Theoretical basis of automation of machine design and manufacturing
With the continuous development of productivity level, the automation level of mechanical design and manufacturing has reached a relatively high degree.
However, at present, people are no longer satisfied with the simple and repetitive labor of mechanical parts. With the advent of the information age and the rapid development of information technology, the technical level of automation has gone far beyond the above-mentioned simple and repetitive labor. The development trend towards intelligence can be changed by the computing control system according to the changes in the environment, and even self-diagnosis and maintenance can be carried out in case of failure. Automation in the field of mechanical design and manufacturing, first gobbled up in the middle of the last century, was born with the development of computer science.
Half a century, through the engineers and technicians continue to research and development, mechanical design and manufacturing automation has developed to today’s stage of intelligence. From simple to complex, from local to overall, gradually occupy a more important position in the production of machinery.
The current situation of the application of mechanical design and manufacturing and its automation
China’s mechanical design and manufacturing and its automation, can be said to be around the development of the new Chinese industry at the same time the start. Through the efforts of several periods, it has been able to reach the international advanced level.
However, compared with other developed countries which started early and developed fast, there is still a big gap. But since the beginning of the new century, especially in the last decade, China’s machinery manufacturing and its automation has made incomparable achievements. This is inseparable from the solid industrial foundation laid by China since the founding of the country.
China now has a number of industrial design and manufacturing enterprises in the world can achieve a leading position, with its low cost, high efficiency and a wide range of production in the world has equaled or even surpassed many developed countries of the old enterprises. However, there are still problems such as unreasonable industrial structure and overcapacity; at the same time, some smaller manufacturers, there are still various “native methods”, “stupid methods”, the automation level of mechanical design and manufacturing is low.
Some enterprises have “anti-intellectualism” tendency. For example: a manufacturer in order to check out the packaging boxes over the assembly line, the use of fan blowing away the empty boxes and achieved the leadership of the praise, but this practice is contrary to the idea of the development of productive forces, want to really solve the problem, we must really pay attention to the application of science and technology, to enhance the level of automation of mechanical design. But we believe that, under the leadership of the Party Central Committee, China’s mechanical design and manufacturing as well as industrial level will certainly cross a new level.
Research on the application of mechanical design and manufacturing and its automation
In the field of mechanical design and manufacturing and its automation, China still needs to learn the automation experience of western developed countries, and really achieve international standards. With a unified standard and unified product quality will China’s mechanical design and manufacturing and its automation level to the global level. Its main principles should contain the following points.
Meet the functional requirements of the machine
Any machine must have the three major elements of industry, namely, the input and output of matter, energy and information. Therefore, for the automation of machine design and manufacturing must also meet the above three elements. Through the main function of the designed system, the above three elements are transformed, transferred and stored. However, no matter how high the degree of automation of machinery, it must not get rid of the human control.
Continuous innovation using advanced technology
According to the function of the mechanical system, it can be briefly divided into the following categories: First of all, it is a processing machine, which is for the purpose of material handling and processing. Through the input of material, energy and information, the processing of a class of machinery, such as machine tools, furnaces, a variety of cranes or transportation. It is a more common type of machinery; second is the power machine, that is, the output energy system, such as thermal generators, internal combustion engines, etc.. The third is the information machine, with the processing of information as the main output. For example, computers, various instruments and sensors, etc. In the current development trend of machinery design and manufacturing automation, the boundaries of the above three types of machinery are gradually blurred. For example, through the information machine to sniff the working environment, the formation of electrical signals for information processing, and then control other components for work production. There is a large space for innovation.
The development trend of mechanical design and manufacturing and its automation
Mechanical design and manufacturing and its automation have brought great convenience to people’s production life, thus forming a positive feedback mechanism. In the future, the level of automation in mechanical design and manufacturing will be even higher. Its main trends are as follows.
First is more diversified. As explained above, mechanical design and manufacturing and its automation have gradually blurred the gap between mechanical fields, so its development will also be integrated with a number of technologies, thus more diversified. At the same time, the positive feedback mechanism mentioned above will also promote the development of this trend of diversity.
The second is more integrated. At present, the design, production, manufacturing and management of mechanical processing are run separately. However, with the development of machinery design and manufacturing automation, the factory will gradually reduce the manpower required, so the above division of labor will also be gradually blurred. The current rapidly developing artificial intelligence technology can not only realize the automation of production, but also the automation of design and management, which greatly improves the production efficiency of the factory.
The third is more energy-saving. As workers can manually operate the error is bound to be greater than the error of automated control of production, at the same time, automated computing and control will try to optimize production, reduce the waste of raw materials and energy, but also to make the production of various wastes generated by recycling or centralized treatment. The goal of energy and material intensification and energy saving is achieved. Greatly enhance the space of energy saving and emission reduction.
At present, it seems that the automation of modern machinery industry has the significance of multi-functionality, high quality, high reliability and low energy consumption in design and manufacturing. Therefore, the automation of mechanical design and manufacturing is cited as the general trend.
And at present, the development bottlenecks faced by the automation of mechanical design and manufacturing are mainly sensing and detection technology, information transfer and processing, interface technology, precision machinery technology and system theory. Therefore, to truly achieve the automation of mechanical design and manufacturing, there is still a long way to go.
Therefore, the majority of front-line mechanical designers should clearly understand the status quo, should take the initiative to the direction of mechanical automation design and manufacturing, which is in line with the general direction of science and technology development trend of the way out. As a qualified designer, should also clearly understand that in the process of mechanical design and manufacturing and its automation, can not rely on foreign technology, should be combined with the development of China’s mechanical design and manufacturing status quo, take independent research and development, independent design, independent creation of the route, which is the mark of China’s mechanical design and manufacturing to truly reach the world-class level.
