The IJKL vertical grinding machine has a total of eight axes to be controlled: a grinding wheel moving feed shaft including a right grinding wheel frame, a grinding wheel trimming feed axis and a grinding wheel rotating spindle R for providing grinding power; a grinding wheel moving feed axis of the left grinding wheel frame, and A grinding wheel rotating spindle R for grinding power is provided, and the workpiece is rotated to realize a workpiece rotating axis R of the workpiece circumferential grinding. The R axis is jointly owned by the left and right grinding wheel frames. The movement of the left and right grinding wheel frames is controlled by different operating stations under the control of the same set of 4 systems. The different machining parts of the same workpiece can be ground at the same time. The system information is displayed by the installation on the operating station. The unit is independently displayed to realize the exchange of human-machine information. The numerical control system has high control precision and fast dynamic response, which can meet the requirements of high-precision control of vertical grinding machines. CNC vertical grinding machine axis control requires positioning accuracy, repeat positioning accuracy, and the control resolution of the CNC system is not low and reliable. CNC vertical grinding machines are large-scale high-precision equipment, which is a single process equipment in the production process arrangement, which plays an irreplaceable key role in normal production. Therefore, the required numerical control system must have stable operation performance and advanced technology. The maintenance spare parts are sufficient and the maintenance service is timely in the current and future years. The CNC system is open. Open enough internal interface to facilitate secondary development of the vertical grinding machine control requirements, to optimize the control system, suitable for stable control of the vertical grinding machine. Development of control systems. The choice of the numerical control system is to fully exert the performance of the grinding machine, and the service production requires the selection of a high-grade numerical control system to control it. The design uses Siemens' numerical control system for large machine tools to meet the requirements of controlling the axis. At the same time, it adopts 0165174, digital AC servo drive device and human-computer interaction device 8,9:998A:9BA and the 0123451 CNC system. 6C, 6DE9BAEC9, select Siemens, F series AC servo motor, CG8 is composed of built-in CG8 plus expansion 1H6 interface device integrated in system 2832E: 8ABEA3B. Siemens is a fully digital, highly open CNC system that was successfully introduced to the market in the late 1970s. Its CNC system and driver interface signals are digital. Its human-machine interface is LMANKI based on FJ6K. It is easier to operate and master, and the software content is more abundant. With a highly modular and standardized structure, it integrates the 828 and drive control on a single board, integrating all the hardware and software of the closed-loop control into one square centimeter of space for easy programming, operation and monitoring. It uses a bit microprocessor to implement 828 control, which makes motion control more accurate. The numerical control system can also limit the working area by setting the soft limit switch in advance. When overtraveling, the program can be triggered to decelerate to meet the safety control needs of the machine tool. CNC system 28 programming is a program editor with high-level language programming features, which can be programmed in metric, inch size or mixed size, which can bring great convenience to the machining programming of the grinding machine. The system is provided with standard C8 software, hard disk, Pentium processor, and users can develop a custom interface under LMANKIHHOC. Equipped with 50HPPQ universal operator interface, data input H output can be simultaneously input through the common interface during processing. With Siemens C812 software, serial data bidirectional communication can also be performed with Siemens programmers or ordinary personal computers. On the 8, the "0B9EBRDPAA" software can be used to optimize the speed loop and position loop of the axis. In addition to the bit information, there is information in bytes, words, and double words in addition to the bit information between the functional blocks, and thus the data block 4 is also referred to to realize the transfer of the data information. The reference to the data block achieves the effect of data sharing, improves the code efficiency of the program, and shortens the code length. (Finish)
