Modern industrial manufacturing has higher and higher technological requirements for products. The combination of CNC machine tools and automation systems is getting closer and closer, and the dependence on software is increasing. Software becomes more and more complex, making it more difficult to control its reliability. As a result, failures, accidents and even downtime due to software and human factors account for an increasing proportion.
More worthy of attention is that the cost of software development in automation systems is increasing. According to reliable data, in the machine tool industry manufacturing system, in the 30 years from 1980 to 2010, the cost of software increased from 10% to 40%, the cost of electronic appliances increased from 10% to 25%, and the cost of machinery decreased from 80% 35%. In addition, the complexity of software increases exponentially as the software becomes larger, the development time required becomes longer and longer, and the probability of software errors continues to increase. It can be seen that the necessity of scientific management of the complexity of software is increasingly urgent.
Obviously, in the field of CNC machine tool industrial control, the engineering of software design must be fully implemented in its entire life cycle, that is, in the design phase, simulation phase, programming phase, debugging phase, on-site debugging phase, operation phase, and support service phase (for Supplier), maintenance phase (for users) fully implemented.
Among them, the programming language is the basis for the realization of software functions. For a control system, the importance of software is beyond doubt. What kind of programming language is used to compile application software, and to provide a solid foundation and sufficient support throughout the entire life cycle of the software, is critical. This programming language must be based on the theory of modern software engineering. To use it to realize the necessary functions of the software's full life cycle, it must first have the following characteristics: structured, decomposable, reusable, in software The execution process must be controllable, and at the same time must be able to be certified and confirmed.
In the future development of CNC machine tools, automation systems have very far-reaching significance. It can not only improve the traditional manufacturing level, but also meet the requirements of high-tech development, provide technical guarantee for machine tool manufacturing, promote new changes in the production method of CNC machine tools, and ease the constraints of the environment and energy on CNC machine tool manufacturing.
