Most of the current control systems can be traced back to the development of this system, that is to say, it has a history of 30-40 years. One of the bottlenecks at that time was the download speed of RS-232 connection. This kind of control system can read 5000 program segments per second. For many parts of the processing program, this speed is enough, but for complex parts, the required speed is much higher than this speed. When Mr. Carlo Micheli of MTI company began to develop his own control system, he adopted a new method for PC language logic and effective information processing. Its product is a numerical control system based on modern PC hardware, equipped with a new tool path algorithm, and its reading speed can reach more than 5000 program segments / s. GBIC cinnati said its results have met the "constant speed" processing requirements, its production speed is fast, and the feed rate is very stable.

The machine tool combines the rapidity of modern control technology with the precision of machine tool movement to form a real constant speed processing system. The control system of the machine tool may become an obstacle to shorten the processing cycle and improve the finish of complex 3D models, aerospace parts or medical devices. When the processor can't keep up with the running speed of the program, the driver will reduce the feed speed of the tool due to the urgent need of information, thus prolonging the processing cycle and leading to the uncoordinated operation of the tool. In order to replace the worn and overloaded tools, in addition to increasing the number of tool runs to the tool library, it will also affect the effective utilization of the spindle, increase the workload of fitter and finishing time.

When the speed (feed rate) is unstable, there will be some problems. When the cutting tool runs through the part processing, its uneven movement will cause different loads on the cutting groove of the cutting tool, thus affecting the machining accuracy and surface finish. If the running speed of the tool is not fast enough to maintain the minimum cutting load of the tool, friction will occur between the tool and the workpiece instead of cutting, then the unstable movement of the tool will shorten the service life of the tool. This operation mode will also cause a small amount of fracture gap of the blade, which will make the tool hot and blunt. However, with constant speed processing, the average processing speed of the tool through the workpiece will be more uniform, and the processing accuracy will be higher, which can not only shorten the processing time, but also extend the service life of the tool.

In the "revolutionary" series of machining centers, MTI's control system does not produce excessive stress associated with high-speed machining, allowing fluid tools to run on the geometry of complex parts.

In the process of program execution, the result of high-speed program processing is that the random error of the control system can be stably monitored and adjusted, so that the tool can run at a constant speed and achieve a perfect surface integrity. The system uses more than 80 high-speed buffers to monitor the operation of the tool. If the random error is exceeded, the tool movement can be adjusted immediately.

Even when machining very complex shapes, it is said that the rapidity of the control system, the fine adjustment of the driving device and the processing of the tool path can achieve the purpose of fast and accurate program execution.
