconnection: Connecting with the manufacturing execution module and the resource planning module to achieve multi-party data collaboration. Therefore, the process management module can improve process design efficiency and accuracy by reducing manual intervention, and is a key link in intelligent manufacturing.

[0027] Specifically, the resource planning module is an integrated information management platform that integrates core business processes such as finance, supply chain, production, sales, and human resources through a unified database, enabling real-time data sharing and collaborative optimization. Its core functions include: 1. Resource integration: connecting cross-departmental data flows to eliminate information silos; 2. Process automation: standardizing business operations such as procurement, inventory, and production; 3. Decision support: generating reports through data analysis to assist in strategic planning; and 4. Compliance control: tracking audit logs to meet industry regulations. By improving operational efficiency and resource utilization, the resource planning module can achieve digital transformation and refined management for enterprises.

[0028] Furthermore, within the tool information management module, the basic information maintenance module, or static tool information management module, includes four major functions: tool category management, tool parameter information management, borrowing quantity safety stock setting and alerts, and in-and-out type maintenance. Tool category maintenance involves more than simply categorizing tools by type; it also includes defining the specifications for each type. Inconsistent specifications provided by different suppliers can lead to confusing parameter management. Standardized specification definitions will effectively improve tool search efficiency. Setting borrowing quantities and safety stocks effectively controls inventory and tools in use, reducing tool costs. The in-and-out type management function unifies the management of tool in-and-out types involved in the process. Based on actual requirements, tool usage limits can be set for each out-and-out process type. Tools approaching their expiration date are specially marked and the borrower is alerted. Once the limit is exceeded, management will impose penalties according to management regulations. This function effectively promotes tool circulation and utilization, improving tool utilization.

[0029] Furthermore, the warehouse location management module allows for the addition and deletion of warehouse locations based on actual needs. The tool inventory management module and the delivery information management module, also known as the tool dynamic information management module, manage tool delivery and inbound / outbound operations, including sharpening and scrapping. The delivery card query and processing function allows personnel of different roles to query and process delivery cards in different states, and the card status changes accordingly with process changes. The worker query function allows workers to view their currently borrowed delivery cards and tool information lists, request returns, and request tool changes. This allows them to directly replace tools when machining the same part, eliminating the need to submit a new delivery request, streamlining the process and improving efficiency. Delivery relationship maintenance aligns delivery workers with different equipment, assigning dedicated personnel to deliver tools to each piece of equipment, ensuring timely delivery statistics. The information query module provides users with tool information flow records and regular warehouse inventory checks, allowing for statistical analysis and comparison of historical tool data.

[0030] Furthermore, in the tool information management module, backend data is stored in a relational database. Data tables are created based on the classification principles of static tool information and dynamic tool information. Each data table is assigned a unique primary key, and the data tables are interconnected through the primary key. When operating the backend database, the system's business processes minimize changes to static information data while maintaining complete records of dynamic information data.

[0031] Therefore, based on the aforementioned tool information management system, a tool information management method includes the following steps: S1: The tools for the CNC workshop are purchased centrally by the resource planning module. After being delivered to the workshop, they are received by the custodian and stored in the main warehouse. S2: Based on the demand displayed by the manufacturing execution module, the custodian will allocate a preset number of tools to each branch warehouse and use the delivery method when the tools are borrowed; S3: When dispensing knives, workers submit a request for dispensing knives based on their production needs, specifying the delivery location and time required. The process management system automatically selects the tool list according to the process regulations, and the worker determines the details of the tools to be delivered. S4: After receiving the delivery request information, the delivery staff will borrow tools from each branch warehouse according to the tool list information. After all the tools are collected, the delivery staff will send the tools to the tool adjustment room for adjustment. During the adjustment process, the tool accessories will be shipped out of the warehouse. S5: After tool adjustment is completed, the tool is measured and the tool measurement data is filled in. The tool measurement data is then transmitted to the destination processing workshop in real time through the distributed CNC module. After the distributed CNC module returns the tool measurement data confirmation information, the delivery personnel deliver the tool to the destination processing workshop on schedule, and the worker receives and confirms the delivery. S6: When the worker finishes using the tool, he / she initiates a return request. At the same time, the distributed CNC module transmits the tool's cutting parameters and usage time back to the tool information management module. The delivery personnel then receive and confirm the information and send it to the tool setting room for disassembly before sending it to the warehouse for storage. The delivery request information is closed at this point. S7: Tools that need to be sharpened or scrapped are handled uniformly by the warehouse custodian. At the same time, the tool information management system automatically issues an inventory warning to the resource planning module based on the preset inventory warning model after summarizing the real-time information of the manufacturing execution module. The resource planning module then automatically issues a tool procurement plan.

[0032] Furthermore, as consumables, cutting tools gradually wear out during use, eventually becoming scrapped. Therefore, it is crucial to rationally plan production, quickly and accurately count tool usage, and provide timely feedback and early warnings on inventory status. Inventory warnings, however, alert when the number of tools in inventory exceeds or falls below a warning range. Current tool management systems typically use a fixed redundancy method, directly setting upper and lower warning limits for a specific number of tools. This approach is inconsistent with actual business practices.

[0033] Therefore, in order to implement inventory warnings more flexibly, it is necessary to comprehensively consider and analyze inventory warnings with information such as the workshop production plan, tool life, and procurement cycle to establish an accurate inventory warning model. In actual production, since the processing object and processing parameters are fixed, the life of each tool component during use is also basically stable. Therefore, the following two judgment procedures can be used to determine whether the inventory level of a tool component meets the production plan: Judgment procedure 1:

[0034] Judgment procedure 2:

[0035] Among them, D j is the purchasing cycle of tool brand j, in days; P i is the planned production quantity for month i in the production cycle of n months, in units of units; V k A is the number of units or pieces processed by tool component k during its life cycle, with the unit corresponding to units or pieces; k is the total inventory of tool component k, in pieces; e k is the spare reserve quantity, unit is piece.

[0036] Specifically, judgment procedure one considers only the relationship between the existing production plan and total inventory. If the production plan's tool consumption plus the additional reserve exceeds the inventory, an inventory warning is issued. Judgment procedure two, on the other hand, indicates that if the production plan is shorter than the procurement cycle, the monthly average consumption rate of the existing production plan is used to predict inventory levels within the procurement cycle. If the predicted demand exceeds the inventory, an inventory warning is also issued. Therefore, taking all of these into account, when either or both of these conditions are met, the tool information management module automatically issues an inventory warning to the resource planning module, which then automatically arranges tool procurement.

[0037] To more accurately predict the relationship between production plans and tool wear requirements, we can provide the following example: A company specifies the type and quantity of part A in its actual production plan P. The production of each part is determined by the production process, which defines a production step WP. Each step requires the use of specific tools and has a theoretical tool wear. In actual production, actual tool wear is incurred during the execution of the step. Therefore, let X represent the actual average tool wear of tool t. The following functional relationship can be established between the production plan P and tool wear X: Let WP represent the production process. Assuming that each production process requires n types of tools and the number of each tool is k, then Formula 1: WP=k1*x1+k2*x2+…+kn*Xn Next, let A represent a part. Assume that each part has a process and the number of processes for each process is L. The relationship between part A and tool consumption X is expressed as follows: A =Ll*WP1+L2*WP2+…+Lm*WPm =Ll(k1*X1+k2*X2+…+kn*Xn)1+L2(k1*X1+k2*X2+…+kn*Xn)2+…+m(k1* X1+k2*X2+…+kn*Xn)m Furthermore, let P represent the company's daily production plan. Suppose each batch of production plan has w types of parts, and the number of each type of part is u. Then the relationship between the production plan P and the tool consumption X is expressed as follows: P =w1*A1+w*A2+…+wu*Au =w1(L1(k1*X1+k2*X2+…+kn*Xn)1+L2(k1*X1+k2*X2+…+kn*Xn)2+… +Lm(k1*X1+k2*X2+…+kn*Xn)m)1+w2(L1(k1*X1+k2*X2+…+kn*Xn)1 +L2(k1*X1+k2*X2+…+kn*Xn)2+…+Lm(k1*X1+k2*X2+…+kn*Xn)m)2 +…+wu(L1(k1*X1+k2*X2+…+kn*Xn)1+L2(k1*X1+k2*X2+…+kn*Xn)2+… +Lm(k1*X1+k2*X2+…+kn*Xn)m)u In the above formula, k, 1, and w are all natural numbers, so it can be concluded that there is a linear regression relationship between P and X. Once P is known, the loss X of each required tool can be calculated according to Formula 3. The tool loss table required for machining each part in the production plan needs to summarize and count the average loss, minimum loss, loss cycle, and other data of each tool in the tool list required for part production. The entire information extraction process is as follows: the part information in the production plan of the manufacturing execution module is connected to the tool parameters and production process requirements in the process management module to form a part-tool list; then, it is associated with the actual loss of each tool in the distributed CNC module, and finally a <part ID, tool type ID, production plan ID, average loss> data table is formed; in addition, according to the above process, k, w, 1 and the average consumption value of each tool can also be obtained.

[0038] In summary, the present invention proposes a tool information management system and a tool management method using the aforementioned tool information management system. The tool information management system includes: a tool information management module, a process management module, a distributed numerical control module, a resource planning module and a manufacturing execution module; the tool information management module performs basic information maintenance, statistical information query, warehouse location management, distribution information management, tool inventory management and system management functions; the tool information management module outputs tool parameter management instructions to the process management module, and the process management module transmits process procedure tool information back to the tool information management module; the tool information management module and the distributed numerical control module transmit tool cutting parameters to each other; the resource planning module archives the tool supplier catalog to the The tool information management module outputs the tool procurement plan instructions to the resource planning module; the tool information management module outputs the tool borrowing flow record, tool management data statistics and tool inventory information to the manufacturing execution module respectively, and the manufacturing execution module transmits the personnel information, equipment information and plan information back to the tool information management module respectively; this tool management method adopts a database as the basis, and realizes data interaction between each module by transmitting information with the database; and comprehensively considers and analyzes inventory warnings with workshop production plans, tool service life, procurement cycles and other information to establish an accurate inventory warning model; thus, the information-based turnover model is used to improve the accuracy and convenience of tool circulation; and the inventory warning model is used to improve the efficiency of tool use.
