For CNC parts processing technology, it has corresponding systems and management. The control system can logically process programs with control codes or other symbolic instructions, and decode them by the computer, so that the machine tool executes the prescribed actions, and the blanks are processed into semi-finished parts through tool cutting. The CNC system is a dedicated real-time multi-task computer system, which incorporates many advanced technologies in today's computer software technology in its control software, the most prominent of which is multi-task parallel processing and multiple real-time interrupts.
Parallel processing means that the computer completes two or more tasks of the same or different nature at the same time or within the same time interval. The most significant advantage of parallel processing is that it increases the computing speed. Comparing n-bit serial operation and n-bit parallel operation, in the case of the same component processing speed, the latter's operation speed is almost n times faster than the former. This is a parallel processing method of resource duplication, which greatly increases the computing speed based on the principle of "winning by quantity". But parallel processing is more than simple repetition of equipment, it has more meanings. Such as time overlap and resource sharing. The so-called time overlap is based on the pipeline processing technology, so that multiple processes are staggered in time, and several parts of the same set of equipment are used in turn. Resource sharing is based on the principle of "time sharing", which enables multiple users to use the same set of equipment in chronological order.
In the hardware design of CNC systems, parallel processing methods with repeated resources have been widely used, such as the use of a multi-CPU system architecture to increase the speed of the system. In the software design of the CNC system, the pipeline processing technology of time-sharing and resource overlap is mainly used.
