What is DNC? Can an Industrial IoT Gateway do it?

DNC (Distributed Numerical Control) is a term commonly used in CNC machine tools. Its essence is a CNC system distributed in the workshop, which is composed of computers and machine tools with CNC devices using computer network technology.

The DNC machine tool equipment networking system realizes the interconnection and intelligent management of machine tool equipment in the production workshop, solving problems such as low efficiency of manual data entry and difficult management of processing programs. Based on equipment networking, the system collects and processes machine tool equipment data and production data to help enterprises and factories build digital workshops. It can form a monitoring system for modeling, programming, simulation and other processes, making CNC program management and CNC processing processes traceable, and providing basic data and scheduling basis for the MES system.

Because the data collection and transmission of DNC machine tools requires special deployment and development, and each model is connected to a special system, the applicability is relatively narrow, and the time and energy cost for enterprises is naturally high. However, with the development of industrial Internet of Things technology, the gateway can perform the functions of the DNC system, and it also has the advantages of simple installation and deployment, quick project results, stable and reliable operation, etc., which is favored by machine tool companies.

The data acquisition gateway developed by Wutong Bolin can collect data from major machine tool equipment, such as FANUC, Mitsubishi, Siemens, Mazak, and Huazhong CNC. It supports uploading machine tool data to the cloud through 5G/4G/WIFI/Ethernet and other methods, and centrally displays various data charts through the cloud platform. It can provide enterprises with machine tool equipment monitoring, workshop environment monitoring, process configuration monitoring, automatic alarm notification and other functions, create a digital machine tool workshop, and improve the level of intelligent automation management.

1. Data collection and monitoring

The industrial IoT gateway can be used to obtain machine tool operation data, and then understand the status of the machine tool in production, so that managers can promptly discover problems in machine tool operation, adjust the production status of the machine tool in time, and improve production efficiency. Through mobile phone APP and computer Web terminals, you can get the information you need at any time to build a digital factory.

2. Automatic fault alarm

By setting different alarm programs, you can receive automatic notification information via WeChat, SMS, email, etc., so you can send people to perform maintenance in time when the equipment fails. At the same time, in the event of an emergency, you can also obtain danger information through on-site sensors, quickly locate the site through surveillance cameras, take timely measures, and create a reasonable and scientific early warning mechanism.

3. Remote device management

The system supports electronic map display, showing the status information of equipment across the country (operating status, idle status, fault status, offline status, etc.). It can also remotely manage gateway devices, perform program upgrades, remote upload and download, etc., which can effectively meet the needs of equipment manufacturers, help improve service quality, and create a good corporate image.
