The CNC machine tool adopting embedded industrial computer technology has a wide range of adaptability. It uses its computing power to meet customer requirements and has the network control capability, so that the embedded embedded IPC machine only needs to change the input program instructions when the processing object changes. Improve the processing performance higher than the general automatic machine tool, can accurately process complex profile, and thus suitable for processing small and medium batch, frequent modification, high precision requirements, shape more complex parts, and can obtain good economic results with numerical control technology The development of the use of numerical control systems, the growing number of machine tools, lathes, milling machines, boring machines, drilling machines, grinding machines, gear processing machine tools and EDM machine tools.

System principle
CNC machine tools are mainly composed of numerical control devices, servo mechanisms and machine tools. The program instructions input to the numerical control device are recorded on the information carrier and are read by the program into the device, or input manually by the keyboard of the numerical control device. The numerical control device includes a program read-in device and an input portion composed of electronic circuits, an arithmetic portion, a control portion, and an output portion. The numerical control device is divided into three types according to the control functions that can be achieved: point control, linear control and continuous trajectory control
CNC Machine Tool Network Technology Application
With the popularization and application of integrated CAD/CAM and local area network technologies, most companies have now clearly improved the efficiency and quality of new product design and development, process planning, and CNC machine tool programming. Production management has entered the era of networking. The management of CNC machine tools, which is closely related to CAD/CAM, is still in the original state and has become a bottleneck restricting the improvement of modern enterprise management. The realization of the networked management of the enterprise's CNC machine tools has enabled the company's management level to be newly improved.
First, the main issues before CNC machine tools networking
1. Program transfer
For some numerically controlled machine tools with relatively few program requirements, the manual keyboard input method has been used. The disadvantages of this method are:
(1) Low efficiency; (2) Length of time spent on the machine; (3) Error-prone.
For some CNC machines where the input of the program is large, a desktop computer is used on the machine side for program transmission. The disadvantages of this method are: (1) The environment is poor and the computer is difficult to maintain. (2) The use of commercial system software, adaptability and upgrading difficulties; (3) the operation method is complex, the operator's quality requirements are high; (4) multiple people operate a computer, the management of program files is confusing.
Some companies also use laptops for program transmission. Due to frequent plugging and unplugging of transmission cables, the laptop's serial interface can easily be burned.
Why is the embedded IPC a better choice? We can learn about the features of ARK-5280 provided by Advantech:
Second, develop solutions for problems
Through various investigations and studies, the internal LAN of the company has developed to a certain scale. It is already very common to create a CAD/CAM integration application for the purpose of improving the manufacturing of China to China. Therefore, CNC machine tools take the path of network management to solve problems. The best choice.
The composition of the system
The machine tool networking system includes: (1) network server, (2) LAN cable, (3) CAD/CAM computer, (4) management system, (5) networked system master controller, (6) remote communication interface, (7) Communication cable, (8) CNC machine tools.
Among them, the network server, LAN cable, CAD/CAM system and CNC machine tools are existing resources of the enterprise; the system management machine is an embedded industrial control computer with special networking software installed, and any client management software can be installed on the LAN. A computer as a management workstation; networked system management machine is a dedicated computer, running a customer management operating system, its role is to accept the scheduling of each workstation, to send commands to all CNC machine tools on the network, to achieve unified management of machine tool information; The communication interface device is a multi-serial distributor dedicated to the communication between the master control machine and the machine tool. Its feature is that it can realize long-distance transmission without signal loss.
After the implementation of the program:
After the CNC machine tools are networked, there will be significant improvements in NC program management and program transmission.
In a word, in China, after more than a decade of development, CNC machine tools have experienced difficult and tortuous development. Nowadays, in the era of the development of new and high technologies that will be created in China and further enhance China's manufacturing capacity and production capacity, the development of CNC machine tools will be even longer. progress.
Advantech adheres to the ePlatform concept of establishing a complete computing platform for customers in China's manufacturing industry. The ARK series of embedded industrial control systems that meet customer needs will make even greater contributions to China's manufacturing industry!
A Battery Charger supplies current to the base plate. Once the AGV is in charging position and the collector has made contact with the base plate, the AGV computer turns on the current.
The base plate has chamfered entry/exit ramps to facilitate smooth drive-on/drive-off of the spring loaded collector.
Battery charging stations may be installed anywhere within the system where the production process allows the AGV to stop (staging areas, turn arounds, loading stops etc.).
