At present, the developed two-axis lathe control system can be automatically generated by using the developed software chip and integrated tools. We are developing graphical application system analysis and integration tools.

3 Promptly carry out research on the research of open control system in China
CNC technology is the foundation of manufacturing technology and is the key to improving product quality and performance, reducing product costs and shortening production cycles.
3.1 Status and Problems At present, there are four open control systems in China: Huazhong I, Zhonghua I, Aerospace I and Blue Sky I. Domestic open control systems have their own advantages, but from the perspective of the development of numerical control systems, they do not have the essential characteristics of open control systems, and there are still many areas for improvement.
First of all, the concept of an open control system is not clear, and there is no platform problem to solve the open control system. The architectures adopted by each system are inconsistent, still self-contained, lack of compatibility and interchangeability between each other, and the description of the architecture is limited to the specific implementation layer, and is not improved to the theoretical and abstract levels. Therefore, the hardware and software of each system are not portable and interoperable.
Second, new operating systems such as Windows, UNIX, and OS/2 have not been fully utilized. Software development ideas and technology are backward, always at or below the level of structured programming. New theories and new technologies in software engineering such as object-oriented and software reuse are not fully utilized, and these are the keys to implementing an open control system. In addition, product upgrades, updates, modifications, and repairs still rely on the manufacturer, without the corresponding development tools and environment, and users cannot incorporate their own or any third-party ideas or products into the system.
Generally speaking, the situation facing China's manufacturing industry is as follows:
(1) China's manufacturing industry has huge demand and power for open manufacturing control systems. China's manufacturing and manufacturing organizations are faced with the arduous task of adjustment, transformation and optimization. Therefore, there are research and development including open control systems. The huge driving force of the new generation of manufacturing technology; the backwardness of products, the low level of technology, the low content of information, and the slow replacement and replacement have become the bottleneck restricting the development of China's manufacturing industry. Therefore, there is a need to develop an open manufacturing control system; The production units adopt different standards and form different closed systems: different communication protocols and data structures, so that information exchange between different devices is impossible, and information cannot be transmitted between different software. Different databases There is no way to share data, so there is an urgent need to implement an open manufacturing control system.
(2) China's production and market will be further integrated into the vast international market to face fierce market competition. To make our products have a place in the international market, we must improve the technical content and performance indicators of products as soon as possible, and internationally. Connected. The numerical control system, whether it is used as a commodity itself or as a processing means of goods, requires it to be an open control system.
3.2 Suggestions for the development of China's open control system The fundamental purpose of each foreign research program is to expand the share of its products in the international market, or at least to consolidate existing market positions. For example, OSACA in Europe targets the competitor Japan directly, with the aim of making European manufacturing system suppliers overwhelm competitors in the market. As far as the current level of China's CNC system products is concerned, if we do not take decisive and effective measures, we will not have a foothold in the international market, or in the domestic market.
The study of the open control system that OSCE called the third revolution of manufacturing has brought new opportunities for the development of China's CNC industry. We should seize this great opportunity to quickly carry out and deepen the study of China's open control system, and formulate the short-term and medium-term goals and plans based on the actual situation in China. Based on the development of open control system standards, we will launch them as soon as possible. China's new generation of open control system products.
No technology is isolated, and technology is constrained by economic, cultural, technological foundations, social structures, management systems, and personnel quality. To carry out research on open control systems, we must learn from but not copy the experience of foreign countries. We must down-to-earth, recognize the situation, and seek economic and effective development paths based on China's national conditions and the situation of enterprises. We believe that according to China's manufacturing automation "10th Five-Year Plan" and medium- and long-term development planning, the research and development of open control systems based on digital manufacturing is urgent for the manufacturing industry, and must not be taken lightly, must be recognized from the depths of thought, immediately The necessity and urgency of carrying out research on open control systems in China. To make the following recommendations:
