ICARUS Consulting GmbH provides development, planning and simulation of manufacturing processes for the digital factory.
Founded in 1995, ICARUS Consulting GmbH was one of the first engineering consultants supporting the development, planning and simulation of manufacturing processes in Germany. The aim was to accompany customers through every stage of manufacturing planning via qualified consultancy and process management.
Additionally, ICARUS Consulting takes over all tasks regarding planning, design, 3D simulation, process optimization, as well as system and software development. The company’s more than two dozen specialists have gained extensive experience across various industries. Among its customers are car manufacturers and car manufacturer suppliers, aerospace businesses and engineering consultants, as well as rail and bus manufacturers.
Almost always, the tasks reflect global business challenges. “We are hired to achieve lower production costs, shorter project times or the trouble-free commissioning of new manufacturing plants,” says Volker Wildeboer, one of the two chief executive officers at ICARUS Consulting.
“Also, ergonomic workplaces, higher product quality, shorter lead times and higher output are in high demand.”
In fact, these are among the key factors that decide whether a company pushes global competition – or gets pushed by it.
As a progress trailblazer for its international customers, ICARUS Consulting relies on digital factory tools from the very beginning. Tecnomatix® solutions from Siemens Digital Industries Software are used to generate simulation models, set up production scenarios, design and optimize manufacturing lines, and program robots. Some 20 workplaces are equipped with the Tecnomatix solutions for plant design, robotics and automation planning. These comprehensive tools support answering particular customers’ questions with an accuracy of nearly 100 percent. On the other hand, already existing simulation models can regularly be used to optimize, modify or enhance manufacturing plants.
“Industrial processes are continually increasing in complexity,” notes Volker Wildeboer, chief executive officer at ICARUS Consulting. “Only by using simulation models are plant operators able to face this trend effectively. For this, the Tecnomatix solutions are the key to success.”
With expertise in manufacturing site automation and Tecnomatix solutions, ICARUS Consulting also supports the manufacture of wind power stations. In order to achieve the political goals regarding renewable energies just in the North Sea and Baltic Sea, more than 1,000 wind power stations shall be constructed every year during the next decades. These wind power stations have a hub height of over 100 meters and rotor blades up to 80 meters long.
The manufacturers of the gigantic stations must achieve higher quality and quantities in the production process to help secure a strong market position. Therefore, ICARUS Consulting creates simulation models of the production facilities for foundation, tower and rotor blades in an early stage using existing customer CAD models, library components and 2D plans. Boundary conditions like hall layouts are considered, as well as are customer specifications regarding cycle times and output. Different production scenarios provide information about the right utilization of manpower, machines, devices and robots.
Additionally, the scenarios support product variant testing and the selection of automation components. “With the simulation model, we ensure that the right devices are ordered on time, that the workplaces and buffers are arranged and that all means of transport are in place,” says Wildeboer. This prevents commissioning issues regarding the feasibility of individual operations or the availability of the entire installation. Also, existing manufacturing facilities are further optimized with the digital factory tools.
The rotor blades, being up to 80 meters long, are horizontally flanged to the future mounting point, in order to grind them and to apply gel coat and paint. In this process, the blades strongly deflect. This, as well as material characteristics, e.g., gel coat dries in a few seconds, complicate the programming of operating robots. Idle times during processing must not occur.
In the past, it often took months to optimally program the robots by using a teach pendant, also known as an online, manual-teach procedure. “With Tecnomatix, we develop the programs offline and go live in a few days,” says Wildeboer. “We are able to reduce production startup times significantly. Additionally, we improve the robot programs in a way that the quality of the rotor blade surface reaches its optimum.” This essentially determines the efficiency of the future wind power station – the higher the surface quality is, the less turbulence affects the blade run.
High quantities and short cycle times are typical reasons for performing a material flow simulation with Tecnomatix; however, for wind power stations, the enormous dimension is the deciding factor. “For a rotor blade of 70 meters in length, sufficient buffer space is rarely available,” says Michael Lüdemann, project director at Icarus Consulting. “When you are able to save a single component carrier, then the analysis costs are already amortized several times.”
Another field of application for material flow simulation is the elaborate logistics needed for constructing an offshore installation. The coordination of special transporters, which bring the huge parts from the manufacturer to the designated port, is very complex. Additionally, the right assembly order and the storage capacity of the port have to be considered to ensure quick and cost-efficient at-sea construction. “The costs for the special transporters alone justify the effort of an extensive optimization,” notes Lüdemann.
In the rail sector, robots for sandblasting wagons are programmed offline within two days. The onsite programming process used to cause an idle time of 14 days.
The automotive sector also has a strong need for material flow simulations. For example, in the case of just-in-time(JIT)/just-in-sequence (JIS) manufacturing, no two seats are alike due to customized variants. This creates a challenge in guaranteeing that the seats are always provided in the right sequence.
“Industrial processes are becoming increasingly Complex,“ notes Lüdemann. “Only by using simulation models are plant opera-tors able to face such trends effectively. Tecnomatix software offers the right solutions to address these demands.”
Wildeboer points out, “In this dynamic market environment, we were able to increase the throughput of two to three rotor blades per day by 200 to 300 percent. Of course, the corresponding automation and the in-advance validation within the digital factory were absolutely necessary.”
