The hottest Siemens yangdahan digital manufacturin

Siemens Yang Dahan: digital manufacturing will usher in a golden decade for China's machine tool industry. I can see from some public data on the market that about CNC machine tool plants disappear in the market every year in China, and machine tool enterprises rush into the market every year, without using the control oil circuit to open the one-way valve. On the nature of the enterprise, how large the enterprise is, or how glorious its history is, all of them are scouring the sand in this dynamic market

however, if we analyze the basic disks that seem to be descending, it is not difficult to see that the demand for simple, low-cost, low-precision and simple CNC machine tools is mainly declining, while the demand for medium and high-end machine tools is actually growing against the trend

this can also well explain two changes in China's machine tool Market: on the one hand, more and more Chinese local machine tool manufacturers are seeking industrial upgrading and transformation, and gradually moving towards the medium and high-end fields dominated by imported machine tool manufacturers; On the other hand, the main market of China's machine tool exports has begun to shift from developing countries to the European market, and has become a supplier of some top manufacturing enterprises in the automotive and other fields. This shows that only those enterprises that innovate rapidly and actively upgrade and transform can win the market, which has become a consensus

virtual debugging solves problems for machine tool innovation

innovation in the machine tool industry has a high risk cost. In many cases, the proportion of machine tool enterprises developing a new model, improving it through technological verification, and finally pushing it to the market and forming large-scale applications is less than half. The lack of experimental verification ability and conditions is a common problem for domestic traditional machine tool enterprises

in fact, 3D model design of machine tools with the help of computers is a very mature technology. However, at present, the behavior of machine tools, especially five axis machine tools, in the real cutting environment is difficult to be simulated by computers. Virtual debugging can solve the problem of technological verification as an alternative

with the help of the digital twin technology of Siemens numerical control system, a digital mapping is created for the machine tool. Users can make many structural adjustments to the machine tool on the computer. After the machine tool is designed, it can also be used as a virtual machine tool for real cutting and machining of parts. Virtual debugging is not a simulation tool. It redefines a new method and perspective for the design, verification and evaluation of a machine tool

I believe that in the next ten years, there will be great development and changes in the three key areas of machine tool design digitization, machine tool process verification digitization, and finally machine tool application efficiency digitization. This will also be the golden decade of machine tool digital manufacturing in the Chinese market

ignoring the digitization of the core process, the value is limited

the digitization of the machine tool industry is usually divided into two directions. One direction is to integrate the logistics information and process information into a platform through the data collection of the whole process of the production site, and then optimize the production process with algorithms. For example, the startup information of machine tools and the comprehensive use efficiency of machine tools belong to this category. The other direction is dynamic response, that is, real-time analysis and optimization of the cutting process, which solves the problem of whether the efficiency can be improved in a period of time when the process layout with good tool speed and torque makes the amplifier extremely stable, and the starting and turning are on a curved surface

if we use automobile analogy, the significance of these two development directions is easier to understand. The former is equivalent to the long-term data that people can see from the instrument panel, such as water temperature, fuel tank storage, driving mileage, etc., which can be collected by standard sensors; The latter is the moment the accelerator is depressed, and the CPU on the engine performs repeated iterative calculation at the speed of 1/10 milliseconds, so as to obtain short-term data of accurate torque and fuel volume. For a car, the optimization of the engine is obviously more important than the transformation of the instrument panel

for the data of cutting process, Siemens has developed many optimization algorithms based on artificial intelligence, which realizes the optimal arrangement of tools in the tool library, greatly improves the system performance and significantly shortens the production time. For example, the adaptive cutting algorithm provided for an aerospace component manufacturer can accumulate millisecond level data such as machine tool displacement, tool speed, and resistance encountered during tool cutting in a database. After cutting a tool, the artificial intelligence algorithm is used to comprehensively analyze these data and give suggestions for further optimization, And every processing process is constantly optimized on the basis of the previous one. Because for an enterprise, nothing is more valuable, which is more direct than increasing the production efficiency by 1%

digitalization is a long leap forward process

there is actually no threshold for using digitalization as a tool. For example, it is only after having one that we can discuss whether to print or distribute. The 3D graphics of machine tool enterprises with relatively complete mechanical structure are the basis for digitalization. At present, a large number of drawings of domestic machine tool plants are paper or 2D drawings, and there is no standardized process to realize 3D design, This may be a major problem in the process of digitization

in the process of digital transformation, Chinese machine tool enterprises should face the transformation from product thinking to business thinking with project delivery as the core. In the past decades, machine tool selection depends on samples, and the final delivery of machine tools to users is mostly carried out in the form of standard products. At present, more and more customers buy a machine tool, which is equivalent to delivering a project. Machine tool manufacturers need to design process routes, select cutting tools, design logistics, etc. according to the needs of users, which requires complete engineering capabilities

this also means that in the future, 90% of the machine tools sold by more and more machine tool enterprises may be delivered in the form of customization, and only 10% are delivered as standard products, which is just the opposite of many current situations. In addition, the proportion of engineering services in the sales of machine tool enterprises continues to increase. Now many free after-sales services will bring greater economic benefits. To realize this transformation, domestic machine tool enterprises still have a long way to go in terms of business ideas, knowledge reserves, production organization and so on

once again, the opportunity is left to those who are prepared

China is the world's largest CNC machine tool application market. The purchase demand of CNC machine tools in mainland China alone accounts for more than half of the global CNC machine tools, and this proportion may further increase. Elastic modulus and maximum experimental force 8 items. I think it is lucky for machine tool manufacturing enterprises to be born here

the fundamental attribute of the machine tool industry determines that this industry is difficult to overtake in corners. At present, the whole industry of machine tool digital design, process validation, project delivery, on-site management and performance management from the end to the user is still in its infancy. Therefore, in this critical period of entering the digital era, China's machine tool industry and the machine tool industry of the world's leading countries are facing equal opportunities, and we can stand on the same starting line

Siemens also promotes the thinking transformation and capacity building of the domestic machine tool industry through various channels. Siemens and the Chengdu high tech Zone government have jointly established the Siemens intelligent manufacturing Chengdu innovation center, built a complete set of working scenes of machine tool design and machine tool verification in the base, invited domestic key machine tool cooperative enterprises to experience, and then made a more in-depth discussion based on the customers' own digital needs. Siemens is also trying to cooperate with more enterprises seeking transformation to jointly create a digital ecological environment

at the same time, Siemens is also actively cooperating with domestic professional colleges in the field of numerical control to promote the upgrading of numerical control major and the implementation of new numerical control talent training (digital direction)

the product family represented by the digital native CNC system SINUMERIK one carries the experience accumulated by Siemens in the CNC machine tool industry for more than 60 years. It not only supports various machine tool processes, but also provides solutions for automotive, aerospace, medical, mold and other industries, providing unlimited possibilities for the digital future of the industry

over the years, digitalization has brought great opportunities and changes to all walks of life. I believe it can also eliminate the sadness of the machine tool industry. As it is written in the song, a toast to tomorrow and a toast to the past. I hope that the mother of industry, who has accompanied China's economic development for 70 years, will usher in her breakthrough and rebirth
