Part III   第三部份



Ericssonand the Fraunhofer Institute for Production Technology (Fraunhofer IPT) worktogether to develop new methods to improve industrial control processes anddetect defects in the manufacturing process in real time. One of the areas ofapplication is the production of leaf discs, which are an important part ofturbines in jet aeroengines. They consist of a wheel and a number of bladesaround the edge of the wheel. Leaf disc manufacturing is a typical applicationfor metalworking.

Ensuringthe high quality of the leaf disc is essential, and the high quality leaf discis the guarantee of the safety of the aero engine. The leaf disc is processedby milling machine, and many problems are encountered in the processing. Themost critical problem is that the processing process is difficult to monitor,which is a common problem in the metal processing field.

Thismeans that the operator can't know the result before the milling process isfinished, and a milling process can last for 1 day or even 100 hours. Due tothe processing defects, the rework rate of the final processed product is oftenas high as 25%. Prolonged the overall production cycle.

Thereare many reasons for machining defects, but the main reason is the vibration ofthe milling cutter or the machine itself, which affects the machining results.This vibration can be found by monitoring the machining process in real time,and the machining process can be optimized in real time through data feedback.Ultimately reduce the rework rate. Failure to find problems in the processingprocess in a timely manner is a phenomenon that exists in the entiremanufacturing industry.

Althoughthe leaf disc processing is only a specific case, the vibration problem in theprocessing process is widespread in the machine tool processing field. The leafdiscs that will be manufactured in the future will move in a thinner direction,and the processing results will be more susceptible to vibration.

FraunhoferIPT's solution to this problem is divided into two parts, real-time monitoringand real-time control -

real-timemonitoring

Thesensor is attached to the blade part, and the communication module is added tothe wheel part, so that the result of the leaf disk processing can be monitoredin real time, and if there is a processing defect, the further processing ofthe defective component is stopped in time, or the defect is started to startrework;

Real-timecontrol

A datamodel is established for the machining process, and the machining process inoperation is adjusted in real time according to the data of the machiningresult, such as changing the rotation speed of the milling cutter to avoid theoccurrence of machining defects.

Theultimate vision is to build a fully automated factory that connects all thedevices and integrates and manages them through a unified system.

However,current communication technologies are not well supported by this solution, and5G is the key to this solution. In this case, the biggest advantage of 5G isthat it can provide extremely low latency and stable network. In order toachieve real-time control, the sensor information needs to be responded to andprocessed within 1 millisecond. 5G ensures the real-time control by providingextremely low latency, thus ensuring that it can be applied in the process ofleaf disk production.

Fraunhoferalso measured the economic value of introducing 5G improved productiontechnology. The traditional leaf disc processing rework rate is as high as 25%,which means that one out of every four leaf discs needs to be reworked. Thiscost is very high, and reducing the rework rate can produce great economicvalue.

Ifautomation is achieved by introducing 5G and IoT technology, the rework ratecan be reduced by 10%, which is equivalent to reducing the processing time perunit of product. In terms of machine cost, the cost of a single-leaf disc canbe reduced by 3,600 euros, and the global production of leaf discs is about100,000 a year. This means that real-time monitoring through 5G technology cansave 360 million euros a year.

Miningis the basic industry for global economic activities. The market is huge. Thetotal annual income of the top 40 mining companies in the world exceeds 500billion US dollars.

Improvingthe profitability of the mining industry requires unremitting efforts in miningefficiency, transportation and metal extraction technologies to optimize theflow efficiency of the ore. However, the increased investment in these areas isfacing the problem of diminishing marginal effects. Automation is becoming anew opportunity and focus for the mining industry. A prerequisite forautomation is that the mine has a relatively complete network coverage andconnectivity, and the environment in the mining area is harsh. Deploying amobile communication network is a better solution.

Sweden'sBoliden is one of the world's top mining companies with eight mines around theworld, and the Aitik mine in northern Sweden is Europe's largest open pit mine.Boliden and Ericsson jointly formed a research team to explore how 5Gtechnology can help the mining industry improve efficiency and economic value.

Aitikis a rapidly expanding mine that must transfer large amounts of rock in orderto obtain copper ore. The amount of stones transported back and forth in themine every year is increasing. Depending on the location of the ore, the rocktoe ratio is different. On average, one ton of rock is moved for every ton ofcopper ore. Aitik's current annual production is 36 million tons of ore, and isexpected to grow to 45 million tons soon, so the amount of rock that needs tomove will increase accordingly.

Thecomplexity and volatility of the mines is very high, adding giant equipment toremove rocks and keeping the utilization of these new equipment is not a simplematter.
