How Do You Think the Development of CNC?

CNC technology is a process in which a computer program is used to control a machine, and a mechanical part is processed according to a program developed by an engineer.Numerical control technology and numerical control equipment are important foundations for manufacturing industrial modernization. Whether this foundation is strong or not directly affects a country's economic development and overall national strength, and is related to the strategic position of a country. Therefore, all industrialized countries in the world have taken major measures to develop their own numerical control technology and its industry. This article mainly introduces the development of CNC.

 

 

CNC Hardware Technology

With the rapid development of integrated circuits and computer technology, the update of numerical control hardware technology has been developed. Modern numerical control systems generally use very large scale integrated circuits (VLSI), special purpose chips (ASIC) and digital signal processing (DSP) technology. Surface mount (SMT) and three dimensional high density technologies are widely used in electrical assembly to greatly improve system reliability. High-speed and high-performance storage technology is extremely user-friendly. As the core of the CNC system, the processor uses a high-speed RISC CPU above the bit to ensure high-speed and high-precision CNC machining.

 

 

CNC Open Development

There is no consistent definition of an open structure to date. Some users believe that the open representation can accept the communication protocol used locally; while others believe that openness means that all controllers operate exactly the same.For machine tool application engineers, openness means standard input/output interfaces for tool holder movement, sensors and logic control; for academic research engineers, openness means that all of these are from the building blocks that are used immediately. Piece. Due to pressure from end users and integrators, the development of open architecture is moving forward and will continue.

 

CNC technology attaches importance to the establishment of new technical standards and specifications. The numerical control standard is a trend of the development of information technology in the manufacturing industry. The open CNC system has better versatility, flexibility, adaptability and expandability. The United States, the European Community and Japan have implemented strategic development plans and opened up. The research and development of CNC system specifications (OMAC, OSACA, OSEC), which indicates the advent of a new era of revolution in CNC technology.

 

 

CNC Real-Time Operation

The numerical control software contains the idea of real-time operating system, such as task scheduling, memory management, interrupt processing, etc., but this technology is implicit, and each CNC system is unique and opaque. This situation is inconvenient for end users and system integrators. Today, with the increasing popularity of open CNC calls, it is logical to study the application of real-time operating systems in CNC software. In particular, the technology of embedded real-time operating systems is developing rapidly, which will have a revolutionary impact on the development of CNC control software.

 

Choosing a suitable commercial embedded real-time operating system to create a user-satisfied CNC system and a personalized CNC system will be the main direction of open CNC.
