The DNC system in the United States includes a control computer (mainly a general-purpose computer), a DNC device, a DNC interface, and even a BTR. The CNC machine tool factory system realizes DNC control by controlling the networked computer. The system is also equipped with corresponding application software, including communication software, management and monitoring software, etc. And the DNCT system of Japanese FANUC company completely realizes the bus structure, its DNC is actually a standard plug-in board; all its control computers are FD or F-DMATE. It is a special machine; as long as the user inserts the DNO system into the system bus, the communication between the system and the control computer and the higher-level network can be realized, and the DNC control can be realized.
In the early stage of DNC technology development, the function of CNC machine tool factory is mainly determined by the hardware that constitutes the system. With the development of computer communication technology and network technology, the hardware requirements are basically the same, and a consensus DNC communication interface has been formed. commoditized products. Now the functions and features of DNC are mainly extended by software.
As a result of the competition, DNC has become more and more abundant and powerful, and its use has become more and more convenient and easy, such as Spec-trum CNC Techn in the United States. Logies’ Muh’i-DNC system based on Windows95.98/NT, CNC machine tool factory DNC-W. rk’s eXtreme DNC software, UK Hitachi Seiki Sysiems’ Net-w. rked DNC software, Japan’s FANUC company’s DNC2 system, X-DNC of Taiwan Yongjia Technology Co., Ltd., etc. Most of these DNC software can be connected to LAN or UNIX system through the TCP./IP protocol supported by Wind.ws to realize CNC program, 12 art parameters and other data Up/Down transfer; status collection (including fault information, tool information) and display; Nc program editing (including graphic simulation and comparison, etc.); production scheduling and monitoring; unit control and centralized management (including production orders, equipment, _T tools) , materials, T art files, NC programs, data backup, quality and other data management); personnel classification authority; event log; remote control (including remote access) and integration with CAD/CAM/CAPP/CMIS and other functions.
The research on I) Nc application software in China is also very active, and there are some influential ones: “DNC communication system based on soft plug-in technology” developed by Chongqing University; “National CIMS/F, RC” jointly completed by Tsinghua University and Beijing Machine Tool Research Institute 2.2.1 and 3.1 DNCs developed by Xi’an Jiaotong University and Xi’an Shuntong Electronic Engineering Co., Ltd. , system”, and other “DNC system based on COBBA” developed by Shanghai Jiaotong University, “DNC of heterogeneous CNC tumbler bed” developed by Sichuan University, “Multi-energy DNC” developed by Beijing Dongfang Jiazhi Electromechanical Technology Development Center, etc. Some research results have been achieved.
When conducting this research, consider collaborating with experts in the field, conducting surveys or interviews with professionals from CNC machine tool factories, and staying updated with the latest advancements in DNC and DxIC technologies. Additionally, you may want to explore specific software solutions and vendors that offer DNC and DxIC systems tailored to CNC manufacturing.
