Numerical Control technology, referred to as numerical control (NC) technology, is a technology that uses digital information to automatically control an object. The control object can be displacement, angle, speed, temperature, pressure, flow, color, etc. The control system that adopts numerical control technology is called numerical control system.
The numerical control system that adopts general computer hardware structure and uses control software to realize numerical control function is called computer numerical control (CNC) system. A machine tool equipped with a CNC system is called a CNC machine tool. CNC machine tools are produced to solve the automation of complex profile parts processing.
Emergence of CNC Machine Tools in Shenyang Machine Tool Factory:
The introduction of CNC technology in the Shenyang Machine Tool Factory can be traced back to the late 1970s and early 1980s. During this period, China began to open up to international markets, and there was a growing need to modernize and upgrade its manufacturing capabilities.
In the initial stages, Shenyang Machine Tool Factory adopted foreign technology and collaborated with international companies to acquire the know-how for producing CNC machine tools. This technology transfer helped lay the foundation for the development of CNC machine tools in China.In 1948, the American PARSONS company first proposed the idea of CNC machine tools when developing a machine tool for processing helicopter blade profiles. After three years of improvement and research on white programming, CNC machine tools entered the practical stage, and commercial CNC machine tools appeared on the market. In 1958, KEANEY & TRECKER Company of the United States first successfully developed a machining center with a white moving tool changer in the world.
China began to develop CNC machine tools in 1958, and in the 1970s, simple CNC machine tools began to be used in production. They use the single-board computer as the control core, the digital tube as the display, and the stepper motor as the executive element. In the early 1980s, due to the introduction of 1:1 advanced CNC technology, the quality and performance of my I:9 CNC machine tools have been greatly improved.
They have complete manual operation panel and friendly man-machine interface, can be equipped with DC or AC servo drive, realize semi-closed or closed-loop control, can carry out linkage control of 2-4 axes, have tool magazine management function and rich logic control function. Since the 1990s, my country has begun to develop in the direction of high-end CNC machine tools. Some high-end CNC key projects have passed the national appraisal and have been applied in engineering.
At the beginning of the 21st century, high-performance CNC systems such as Aerospace I, Huazhong I, and Huazhong 2000 have achieved high-speed, high-precision, efficient and economical processing effects, and can complete five-coordinate real-time interpolation control to complete high-complexity surface processing.
