With the intensification of competition in the manufacturing industry, more and more enterprises need to respond to the multi-variety and small-volume supply requirements of users; in many research institutes, many products need to be quickly redesigned, quickly produced, and then improved until stereotypes; It brings new challenges to the production technology department, and needs to cope with the pressure of rapid delivery; it needs to deal with the production management problems of undesigned products while designing and improving. In order to adapt to these challenges, the process technology department adopts a professional CAPP system, which can greatly improve the management level of the process technology, timely transfer data to the production system, and timely transmit the change data to the production department, thus ensuring the smooth progress of each production batch. The following describes the specific role of the CAPP system in combination with the application of several enterprises.
Second, the process department situation introduction
The process department is not an isolated department, but an organization that closely matches design and production. The workflow of the general enterprise process department is as follows:
1. The process department receives the drawings submitted by the design department, and the process leader divides the work by the process leader;
2. The craftsman prepares the card, prints the paper into a medium card, and submits the approval;
3. The approving personnel approves the card, signs the opinion, date, and signature;
4. After the examination and approval is completed, the fixed-time group of working hours shall be submitted for fixed-rate accounting;
5. The quota staff finds the data, estimates and calculates the working hours according to the experience, and fills in the card;
6. After the completion of the working hours, the technicians prepare various summary reports;
7. After the design of the process documents is completed, the production department will be sent to the production department to end the process design process;
8. In the production process, process change requirements are generated and the process change control process is entered;
Process personnel not only have to undertake a large number of process documentation tasks, but also need to prepare a large number of production documents according to different production batches. If the process documentation is mainly manual, for example, using Word format process files, the process file design information cannot be effectively integrated with the process. The process personnel need to compile a large number of similar cards and reports, the efficiency is very low, and the process file management is inconvenient. Restrict the bottleneck of the product development cycle.
In this case, the process department should adopt a professional CAPP system to achieve integration of design resources and automation of process documentation. The flexible preparation of the process documents and the automatic generation of the process reports are realized, and the efficiency of the process documentation is greatly improved.
The author explains how CAPP can improve the efficiency of the process department in the implementation process of a typical enterprise.
Third, an enterprise implementation content
An enterprise is a typical research and production-oriented enterprise. A large number of product design tasks are arduous. New products require strict process flow to ensure the current production deficiencies and quality analysis to ensure continuous improvement of products.
Enterprises urgently need to solve the problem of rapid preparation of process documents, automatic generation of batch reports, and updating of process documents during product transfer, so as to provide accurate data to the production department, so that production can proceed smoothly as planned. According to the current level of domestic CAPP development, the company chose XTCAPP, a well-known enterprise, as an application platform, combined with partial customization to achieve the specific needs of the enterprise.
Fourth, the implementation results
The main tasks of the implementation are as follows:
1. Completed the customization of all the technical documents marked.
There are many formats for the company's process documents, and there are a variety of production reports for the process department. These process files basically have continuation pages, and the workload of template customization and modification is very large. The two sides adopted a method of division of labor and cooperation, and completed the complete customization of the process documents in a short period of time.
2, to achieve full integration with the design documents
Extract the information of the design file, automatically generate the product structure tree in CAPP and realize the browsing of the design file. In the preparation of the process file, the product information can be flexibly extracted, and the three-dimensional map, the two-dimensional map, the word file, and the like can be browsed.
3. Strengthened the authority management of CAPP system
The system provides secure and reliable rights management, including product permissions, card permissions, personnel permissions, group permissions, and even permission control for different areas of a card.
4. Provide flexible and convenient basic data management
The process resource structure tree can be established according to the enterprise habits, and the original word and excel format process data can be conveniently imported into the process database, and the filter conditions can be flexibly defined, and only the necessary basic data is displayed when the basic data is called.
5, automatic generation of various process reports
There are many reports in the enterprise's process files. The CAPP system provides a powerful reporting tool that can automatically generate various reports directly according to the company's filling habits.
When generating reports, you can flexibly configure the BOM, generate various reports according to the configured BOM, automatically generate various schedules and summary tables, process file directories, and automatically generate batch reports: different production batches, need to re-do the complete set of process reports , statistics for each batch of material. With the report function of CAPP, it can not only realize automatic calculation of batch report, but also generate multiple batch reports at one time, which greatly improves the efficiency of programming of process reports.
6, the automatic stage of the process file
According to the production situation of the product, the design drawings and the design BOM are changed. The information corresponding to the design BOM in the process card is also automatically updated, and the BOM of the part in the transition phase is automatically changed. Refresh.
7, pass data for the ERP interface
The BOM can be formed according to the process file and the design BOM, and the information such as process equipment and process materials can be extracted and counted, and the process route can be directly generated, and the interface data can be transmitted to the ERP system.
V. Summary
CAPP system not only helps enterprise technicians to quickly compile a large number of process documents, but also provides good support for enterprise production management, quickly outputs a large number of reports, and can generate batch reports to meet the needs of enterprise production.
