4.0 Germany technology officer in the eyes of industry, the Internet of things, and big data

Franklin berger Group (Klingelnberg Group) dates back to 1863, now has to pass on to the seventh generation of the family.In 1993, franklin berger’s acquisition of Mr Likang (Oerlikon Geartec AG);In 1997, successfully conquer spiral bevel gear of dry cutting technology;Put into operation in 2008, the world’s most advanced large bevel gear production equipment;In 2012, the acquisition of hoff (h. fler Maschinenbau GmbH) core business.

today, franklin berg has become the world’s leading bevel gear, spur gear, the gear measurement, customized high precision gear parts research and development and manufacturing company.Franklin berg lead from the excellence of product and service quality, the reliability of the absolute and strict delivery time.

m & uuml;Dr Ller, industrial 4.0 is regarded as one of the largest in the current international industrial field is technology trends, however all walks of life for both the concept.So what do you think of this, industrial 4.0 have in common?
& have spent
hartmuth MüLler:
& have spent
our group think industrial 4.0 is a kind of inevitable trend, the whole industry to focus on this, but they contain different understanding for different industry.Therefore describe the trend of keywords are also different.For us, industrial 4.0 is the core idea of cyber physical systems (CPS).

what do you think, & other;4.0 throughout & industry;The concept is really appropriate?Really is a trend of the future?

industry is recognized as the fourth industrial revolution.I saw just now is something innovative, this innovation using some technical method gradually to the digital world and real world want to merge.

we talk about cyber physical systems, KLINGELNBERG based on the system’s first priority is to what?

hartmuth MüLler:

we are a specialized company engaged in machine tool production and precision measurement technology, the gear bearing the weight of the mechanical properties of the most important.Through our equipment, customers can create gear vehicles and industrial purposes.The gear can be a spur gear and bevel gear.It very high quality requirements, from the design process to gear products, cost is very high.
& have spent
by our method, the user can get to produce parts by digital twins, including the geometry of the digital image.On this basis, we can adjust our product digital model and the actual production process, so as to establish process quality control.And it is based on the concept of cyber physical production system (CPPS).

then the CPPS is how to change the whole process of the customer?
& have spent
hartmuth MüLler: we belong to the field is the machining parts.Traditional modeling based on CAD digital process begins with the design of the link.Production of CAD model is used to generate only specify the mechanical movement model in the case of tools, it will perform in the process of the preparation of the CAM and NC programming.Production base is used for data processing of the NC machine, a given tolerance, and of the drawings generated by CAD model.As to appear constantly in the process of production of error correction, the correction, need professional NC programmer or a new NC data to solve, to make up for the error.
& have spent
for gear, with the customer we understand is different: we will design process combined with continuous production simulation.So we are no longer only focused on the CAD model, but on the working conditions of a gear production.Based on the development of CPPS, digital twins included not only the geometric image, there are tools and components between geometry and motion description of production steps, namely so-called kinematics.So don’t need the process of CAD, CAM, because NC gear processing data were generated at the same time in the process of generating the process.

can better optimization process.But at present, there are also some technology, can be more surprises to optimize process, such as 3 d printing, how do you see?
& have spent
hartmuth MüLler:
& have spentAlmost
in the CPP system save a lot of the required data, the data must be in the future to be used for process optimization.
& have spent
for 3 d printing, it is indeed very applicable in many application scenarios.Especially in the rapid prototyping, or by machining is not possible, with complex internal structure of series product.
& have spent
but as long as you are able to machining products, and can reach a certain number of levels, 3 d printing is no longer a good choice.Economies of scale can’t use 3 d printing.

back to CPPS, we further discussed: what do you think the Internet of things play a role?
& have spent
hartmuth MüLler:
& have spent
the Internet of things (IOT) is to point to a higher level object interaction network connection, in the process has potential.For example, we can not only realize machine monitoring, real-time monitoring and planning of all other resources.
& have spent
in the field of machine tool maintenance, preventive maintenance is exact and effective method.In this case, based on statistical information, we will be able to detect the abrasion of the parts.In this way, we can go to replace worn components, but often these parts are not used to the life.
& have spent
along with the development of the Internet, people can be a big step from preventive maintenance to the predictive maintenance.By predictive maintenance, wear state of machine components by the sensors to detect and record in the digital system.Now that already know the wear state, we can timely replacement parts to life really fast.So, through the Internet of things people can use resources more effectively, so also more cost effective.

you mentioned, will generate a lot of data on the industry of 4.0.How do you think the development of big data?
& have spent
hartmuth MüLler:
& have spent
yes, it creates a large amount of data, but often people lost data speed is fast.Therefore, I am & other;The data analysis & throughout;Supporters of that support relatively controllable data set processing.First of all, the big data sounds is the feeling of a lot of data, but data alone asserts that is foolish.It will need a clever mind, data combined with prior knowledge, and benefit from it.
& have spent
we now have in the use of machine data to determine the abnormal situation of cause and effect.Correlation patterns lookup is beneficial to the determination of causation, namely the operator or environmental factors contributed to some anomalies.
& have spent
we can complete the data analysis, thanks to artificial intelligence, we are far from artificial intelligence.Academic environment is very important, of course, but the real understanding of machine tool is still not mature enough.
