Realize the centralized management of workshop code and processing data;

Realize the process management of preparation, proofreading, signing and calling of machining programs, and realize the version management of machining programs in the enterprise network;

Realize visualization and transparency, make full use of the remote data feedback ability and data centralized management ability of the information system, facilitate the monitoring of various event management processes, and improve the controllability of production process management;

Monitor the production process and product quality in real time, obtain the equipment utilization rate, reduce the failure and downtime, reduce the use cost, save the time of statistical production data, and improve the efficiency of dealing with problems.

Project results

Equipment data acquisition:

1) Realize the workshop to obtain the on-site equipment operation status in real time in an automatic way, then regularly analyze the messy data collected such as equipment processing status and equipment operation parameters, and conduct orderly management to form standardized industrial big data and provide data support for daily maintenance of equipment.

2) Visualization and transparency are realized through on-site Kanban, production report and other means, and the integration ability and data centralized management ability of information system are fully utilized to facilitate the monitoring of various event management processes, real-time monitoring of production processes, obtain equipment utilization, reduce failure and downtime, reduce use cost and save the time of production data statistics, Improve the efficiency of dealing with problems.

3) Monitor the equipment production process. By reading the maximum speed setting value in the equipment NC code, the system analyzes whether the equipment status exceeds the rotation, and alarms when it exceeds the transmission.

4) Carry out research on MES automatic work reporting system and formulate automatic work reporting system.

5) The feeding parameters of the equipment are monitored in real time, and the keyboard input parameters of the equipment are recorded in real time.

Equipment communication:

1) The operator only needs to input the calling instruction on the control panel of the NC equipment to complete the sending, receiving and list query of the program (automatic transmission and online transmission of NC program).

2) It can realize the parallel online processing of multiple machine tools, support the continuous transmission of breakpoints, and realize the continuous transmission of automatic, manual and power-off breakpoints. It has automatic package filling, automatic defect filling and automatic character verification mechanism to ensure the accuracy of the program transmitted to the machine tool.

3) Different equipment types and different control systems can be connected to a unified network for management in different access modes at the same time.

4) Realize the remote list browsing of machining program. The operator can browse the corresponding file list on the server at the machine tool end, and select the program in the list to call.

5) Implement network card equipment or serial port equipment to ensure that only one NC program runs on the equipment according to the machining task.

The system supports cross network segment transmission.

6) Only the unique NC program of the current operation is reserved on all NC equipment ends.

7) The cutter compensation information file of the tool setting instrument is automatically uploaded to the DNC server for saving.

Procedure management:

1) Centralized management of workshop code and processing data, and process management of preparation, proofreading, signing and calling of processing program.

Push the NC program to the equipment according to the mo.

2) Database management of various information of NC program, such as program number, drawing number, part number, machine tool, user information, etc.

When uploading the program, the server can automatically receive and save the NC program, and there is no need for special personnel on the server side.

3) System communication log. The log function can view the transmission date, time, file name, upload or download and other contents to record the operator's operation process and error information.

4) Comprehensive log management is provided, and each operation of the user is recorded in detail, so that there are traces to follow and check, which can recover the misoperation in the system and provide important security guarantee.

5) It provides full life cycle (new, warehousing, outbound, publishing, republishing and archiving) management for documents, records each version, avoids the problem of version confusion due to too many document versions, and provides the function of comparing different historical versions.

6) User permission management includes personnel management, role management and related user management. Permission settings can be controlled to the component level. Fine user permission management, fine to the component level, different users, different permissions.

7) Product structure tree and equipment structure tree are provided in the equipment data management system to classify and manage workshop equipment and related products, parts and NC documents. Provide online viewing, online editing and online version comparison for NC documents, products and parts related documents.

8) The system supports pushing NC programs to equipment according to mo.

9) The communication parameters can be backed up automatically, and the machine parameters can be restored intelligently when the machine is moved or the system is reinstalled.

10) Provide the display of enterprise department tree and workshop layout.

System integration:

1) The equipment data acquisition system (MDC) is composed of multiple modules such as data acquisition and monitoring, statistical analysis, on-site Kanban and system integration. The on-site equipment data collection of the whole workshop is realized through the acquisition and monitoring system, and the collected data is normalized into report data that can be understood by the manager through the data processing platform, At the same time, the equipment operation flow information and equipment real-time status are fed back to the MES system, and the analysis report and general control Kanban are formed in combination with the equipment information collected on site.

2) DNC v7.0 system can be compatible with the existing DNC system and cannot affect the normal operation of the existing DNC system.

3) DNC v7.0 system can be compatible with the integrated interfaces of the original DNC system, PDM system and MES system to ensure the stable operation of the system.
